Installation

Prepare your installation site by following the steps below: consult page “Rear panel” on page 10 for rear panel diagram indicating location of key connections.
1. For models delivered with a fuse attached to the AC cord, install the fuse before plugging the unit into mains power.
2. Ensure your electrical circuit has a good ground connection with all audio equipment connected to the same ground node to avoid noise or hum due to a ground loop.
3. Prepare all your devices (sources, projectors, amplifiers…) and keep them all powered down while interconnecting them to the ISP to avoid electrical discharges and damages, especially for HDMI interfaces.
4. Network should be running a DHCP server to enable the ISP to obtain an IP address.
Ventilation
The ISP is a cool-running line level component. It generates far less heat than amplifiers and many other components. It can be safely placed inside furniture or an equipment rack. However, it should not be tightly enclosed. Some airflow is desired. Fan need to be able to circulate air especially when the ISP is under heavy load. Keep at least 1″ space on sides and back panel.
Connecting to A/C Power
Plug the IEC-320 C14 end of the power cord into the ISP, then plug the other end into an approved and grounded A/C receptacle.
Connecting to Network
Using a CAT5e or better cable, connect the ISP to your local area network. See “Get Network Access” on page 11 to identify IP address.
Connect IR Interface (Optional)
Should you place the unit in a closed cabinet and still control it through IR, you can connect an IR receiver to the IR Input of the ISP (available from StormAudio on demand).

ISP Immersive Sound Processor

Connect Source Components
Legacy digital sources can be connected to the digital inputs 1-6. Stereo or surround analog sources can be connected to the Analog Inputs section. Analog input configuration is defined at “4. Main Audio In” on page 16. HDMI sources can be connected as well.
Connect to Display
Connect your displays using HDMI outputs. Note that outputs can be mirrored (same content) or independant (different content). For long distance we recommend usage of optical fiber and interface dongles. eARC audio return channel is only supported in HDMI OUT 1, while ARC is supported on both HDMI OUT 1 and 2 ports. HDMI Out 1 is linked to the Main audio path while HDMI Out 2 can be linked to an Audio Video Zone.
Note: when eARC/ARC is not used, it might be preferable to connect the screen to HDMI OUT 2 due to CEC commands on HDMI OUT 1 that some screen cannot override.
Connect Audio Outputs
If you choose to connect your outputs at this step, take note of which output number is routed to each channel so that you can map them appropriately in a later step. Otherwise, when you setup the theater using the web UI, the default outputs will be defined for you. At that point, you can connect your amplifiers based on the default output channel mapping. Using XLR cables, we recommend length <3m.
First Run
Upon first run, you must configure the ISP according to your specifications using the web based user interface. There is no on-screen display or provision to configure the unit using the front panel.
Power On
Turn the main switch on the rear panel to the ON position.
The front panel display will show the StormAudio logo for a few seconds, then will go blank as the ISP enters sleep mode. The power LED will show steady red.

Once in sleep mode, press the front panel POWER button. The ISP will begin the startup sequence. During the Initialization process (about 30s) the LED will blink green until the unit is ready with a steady green LED. Initialization process can be shorten at the cost of more standby power consumption. See “Settings” on page 36 to adjust this.

Get Network Access
1. When the Home display screen is shown, press the Home/Access button (rounded square) to access the Adjustment Menu.

Input Settings
The ISP permits the installer to create access to sources in a very intuitive way for the end user. The installer is advised to title inputs thoughtfully and without ambiguity. No longer must an end user remember which physical input is attached to a particular source component. Further, only inputs specifically configured as ACTIVE will be available from the remote control. Finally, multiple inputs can be created from a single source component for the purposes of loading separate settings. For example, you may have an input titled CD Music’ that accesses a BluRay player attached to HDMI 7 that by default downmixes everything to stereo and another input titledBlu-Ray Movie’ that accesses the same source component but upmixes all audio to Dolby Surround.
1. Active
Any input with a grayed Y is accessible from remote controls. To disable access to an input, click the Y and it will change to a N and gray out the entire row thereby disabling access to this input. You are advised to disable any input with no source component attached.
2. Input
This is the name of the input that will appear in remote control applications. By default, the name is the same as the default audio input. You may type up to 10 characters in this box and change the name to something more intuitive.

3. Video In
For any given input, you can map separate video and audio inputs except that when the audio input is an HDMI input, the video input must be the same HDMI input. “None” may also be chosen when no video is desired.
4. Main Audio In
For any given input, you can map separate video and audio inputs for the Main Theater audio path, except that when the audio input is an HDMI input, video must be the same HDMI input. Note that the analog input matrix may be selected as: 4x Stereo RCA, 3x Stereo RCA + 1x Stereo XLR (Elite and Evo models), 5.1 RCA + 1x Stereo RCA or as a 7.1 RCA input.
5. Zone2 Audio In
The ISP offers a dual source selection so that you can have one source playing in the Main Theater defined in point 4 above and another source playing in the other defined Audio Zones (see “Building a Theater – Defining Channels” on page 18 for the Theater and Audio Zones creation). The Zone2 Audio input path definition will vary depending on the Matrix mode defined in the “Settings” on page 36 (optional on Core). Make sure to first select the appropriate mode for your overall audio video system. When selected, adjust the “Zone2 in” path according to below recommendations.

ISP Immersive Sound Processor

· Mirror Mode: It is not possible to define the HDMI audio path as the Zone2 audio path. For device with HDMI connection, It is recommended to connect and define an Input with two physical connections to the ISP such as HDMI for Main Audio In and SPDIF/RCA for the Zone2 Audio In. Doing so, selecting this Input will take the correct physical connection automatically depending on the Theater or Zone playback. For other inputs (digital/analog), you can defined the same audio path, such as Stereo 1 for both the Main and Zone2 audio path.
· Zone2 AV Mode: In this mode, with HDMI sources, we recommend to define HDMI as the Zone2 audio in path. When selected as a Zone2 source, the player will automatically provide the needed 2ch version of the content played to the Zone2 path. Other sources can follow same rules as in Mirror Mode, so same input for both paths.
· Pass Through Mode: In this mode, it is still possible to define a Zone 2 audio in path for the HDMI sources to use them in the defined Audio Zones, in a similar way it is done in the Mirror Mode described above. In this case, audio extraction from the HDMI path won’t be possible, so not selectable as a Zone2 in audio path.
In any case, selecting a source will automatically take the correct physical connection depending on the Theater or Zone playback.
Note that ROON can only be selected as a source for the Main Theater. Zones can access ROON playback only when USE ZONE2 SOURCE is OFF in a given Audio Zone., thus getting the same content as the Main Theater.

6. Preferred Upmix
On a per input level, you may choose to engage a particular upmixer, or leave the option set to none. This setting overrides any preferred upmix defined as part of a preset. So, if a preset is to be used in conjunction with this input, and that preset includes specifying an upmix, leave this setting to None.
7. Trimmer
Each input may have the audio attenuated by a specific value in an effort to level match source components and yield an expected volume level in the room regardless of source selected. No gain can be applied, only attenuation. The range is -30dB to 0dB with 0.1dB step.

8. AV Delay
Each input may have a synchronization delay set between video and audio. This range is 0-100ms in 1ms increments.
9. Triggers
The ISP can trigger connected devices ON using the 4 DC trigger output jacks on the back when a specific input is selected. Most commonly, this is used to power on the source component connected to a specific input. To enable this feature, the desired trigger must be set to “Auto Switching: Enabled on Input” in the Settings menu. See “Triggers” on page 39. To engage a trigger based on input, click the light gray N. It will turn into a dark grayed Y when the trigger will be activated upon selection of that input.
Roon Ready
The ISP is a Roon Ready certified product and can therefore be part of a Roon streaming ecosystem. Only few steps are required, as described below.
1. Roon input definition
For the ISP to be visible in the Roon ecosystem it is first required to create an input that would select the Roon audio path. Following the steps 1 to 4 of “Input Settings” on page 16, create a new input and select “Roon Ready” as Main Audio input. It will then be available on all remotes and discoverable by the Roon core.
2. Roon core settings
In your Roon core, whether embedded in your favorite NAS or a Roon Nucleus product, access the Settings page and the Audio section.
17

In the Roon ready area, Enable the StormAudio ISP. Once enabled, you can customize it (name, audio settings), as shown below.
ISP Control via Roon app
Roon control, whether through the desktop or phone app, allows for multiple actions: ISP power up and down, automatic Roon input switch at playback launch and volume control, as shown below.

Building a Theater – Defining Channels
To assign analog outputs to particular channels, you must build a theater. A theater may occupy as few as 2 channels or as many as 16, 24 or 32 depending on the ISP model or optional module assembled. Any channels left over may be assigned to secondary multi-channel theaters, 2 channel A/V zones, audio only zones, mono zones or headphone zones. A physical output can only be assigned to one theater or zone per Layout.
1. Layouts
If it is planned to have different usage of a speaker in an installation, the Layout function should be used. It is possible to create up to 6 different Layouts, providing total flexibility in how speakers are used on each of them. A layout is a new set of speaker assignments, up to the limit of what is supported by the ISP (from 16 to 32ch per layout). By default, a Main layout is created that will allow you to define a first set of speakers assignments, whether Theater and/or Audio Zones.
Creating a new Layout resets the output mapping in this Layout. Thus, you may need to remap the outputs to ensure a speaker gets the appropriate signal defined in the Theater and/or Audio Zones.
Example of Layout usage:
· creation of subset of a Theater, for example, defining a 13.1.10 constellation in the Main Layout and define 7.1.4 in a different Layout using replicated speakers instead of discrete feeds
· multi-purpose room that can be used in “projection mode” in one direction and “TV mode” in another direction
In case Audio Zones are created in the Main Layout, it might be recommended to maintain them in all Layouts, so that when changing from Theater usage (by the change

ISP Immersive Sound Processor

of Layout), the Audio Zones keep working seamlessly.
This choice is made at the creation of a new Layout as shown below (“Keep Zones?”)
following selection of “+” in the Layout tab
area.
You can rename the Layout and then select create. This will open the new Layout to configure. Note that a Layout can be deleted, except the Main Layout that is the default one.
2. Delete Theater
By default, the ISP ships with a 2.1 channel theater configured. To build your own, delete this theater and create a new one. Select the Trashcan and validate the removal when prompted.
3. Create and Configure the Theater
Select + to create a new Theater. You will
reach the Speakers configurator where you will be able to define each layer of the speaker installation: base, height and top layers.
A. Choose using the left and right arrows which speaker combination you expect for the layer amongst predefined options

populated automatically depending on the channels decoding capability of the ISP version.
B. For each speaker, you can define whether it is a full bandwidth or an active multiway one, with up to 4 ways definable. At this stage, only the number of ways is requested: filters details will be defined in the specific “Multi-way Loudspeaker Setup” on page 23.
C. The Center channel can be turned to Phantom mode, the signal being played in Left and Right channels, removing the need to have a physical center channel in the installation.
D. Top channels can be defined as Dolby Atmos Enabled for the case up-firing speakers are used. In such case, select the base speaker location which can be either the “Front”, “Side” or “Back” speakers position, depending on the base layer definition. Keep «None» for normal downfiring in ceilings speakers.
E. For each speaker, you can define whether replication is required. Use this feature for multiple subwoofers or multiple rows of surround speakers declaration or any speaker you wish to replicate. In case there is no subwoofer in the system, please select “0” in the subwoofer field.
F. Press Next to reach the next layer and follow again steps A to E until all three layers are defined.

G. At the end, a summary of the Speakers Configuration is shown. A four digits description is given following this order:, “Base Layer . LFE . Height Layer . Top Layer”.
H. It is possible to get a 3D view of the Theater, toggling between 2D and 3D.
I. Save to exit and reach the Speakers edition page loaded with the default audio profile “New profile 1”.
Zones
Zones are mono or stereo, and with or without a link to video output or can be dedicated to headphone playback when used with an external headphone amplifier. Stereo Audio/ Video and Headphone Zones include provisions for adjusting lip sync. Audio only zones do not. Zones occupy unused channels and can play concurrently with a theater or without one. Note that system wide, you can select one input for the main theater (Main Source) and one Zone 2 input used by all the audio zones (Secondary source). You can choose the Zone to play either the Zone2 source or follow the Main Theater source. Zones have all the same features of a main theater except that channels are always “Large”, they cannot include subwoofer channels, and they are limited to mono or stereo. In order to control a zone, it must be included in the preset that is currently selected in the remote control. See “Presets” on page 35 for more details.
Profiles
For each Theater, Sub-Theater, and Zone, there is a default profile created. You can save multiple profiles for different listening preferences with specific speakers settings (such as different EQ profiles based on content type).
Profiles can be recalled as part of Presets (see “Presets” on page 35). A profile includes: Speaker definition (multi-way, levels, delays), bass management, manual EQ, and Dirac filter design if applied.

1. Rename
You can rename a profile using Latin-1 table characters. No special character allowed.
2. New
Click New to build a new fresh profile.
3. Duplicate
Build a variation of a saved profile. For instance, you cannot edit Dirac reference profiles directly although it can be useful to tune levels of replicated speakers. In such case, create a duplicate of the reference profile and edit it to adjust the needed parameters.
4. Save
After any changes to a profile are made or creation of a new one, you must SAVE your changes.

Individual Channel Adjustments
Once your theater is defined, each channel can be individually adjusted. Child theater can also be created, see “Child Theater / Sub Theater” on page 29.
1. Channel Status
Each channel is enabled by default. To disable a channel, click the ON button. It will turn to OFF and audio will no longer be routed to that channel. Note that audio will not be rerouted to other channels. Channel status is set per Theater / Zone and is not stored as part of a profile.
2. Channel Type
When equiped with a Digital Output module, each channel can be assigned to an Analog or Digital output.
3. Channel EQ
Each channel can have up to 20 filters cells configured selecting the wheel icon. Channel EQ can be bypassed by selecting ON/OFF. See “Channel EQ” on page 24 for detailed EQ options. EQ settings are stored as part of profiles.
4. Signal
Indicates which signal is routed to this output. Should you desire to remap signal routing, you can do so with Output Mapping. See “Output Mapping” on page 28 for details.
5. Channel Name
Name can be customized with up to 24 characters from Latin-1 table. No special character allowed.

6. Delay per Channel
Choose whether to measure channel delays in meters (default), feet, or milliseconds. Each channel should have distance/delay set between that loudspeaker and the reference seating position. You can define this in meters (default), feet, or ms depending on your setting in point 6 above.
7. Level
Set the level of each channel in between -100dB and +12dB in 0.1dB increments. Best practice is to set other channels to a negative figure relative to the loudest channel to avoid clipping when possible. Global gain makeup can be applied to the theater when the relative level of the theater is too low (usually a result of a high degree of correction due to Dirac Live’s mixed phase filters). Use global gain makeup judiciously to avoid clipping.
8. Limiter
To prevent distortion due to loudspeaker overdriving or amplifier clipping, you may wish to engage a limiter on a channel. When enabled, a compressor will attenuate audio above the threshold set by the Limiter Value for that channel back down to that value. For instance, if the limiter is enabled and set to -3dBfs, any audio that exceeds -3dBfs will be reproduced at -3dBfs. By their nature, limiters are not ideal acoustic solutions, but this feature can prevent subjectively worse sounding distortion, or in extreme cases, damage to loudspeakers or amplifiers. If you find that you are aggressively using the limiter function, you are encouraged to upgrade loudspeakers and/or amplification.

21

9. Tilt EQ
For speakers behind a motorized screen for example, you might need to change their “audio brightness” depending on the screen position up or down. TiltEQ allows the sound to be darker or brighter.
10. Polarity
Check the box for any channel in which you wish to invert signal polarity.
Test Tone Generator
The ISP includes a highly configurable test tone generator which can be used to help manually calibrate channels.
11. Volume Reference
It is good practice when calibrating systems to always work at a reference level such as 85dB C-weighted. Before activating the noise generator, make sure the master volume is at a low level. Set and recall a reference master volume value. Click SET once you have dialed the value you’d like to store. Click RECALL to quickly return to that value.
12. Generator
Click this button to turn on the tone generator. It will automatically start with Group 1 with green highlight on the active channels.
13. Setup
Unlike traditional generators, the ISP plays tones per channel group. Click Setup to define the groups and the channels they contain. For example, if you have 2-way active loudspeakers, you may wish to group the high frequency and low frequency component of each into one group.

14. Noise Selection
Choose the type of noise or tone created by the generator.
· Sine: Generates a sine wave at the frequency specified.
· Pink Noise: Generates full bandwidth pink noise.
· Pink Noise 400Hz-4kHz: Generates pink noise band limited to one decade. This is particularly useful when setting relative levels between channels with dramatically different useful bandwidths. Remember SPL meters measure not only sound pressure but also bandwidth.
· External: it is possible to use an external noise generator connected to one of the ISP input (except XLR input). This is usually required when using an external tool providing its own stimuli (Room EQ Wizard is one of them, see “1. REW import” on page 25).
15. Gain
The gain figure can be set so that the noise generator operates at a level at or below that of a normal source playing at 0dBFS. Default is 0.1 (-20dBFS).
16. Group -/+
When the noise generator is active, use this function to play the noise through different groups defined in “13. Setup”.
17. RTA
When a USB microphone (such as the optional Microphone Mini Kit) is connected to the ISP, you can use the Real Time Analyzer together with the Noise Generator to visualize the response of loudspeaker groups in the room. Note that the built in RTA is not accurate enough to use for calibration, but is useful for getting a good idea of the approximate response of the system. Maximum level of the capture can be set by adjusting Mic Ref Level. Graph vertical scale can be changed from Logarithmic (default) to Linear.

18. DIRAC
See “Dirac Live®” on page 30 for use of Dirac Live® Calibration Tool.

Multi-way Loudspeaker Setup
During the initial Theater Definition setup, you have the option of defining any speaker as multi-way. Doing so will assign 2 to 4 output channels to each speaker instead of 1. In this configuration, more than 1 amplifier channel will be used per loudspeaker, and the ISP will perform the crossover function for each loudspeaker.
All settings detailed in section “Individual Channel Adjustments” on page 21 also apply and will not be covered again here. This section only describes the differences notable for multiway loudspeaker configuration.
1. Channel Name
By default, the channel names are named by the signal they receive. For clarity, you may wish to rename these according to the signal they reproduce e.g. Left Front High, Left Front Mid, Left Front Low. Use Latin-1 character table with no special character.
2. Signal
Note that in this example (Left Front is a 2-way active loudspeaker), Each of the first 2 channels receives the same Left Front signal.
3. Multi-way Management
Use this section to filter the signal for each section.
· Section: Choose whether each channel reproduces Full Range, Low Pass Filtered, Middle (band pass), or High Pass Filtered audio. Two-way speakers will not have Middle option.
· Crossover Frequency: When the section is chosen as anything other than Full Range, set the crossover frequency for the Low and High Pass filters for each section.

6
5
· Slope: For each filter, select a slope. Options are Butterworth (12dB / oct, 24dB / oct, 36dB / oct and 48dB / oct), Linkwitz Riley (6dB / oct, 12dB / oct, 18dB / oct, 24dB / oct, 36dB / oct and 48dB / oct) and Bessel (12dB / oct, 24dB / oct, 36dB / oct and 48dB / oct).
4. Channel EQ
For each channel, you can adjust EQ by selecting the Wheel. EQ can be bypassed to compare with and without equalization selecting On or Off.
5. Delay
Set the delay of each section. For active multi-way loudspeakers, it may be helpful to do this in milliseconds and measure timeof-arrival differences at the crossover point when using LR or BT6 filters to time align each section of a multi-way loudspeaker.
6. Level
Active multi-way loudspeakers almost certainly have different sensitivities per module. Set the relative level of each here. When possible, use 0 as the maximum figure and attenuate other channels to match the loudest channel. You can also set global makeup gain for the entire theater as described in “7. Level” on page 21.
Note that after making any changes, you must press the SAVE button near the top right of the screen or you will loose your changes.

Channel EQ
Each channel can have up to 20 filters cells for equalization, including additional crossover capabilities.
1. EQ Export
The complete EQ settings can be exported into a file with .txt extension that can be reloaded in any ISP using the REW import function (see “1. REW import” on page 25).
2. EQ Bypass
When developing a custom set of EQ per channel, it is sometimes helpful to bypass the entire group of EQ to check your progress against the starting point.
3. Graphical UI
The EQs defined are visualised in a graphical window. Individual and combined EQ curves are shown, providing an instant understanding of EQ impact on the correction curve.
4. Create EQ
To design EQ curves for any channel, you need to add EQ definition line using the Create EQ button.
5. Filter Shape
Each filter must begin with a variation of one of 5 types.
· Low Pass: Continuously declining output above a cutoff frequency at a defined rate.
· High Pass: Continuously declining output below a cutoff frequency at a defined rate.

· Bell: Band pass or cut filter with a defined center frequency, boost or cut amount, and Q.
· Low Shelf: Boost or cut frequencies below a cutoff frequency by a fixed amount and adjust the Q.
· High Shelf: Boost or cut frequencies above a cutoff frequency by a fixed amount and adjust the Q.
For LPF and HPF choose a type and slope amongst Butterworth (12dB / oct, 24dB / oct, 36dB / oct and 48dB / oct), Linkwitz Riley (6dB / oct, 12dB / oct, 18dB / oct, 24dB / oct, 36dB / oct and 48dB / oct) and Bessel (12dB / oct, 24dB / oct, 36dB / oct and 48dB / oct).
Delete
Unused EQ line can be removed using the Bin button.
6. Status
In the course of designing your filter, you may wish to measure or listen to progress compared to the absence of that filter. Click Active “No” to temporarily omit that filter from the aggregate curve. Click “Yes” to activate it back. You can also decide here whether it is shown in the visualization curve by checking the Graph item.
7. Quality Factor / Bandwidth
Bell and Shelf filters require that you specify a Q (from 0.05 to 32). High Q affects a narrow bandwidth, and low Q affects a wide bandwidth. You can enter this number directly in the text box or increment/decrement by the amount chosen in the header row

ISP Immersive Sound Processor

using the +/- buttons to the right. Or, click a fractional or multiple octave button to automatically calculate Q.
8. Gain
Bell and shelving filters require that you set the amount of boost or cut. You can enter this number directly in the text box or increment/ decrement by the amount chosen in the header row using the +/- buttons to the right.
9. Frequency
Each filter requires that a center or cutoff frequency be specified. You can enter this number directly in the text box or increment/ decrement by the amount chosen in the header row using the +/- buttons to the right.
10. Save
Make sure you SAVE the EQ settings before changing from channel or leaving the page.
11. Channel Select
Select the desired channel to equalize here.
12. Copy to Channel
You may wish to duplicate your filter set to another channel without manually rebuilding it for each identical channel. Select one or more channel(s) to copy the current filters to and click COPY.
Note that after making any changes, you must press the SAVE button near the top right of the screen or you will loose your changes.

Room EQ Wizard integration
1 1. REW import
The ISP offers the possibility to use external Room Correction tool such as the Room EQ Wizard (REW). REW offers very advanced measurements and filtering capabilities where you can define equalization and measure the effect in both time and frequency domain. This gives a total flexibility for ISP users to go from a fully automated approach with Dirac Live to a fully manual approach that REW offers.
To allow for importing filters defined in the REW tool, you must make sure that you first set the REW tool for StormAudio ISP compatibility and select “Export filter settings as Texts” in the tool.
Once done, you can then do your EQ for each channel and export the equalization as a “*.txt” file.
In the ISP, select “REW Import” and load the file corresponding to the selected channel. You will prompted for choosing between adding to or replacing existing EQs. Once selected, the EQ page will then be loaded with the REW defined filters.
Note that you can define up to 12x Parametric EQ and 2x High Pass or Low Pass filters (up to 48dB slope) in the REW tool with the StormAudio compatibility mode.

Bass Management
Bass Management is one of the most important and critical part to adjust in the ISP in order to achieve the best bass response of your system depending on the speakers and subwoofers used but also on their integration in the room.
There are various use cases and this will mainly depend on whether you want to manage this manually, with more or less subtleness in what can be adjusted (Standard or Expert mode) or you go fully automated using the options Dirac Live Room Correction offer between Bass Control and Active Room Treatment. Bass Control will adjust your multiple subwoofers and speakers automatically but will not allow wide bandwidth speakers to reproduce the Bass. Active Room Treatment will consider all capable speakers to reproduce the Bass and provide a well controlled bass reproduction in any room.
1. Modes
The ISP offers three different modes:
· Standard: This mode is the basic mode, usually suitable for most of the use cases where the low frequencies are reproduced by subwoofers and with the need of a single crossover adjustment between each speaker and the subwoofers.
· Expert: This mode allows for more advanced adjustments such as the definition of Bass Zones that can be flexibly routed to any Bass reproducer in the system, independant crossover adjustment between subwoofer and speakers or when speakers have to be used as Bass reproducer.
26

While it can help achieve greater subwoofer integration and low frequencies reproduction, it should only be used by calibrators with sufficient skill otherwise comparably poor results may be inevitable.
· Dirac: The Dirac mode is only accessible when applying the Dirac Live Room Correction process and selecting between Dirac Live®, Bass Control or Active Room Treatment modes. In this Dirac mode, the Bass Management or bass routing will be set in the Dirac tool with no possibility to override them in the ISP UI (all adjustments will be grayed out). See “Dirac Live®” on page 30.
2. Size/filter
When in Standard or Expert modes, the system offers the possibility to define how the bass are exctracted from the speakers and redirected to the bass reproducers, whether they are subwoofers or speakers.
· Small: When a channel is set to Small, bass in this channel is redirected to the Bass reproducers. The channel is high pass filtered according to the HPF frequency and slope. Low frequencies are routed to the bass SUB channel according to LPF frequency and slope. Individual HPF and LPF definitions are only available in Expert mode. Small speakers cannot have SUB bass channel or LFE bass mixed in.
· Large: Channel is not band limited. When a channel is set to Large, no bass is redirected from this channel to the bass SUB channel. Use this setting when the loudspeaker has sufficient bandwidth and output capability to reproduce low frequencies. Channel can have SUB bass channel and/or LFE bass mixed in.

ISP Immersive Sound Processor

· Large and Sub: Channel is not band limited, but a copy of the bass for this channel is routed to the bass SUB channel as well. Set the frequency below which bass should be sent to the bass SUB channel and the slope at which the crossover occurs.
· Large with Sub: This special case is only available in the Expert mode. It enables you to effectively split a full range loudspeaker into a “small speaker” plus a “subwoofer”. The HPF frequency and slope define the characteristic of the “small speaker” portion. LPF frequency and slope define the virtual “subwoofer” characteristic. Both are mixed before being routed to the speaker, thus making it a Large one from an acoustical stand point.
Subwoofer channels have specific settings. By definition, subwoofers have limited bandwidth and some are more limited than others.
· Low Pass LFE: When this is set to ON, the subwoofer channel has a low pass filter applied according to that channel’s Frequency and Slope. This is designed to limit the channel’s ability to reproduce the upper portion of the bass spectrum. This is usually done to prevent the subwoofer from contributing midrange distortion.
· Subsonic SUB: When this is set to ON, a high pass filter is applied to the channel which restricts the subwoofer’s ability to reproduce very deep bass according to the frequency and slope defined for that channel. Many subwoofers, especially smaller models do not have the amplifier power or driver displacement required to accurately reproduce very deep bass. By actively filtering very deep bass away from the subwoofer, it is better able to reproduce bass within it’s useful bandwidth.
3. Frequency
When the channel is set to Small, Large and Sub or Large with Sub, the crossover Frequency defines the point below which bass in this channel is routed to the bass SUB channel in standard mode. In Expert mode HPF to the speaker and LPF to the bass SUB channel can be adjusted individually. Note that the frequency is the -3dB point along the slope defined in the next column and is not an absolute cutoff point.
4. Slope
The rate at which bass is `crossed over’ into the subwoofer when the channel is set to Small or Large and Sub. Linkwitz-Riley, Bessel and Butterworth type filters are available

with 12dB to 48dB / octave slope (8th order).
5. With LFE
When a channel is set to Large, Large and Sub or Large with Sub, this channel can optionally reproduce LFE bass which would normally be the sole responsibility of the subwoofer channels. When set to None, no LFE will be mixed into this channel. When set to a figure between 0dB and -20dB, LFE bass attenuated by that figure will be mixed into this channel. This feature is useful when the main channels have sufficient bandwidth AND dynamic range to support the subwoofers in creating an appropriate amount of bass sound pressure in the room.
6. Bass Routing
In Expert mode, it is possible to define multiple bass SUB channels, Bass Zones, made of the bass redirection of chosen speakers.
Selecting Bass Zone Setup will give access to a definition popup. Up to 6 Bass Zones can be defined. There is always one by default receiving all the redirected bass. More can be activated by toggling the button to Y. Then adjust the redirection level expected for a certain channel in the desired Bass Zone. Once fully defined, you can SAVE to exit the popup.
7. SUB Routing
For each Bass reproducer (Large, Large and Sub and Large with Sub channels), you can define which Bass Zone it should reproduce. When set to None, no Bass Zone will be
27

mixed into this channel. When a Bass Zone is set, define the mixing level to apply between 0dB and -20dB. This level should be adjusted considering the overall acoustical response of the system.
This feature is useful in multiple use cases:
· When the room is big enough, it is a common practice to have one or two subwoofers below the screen reproducing the LCR redirected bass and the LFE channel, one or more subwoofers in each side of the room reproducing their respective side speakers bass and finally one or more subwoofers in the back of the room handling the surround rear speakers low frequencies. You can even add one or two subwoofers for the Ceiling speakers bass reproduction.
· When speakers are capable enough in the low frequency to reproduce the bass of the system, you can emulate the same system response as with a speaker and subwoofer combination, by carefully creating the Bass Zones and routing them to the appropriate speakers.
The Expert Bass management is a highly flexible tool that can bring ultimate bass performance. Nevertheless, one must keep in mind that such approach require to monitor the adjustments by careful measurements to ensure the right balance of bass reproduction is achieved. Also, using speakers as bass reproducer require heavy power handling capability to allow for reasonable acoustical pressure in the room in the low frequency region without reaching their limit.
8. Subsonic filter
In Exper mode, there is the possibility to adjust a Subsonic filter for each Bass reproducer, whether being a speaker or a subwoofer channel. Change the setting from None to any desired slope (from 12 to 48 dB) and adjust the crossover frequency.
9. Bass delay
Each Bass Zone and LFE reproduced channel has an individual delay adjustment, useful to carefully align the phase response of the system
Note that after making any changes, you must press the SAVE button near the top right of the screen or you will loose your changes.

Output Mapping
Should you wish to map a physical analog output channel to a loudspeaker other than the default assignment, you may do so from the Main Speakers page. Each Layout has its own Output Mapping. It is therefore possible to define different usage of a given connected speaker. Click Output Mapping.
Using the New Output column on the right of the pop-up menu, select a new output channel assignment. If you choose a currently occupied new output channel, that channel will be automatically reassigned (swapped). Save to exit and go back to Main Speakers summary page.

Child Theater / Sub Theater
You may optionally create alternate speaker definitions in your theater with some restrictions. For example, if you wish to have music playing before the movie plays before everyone is seated and quiet, you might only want that music playing from the overhead speakers so as not to interfere with conversation. In this case, you can define a child theater so that stereo left/right audio is played only through the top speakers (as in the example illustrated above).
Child theaters behave just like zones or main theaters in that they can be selected as outputs, programmed into presets and can have multiple profiles, including with specific Dirac filters.
Note that although multiple Child theaters can be designed per main theater, signal assignment is common to all.
1. Create Child
From the Main Speakers page, Edit your theater. Click Create Child. A window will appear with a list of loudspeaker names and their channel ID.
2. Zone Signal
For each loudspeaker, select the signal to be played. You may choose between Stereo Left, Stereo Right, Mono, or None. Subwoofer channels can play Subwoofer signal or None.

3. Keep Dirac Profile
If you have created a Dirac profile for the parent theater, you have the option to retain that calibration for the child theater. Note that it might be recommended to run a new Dirac calibration in case the listening area of the Child Theater is different from the Theater mode. To do so, follow the same process as defined in the next page.
4. Save/Close
Save when done, or Close to cancel.
5. Bass Management / Delay Level Phase
Child theaters have comparably limited options compared to full theaters. If a child theater includes a subwoofer channel, the full range channels are forced to small. In this case, you can adjust the crossover frequency, slope and subwoofer subsonic filter. If no subwoofer channel is enabled for the child theater, the main channels are forced to large. No Expert Bass Management is available for Child Theaters.

Dirac Live®
Dirac Live is a highly advanced calibration tool which uses sophisticated mixed-phase filters to compensate for loudspeaker and room deficiencies in order to provide optimal acoustic performance of your theater.
The Dirac Live® tool (3.x and onward) is free of charge and available on Dirac Website after registering (https://live.dirac.com/register/) and the calibration kit is usually purchased by the installer through their dealer. Stormaudio ISP comes by default with the activation of both Bass Control and Active Room Treatment add on modules which add to the standard Dirac Live room correction suite the ability to also include the bass management with any number of subwoofers and speakers used in the installation. This is enabled automatically in the tool once the ISP connection is confirmed.
All Theaters, zones, and child theaters can be calibrated with Dirac Live.® Presuming you have a calibration kit, prepare your ISP for calibration by following the steps below. Warning: do not use the remote controls to adjust volume during the process.
1. Define Speakers
For each theater or zone you will calibrate using Dirac Live® (except Headphones and Downmix), ensure that you have correctly defined each speaker’s Size/Filter, multi-way parameters or manual equalization (refer to “Channel EQ” on page 24).
In case you decide to calibrate the subwoofers manually, you also have to define the Bass Management parameters such as Frequency and Slope (see “Individual Channel Adjustments” on page 21) as this won’t be possible to do so after the Dirac calibration process unless you duplicate the Profile.
In case you want to use the Bass Control or the Active Room Treatment (ART) module of the Dirac Live tool that will be described in the next pages, you can skip the bass management adjustments and move to the next step. We recommend to use ART.

2. Download and install Dirac Live® 3.6.x Calibration Tool Software
You can download a Mac or PC version of the software at https://www.dirac.com/live/ downloads/ or on the StormAudio Client Portal (www.stormaudio.com). Depending on your ISP model acquisition date, the ART licence shall be bought from Dirac.
Install the software on the laptop you will use to calibrate the ISP. Use the Dirac account credentials to log in the tool.
3. Prepare Calibration Hardware
StormAudio recommends using the UMIK1 USB microphone that is part of the Microphone Mini Kit available in StormAudio’s catalog, other hardware may be compatible with the Dirac Live® Calibration Tool. This guide will only cover UMIK-1 use case.
Connect the UMIK-1 to your laptop. Note the serial number on the microphone and navigate to https://www.minidsp.com/ products/acoustic-measurement/umik-1. Enter the serial number to obtain your unique calibration files.
4. Choose Theater or Zone to Calibrate
On the Main Speakers page, EDIT the theater or zone you wish to calibrate.
5. Select Base Profile
Select the profile which will serve as the basis for your Dirac Live® calibration from the dropdown menu.
6. Setup Dirac Groups
Group separate elements of a single active loudspeaker together e.g. Low, Mid, and High components should be in a single Speaker group with the same index.
Depending on your bass management preference between fully automated through Dirac or manually adjusted with your own tool, the declaration of the subwoofers will be different. For manual bass management It

ISP Immersive Sound Processor

is recommended that if your theater includes multiple subwoofers, you manually correct levels, EQ, and delay for each and then group all of them together for the purposes of Dirac Live calibration. For Active Room Treatment or Bass Control, keep them separated. Click the SETUP button (A) beside the Dirac button.

· Dirac Live: This mode provides the regular Dirac Live® design with per speaker target curve and standard Dirac Live® filters calculation (so called Dirac Live® Room Correction)
· Bass Management: This mode provides regular bass management filters with standard Dirac Live® filters design and calculation including each sub-woofer gain being scaled by 1/(numbers of sub woofers) to match the target curve.
· Bass Control: Selecting this mode, the filter design will harmonise the sub- woofers and non-subwoofers speakers in the lower frequencies using tailor made phase filters, delay and gains.
· ART: Selecting ART will enable the Active Room Treatment proposing to use all speakers and subwoofers to actively compensate for room issues under 150 Hz.
In the next parts, we will focus on the Active Room Treatment mode. With ART, we’ll introduce the notion of Main and Support

speakers. Any speaker can be a support of another Main speaker. For detailed explanation on ART, please consult website and tutorial videos to get more insights.
14. Support speakers definition
For each Speaker group, you can define which group will support it in the (A) area.
· By default the selected group will have its speakers supporting each other. This can be disabled by clicking on the Support range of the group.
· Other groups can be added by clicking on the (A) area below the Main group. A default estimated support frequency range will be proposed, limited to 50 Hz for the Speakers and 20 Hz for the subwoofer. Adjust this range (B) according to the Speakers and Subwoofer specifications sheet for the low frequency, to avoid overload at unsupported low frequencies. For the Main speakers, the low frequency of the range defines the bass management crossover for this group. You can also adjust the max support frequency (max is 150 Hz).
· Subwoofers will usually offer the widest Support frequency range. Depending on the Sub location and type, it might be preferred to limit their high frequency cut so to not be able to hear and locate them. ART acts down to 20 Hz. It is possible to extend the Speaker/Subwoofer response to the infra bass by clicking the (C) box and adjust range to 20 Hz. System will go down to 10 Hz.
· Selecting a Group activates filters, as many as dots shown in (D) with a max possible number that will depend upon the unit and the speaker configuration defined. With this limit, not all Groups can be Support. Some arbitration might be required.

15. Target Curve
In Dirac Live® ART, just as in other Dirac Live® modes, the color and balance of the sound is set through a target curve. In ART mode the target curve is set per Speaker group considering the input signal:
· You can adjust the correction window by moving the curtain (E) for the high frequencies. Low frequencies are defined by the overall extension that all Support groups can offer (20 Hz here).
· The input target curve shows the coloration for the complex summation of the Main speaker high-range above 150 Hz and a mix of the Main speaker (in its working range), the subwoofers and all Support speakers within their capability range below 150 Hz.
· The target curve defaults to a flat correction that can be adjusted. Changing (F), it will be possible to either use the auto-target feature with the (G) adjustments for low and high frequencies or by defining adjustable points. You can add points by right-clicking on the target curve and select “Add control point to”. You can also download StormAudio proposed target curves in our Download Center.
· Dragging the curve upward above the 0dB level on the Y-axis boost the affected frequencies. Correspondingly, dragging the curve downward under the 0dB level attenuates them.
It is possible to save or load target curve through the menu (H). Good target curve design is beyond the scope of this document, but there are some key points to remember.
· Do not attempt to boost bass of a loudspeaker
33

below its low frequency limit as this will only lead to high distortion and likely damage · High quality speakers usually benefit from limiting the correction window to low frequencies. · Ideal curves usually have a slightly downward slope. A loudspeaker may have a flat amplitude response on axis, but will rarely be flat off axis.
There are different possible viewing options available (I). Save the Target Curve through the Menu (H) for use in another channel or for other future use. Repeat for all speakers groups and then press Calculate (J) so the ART filters got calculated.
Note that calculation can take up to 15mn.
16. Corrected response
After the ART filters calculation is done, select the “Corrected” check-box in the plot options (A) to show the resulting input magnitude response for the selected channel. The corrected curve should conform to the target curve, as illustrated below.

B
If satisfied by the result, press “Process to filter export” (B).
17. Export Filters to ISP
In this last step, filters created in previous steps are exported to the ISP and combined into the new profile selected “5. Select Base Profile” on page 30.

Select the “empty” slot 1 (A), give a name and a description to your new Dirac profile (B). Save your project for future use (C) before selecting Export filter (D) and return to the ISP Web UI.
18. Return to ISP web UI
A popup has been updated to confirm that you wish to combine the Dirac Live

corrections with the base profile. The Name and Description Target curve can be changed using Latin-1 table characters. We also recommend to select the correct listening area that you used to make the Dirac Live® measurements (A). Click save (B) to continue. For corrections made to a zone, options are not available. Simply click save.
Note that each time you go through the Dirac Live® process, the former filter design gets replaced. Each time the calibration is run, a new profile is created with the new Dirac Live correction.
19. Return to Speakers Page
Now that you are back at the page where individual speakers can be edited, you will notice the new Dirac reference profile you named in the previous step is selected. New columns created indicate the calculated Dirac Delay and Dirac Level. No changes can be made to this reference profile. Should you wish to make changes, duplicate the profile, make desired changes to the duplicate, save changes to the profile and the theater. See “Profiles” on page 20.

Presets
Presets provide the installer with a way to group specific settings together into a scene which can be easily recalled by the end user from a remote control interface. By using presets, the installer can make use of the ISP – a highly complex and capable theater controller – extremely simple and enjoyable to operate.
Each preset includes the following settings:
1. Active
When Y, the preset shows up in the list of selectable presets on the remote control. When N, the preset information is retained, but not available to select from the remote control.
2. Preset Name
Title the preset according to the usage case. For instance, if the entire family gathers together to watch movies, Movie Night. Max of 12 characters from Latin-1 table, no special character allowed.
3. Theater
The preset must include which theater to play. The list includes Theaters, Child Theaters, and SphereAudio. It does not include zones.
4. Profile
Each theater can have multiple profiles to choose from. Select the profile which will be loaded by default when the preset is chosen.
5. Dirac Room / Dirac Curve
If the theater is calibrated with Dirac Live®, the listening area and curve description you entered in “18. Return to ISP web UI” on page 34 will be indicated.

6. Audio Zone
You may choose to route audio to 0 or more zones as well. When zones are checked, they are accessible and controllable from the remote control when this preset is selected.
7. Triggers
When triggers are set to “Auto Switching: On Preset” as described in “Triggers” on page 39, they can be assigned to presets here.
8. Upmix
Though the upmixing behavior is accessible from the remote control at all times, you may set the default upmix for the preset here.
9. Low Latency
In some use cases, it might be required that the audio latency gets reduced to its minimum, such as for Karaoke or live music sessions. In such case, it is possible to select the Low Latency mode that will help reduce the latency to below 15ms. Downside to this reduced latency is the deactivation of part of the post processing such as Dirac filtering. If the Theater was calibrated using Dirac, it might therefore be recommended to at least create a new blank audio profile and adjust the bass management and potentially some manual PEQs to meet expected sonical performance and create the related Preset.
Note: only RCA analog inputs or HDMI (forced to LPCM digital via EDID) can be used in the Low Latency mode. Selecting a source with Coaxial/Optical audio input will disable the Low Latency mode as we cannot know whether it is LPCM or RAW stream. Also, no decoding nor upmixing is possible.
10. Delete / Create
Delete any unused presets by clicking Delete in the correct row. Create a new preset by clicking Create.
35

Settings
The ISP includes a variety of system wise settings that are set in this menu that govern behavior of the unit. Ensure these are set as required for easy operation of the ISP and any attached devices. These are only accessible to those with Installer level access or Expert User if assigned by the Installer.
HDMI
There are two HDMI Output ports in any ISP.
· HDMI Out 1 port is linked to the Main Theater audio path
· HDMI Out 2 port can follow HDMI Out 1 content, be linked to an Audio Video Zone defined in the ISP or used to provide an unprocessed HDMI source to a TV or processor.
Below adjustments are available to adjust these two ports to match your audio video system requirements.
Output 1:
· ARC Mode: it is possible to get the audio from a TV connected to HDMI Out 1 through the HDMI cable. Select which mode you want to allow your TV set to provide through the link between ARC alone (Audio Return Channel) or ARC/eARC (enhance ARC). eARC allows for HiBitRate audio transmission, carrying Dolby Atmos and DTS:X stream.

· On Screen Display (OSD): it is possible to enable the On Screen Display function of the ISP to show status information in the screens with two positions to fit the best way 16:9 or 21:9 screens ratio.
· HDMI output audio: it is possible to provide the two channels downmixed version of the Main Theater audio stream to the screen(s) connected to the ISP output(s).
Output 2 – Matrix mode:

· Mirror Mode: In this mode, the two HDMI outputs will provide the same video content coming from the Main theater source selection.
· Zone2 AV Mode: In this mode, the HDMI Out 2 can be linked to an Audio Video Zone that would have been defined as described in section “Zones” on page 20. The video content played on HDMI Out 2 would depend on the Zone2 source selected and the “Use Zone2 source” mode chosen in the Remote Controls.
· Pass Through Mode: In this mode, the HDMI Out 2 will have its own independant source selection amongst defined HDMI sources. When selected, the HDMI source is directly routed to the HDMI OUT 2 unprocessed, allowing for decoding and processing to be made either on the connected TV or processor.
Output 2 – Other settings:

· ·
· ·
CEC:

Zone selection: When in Zone2 AV Mode, you need to define which Audio Video Zone is linked to HDMI Out 2 port so audio and video path are matching.
ARC Mode: it is possible to get the audio from a TV connected to HDMI Out 2 through the HDMI cable. Select ARC if you wish to allow for a corresponding source definition as described in “Input Settings” on page 16.
On Screen Display (OSD): as for HDMI Out 1, select the desired OSD mode on HDMI Out 2.
HDMI output audio: as for HDMI Out 1, select whether you desire the Zone2 audio to be fed to the HDMI Out 2 port. Note that it is not possible when in Pass Through Mode.

· It is possible to enable the CEC function. CEC offers a wide range of features. The ISP supports One Touch Play and System Audio Control features, in addition to the ARC related CEC commands always enabled.

IR Function Assignment & Commands
Expand Inputs and/or Presets to assign up to 6 inputs and 5 presets to discrete buttons on an IR remote control. Note that many “universal” remotes also have the ability to cycle through all available inputs or presets so even if you have more than 6 or 5 respectively setup, they can still be accessed via IR.

The ISP offers a front panel remote sensor. In case of a rack mount usage, it is also possible to use the back panel IR jack 3.5mm input to connect to remote IR sensor. It is also possible to daisy chain the input to the output jack to connect a IR blaster.
For direct device interface, please verify carefully the pin-out of the jack receiver/transmitter below.

The ISP IR code table has been added to Harmony Logitech database. It is therefore possible to create Activities involving the ISP as the audio reproduction device. Check for StormAudio and ISP Elite, brand and device names respectively in the MyHarmony app. See MyHarmony website for more information.

Do not connect directly to the Harmony Hub using a jack to jack cable as this can harm the ISP IR internal circuitry, use only IR receiver/ transmitter.

When using IR to control the ISP, we recommend activating the “Fast boot mode” defined in previous page to ensure there is no loss of IR commands while the ISP powers up, especially when using Logitech Harmony and the IR sequences it may generate.

Input/Output Setup
With the Optional 16ch AES/EBU Digital Input and Digital 32ch I/O AoIP modules installed (Elite and Evo models), multiple parameters need to be set, as shown below.

Parameters

· AES In processed: Defines whether the upmixing capability is enabled (<8ch input) or bypassed, so Processed/Upmixed with your Preferred Upmix or only post-processed up to 32ch respectively. In case of Processed enabled, the channel mapping is fixed: L, R, C, LFE, Ls, Rs, Lb, Rb. In case of bypass mode, see “16/32 channel digital input mapping” section below. Note that Lb/Rb are equivalent to Lrs/Rrs of DCI specifications.
· AES67 Frequency: With the Digital AoIP module, it is necessary to indicate what the network Sampling Rate is to allow for a stream to be defined. Choose between 48 kHz or 96 kHz.
· AES67 Module hostname: This is the name given to the module at the factory. It is adjustable in the AoIP module specific WebUI. Consult our Knowledge Base and the dedicated AoIP module documentation for more information.
· AES67 Module IP address: The AoIP module comes by default in DHCP. When connected to the network, you’ll find here the IP address that was automactically assigned, necessary for you to identify the module and define streams. Note that clicking on the IP address will open the AoIP module WebUI in another browser tab.
· 16/32 channel digital input mapping: The channel mapping between the audio server and the ISP defined theater might not match. Selecting EDIT will provide access to a mapping matrix allowing you to remap the signals accordingly.
· Download input mapping: you can download the input mapping as a spreadsheet.
38

· Downmix zone: define whether the dedicated downmix outputs feed an audio only zone or an audio video zone. When A/V, lipsync adjustment is available in that zone’s remote control functions, and that zone’s general delay can be set using the setting below in this page.
· Audio Control Range MAX: Set the maximum allowable level. +6dB (default), +3dB, 0dB.
· Volume Dim Level: To quickly attenuate the Master volume (but not mute it), a user can click Volume Dim. Set the level of attenuation here. Default is -20dB
· Default Volume Level: To ensure the ISP always starts up with a known Master volume level, it is possible to define a default volume level to which the unit should refer to at power up. You must select “On” to enable this feature. When “Off”, the volume will be loaded with the Last volume level. Note that the Default level is common to all Theaters and Zones defined in the system.
· IMAX Bass Management priority: The “IMAX
default” mode follows the IMAX® Cinema
recommendations with a Bass Management adjusted with a fixed 70 Hz crossover to any speakers, with no bass redirection to the subwoofers that will only reproduce the LFE signal. This mode is therefore only recommended if your system can accept such adjustments. If Dirac Live with Bass Control was used to calibrate the room, the Bass Control portion will be disabled and only the speakers filtering will remain in use. If the Bass Management was manually configured either in Standard or Expert mode, it will be
overriden by these settings whenever IMAX®
content is played. If you wish to keep the Dirac Live Bass Control correction or your own Bass Management setup, please select “User profile” so your Bass Management remains unchanged.
System Setup
To control the ISP using the iPad StormRemote App or Control Systems via TCP/IP, the Network should remain active at all times.

ISP Immersive Sound Processor

· Network standby: Enable the Network Standby (On) to allow for control via IP when in Standby. Note that the standby consumption will be higher.
· Enable fast boot: this mode will substantially decrease power on time of the ISP at the expense of greater standby power consumption.
Front Panel
Settings that govern behavior of the front panel screen.
· Active Brightness: Brightness of the screen when the screen is actively being used.
· Standby Brightness: Brightness of the screen when not actively being used.
· Standby Timeout: Length of time elapsed between active use of screen and reduction of brightness to standby level.
· Zoom on Changes: When ON, changes made via remote control (input, volume, etc.) will temporarily be shown in a large type so these changes can easily be read from across the room.
Triggers
The ISP has 4 independent DC voltage triggers which can be configured to modulate the power/ standby status of connected equipment such as projectors, source components, or amplifiers.

You may keep the default name for each trigger, or rename them to something more descriptive.
Each trigger has the following options available:
· Manual Switching: Turn on to enable a button on the remote control interfaces that allows a user to toggle the trigger manually.
· Auto Switching: “Enabled on Wake” activates the trigger when the ISP is powered on from standby. It will not automatically deactivate the trigger when the ISP is placed into standby. “Enabled on Input” makes the trigger available in the Input Menu. When set to Y for an input, the trigger activates when that input is selected from a remote interface. See “9. Triggers” on page 17. “Enabled on Preset” makes the trigger available in the Preset menu. When a preset is selected in which a trigger is marked Y, the trigger is activated. Note that Auto Switching trigger behavior will override any Manual Switching behavior.
· Disabled on Sleep: Select Y if the trigger should deactivate when the ISP is placed into standby.
· Active State: Select whether the active state for the trigger is 12V or 0V.
· Delay: You may wish to set a delay of up to 8 seconds. Usually this is done if you are using triggers to activate multiple amplifiers. If all amplifiers power on at once, the inrush current could trip a circuit breaker. StormAudio amplifier triggers may be daisy chained so that only once the preceding amplifier is fully powered does the following amplifier initiate it’s power up sequence thereby obviating the need for a delay (or multiple triggers) when using modern StormAudio amplifiers.
Audio/Video General Delay per AV Zone
Set the global lip sync delay for each theater, A/V, and Headphone zone here. Max value is 250 ms.

In case of Multichannel Theaters linked to HDMI Out 1, it is possible to use the Auto Lipsync feature that will automatically adjust the optimal delay including the display system delay. This only works with compatible device.

· IMAX Mode: The ISP is IMAX® Enhanced certified and can render IMAX® Enhanced optimised content. To enable IMAX® Enhanced, select “Auto”. Whenever a content is flagged IMAX®
Enhanced, the decoder will automatically render the stream properly with all required postprocessing. Turning it “OFF” will always disregard
IMAX® Enhanced specific content.
· DTS Dialog Norm: With some DTS soundtrack, a dialog normalization level might have been defined to allow for proper channels level alignments. Select “On” to automatically apply this when detetced. When “Off” this feature will be bypassed.
· Center Spread: When the Dolby Surround preferred upmix is selected, you can decide to activate the Center Spread function. When “Off”, dialog are mostly reproduced by the Center channel. When “On”, dialog will also be reproduced by the L/R speakers. Usually, “On” is appropriate for Music content upmix, while “Off” is more adequate for Movies or TV playback.
6. Triggers
Any triggers configured for Manual Switching (see “Triggers” on page 39) will have a button available here. Clicking one of these buttons will toggle the trigger and therefore the connected device.
7. Temporary Audio Adjustments
Even though you may have meticulously calibrated the theater in Main Speakers settings, some material may sound best with slight adjustments. Adjustments here are temporary and reset to 0 with each change of Preset.
· Center Enhance: Adjust the level of the center channel between -6 and +6dB in 1dB increments.
· Surround Enhance: Adjust the level of the surround channels between -6 and +6dB in 1dB increments.
· Sub Enhance: Adjust the level of the subwoofer channels between -6 and +6dB in 1dB increments.
· Bass: Tone control to adjust the bass level in the entire theater using both the subwoofer and main channels between -6 and +6dB in 1dB increments.
· Treble: Tone control to adjust the treble level in the entire theater between -6 and +6dB in 1dB increments.
· Brightness: Tilt the tonal balance of the presentation towards darker timbre (negative figures) or brighter timber (positive figures).
42

· Lipsync: Temporarily adjust lip sync delay to accommodate some sources. Note that this is also reset every time a new input is selected, so if you find yourself regularly setting this to the same figure, adjust the delay either per source (“8. AV Delay” on page 17) or for the entire theater (“Audio/Video General Delay per AV Zone” on page 39).
8. Zone2 Control
Within the configuration for each preset, you may select auxillary zones which may be enabled. If zones are enabled for the currently selected preset, you may choose them from the dropdown menu and individually adjust volume, bass, treble, EQ (except for Downmix zone), mute for each A/V and Headphone zones, also include a temporary lipsync adjustment.
A secondary input can be selected for the Zone2 auxiliary audio zones (8c), different from the Main Theater input. For each Zone it is possible to then select either the Secondary Zone2 source or the source currently playing in the Main Theater (8b).
9. HDMI Pass Through
When the HDMI Matrix mode has been set to Pass Through (see “HDMI” on page 36), a new source selector will become visible in the remote control page. All sources defined with a HDMI path will be available for selection and routing to the second HDMI output port.
Independent Remote Control
The IR control unit operates effectively within a distance of 23 feet (7 meters) and an angle of 30° from the processor. Using the control near fluorescent lights may shorten this range, as will any dust or dirt that accumulates on the front of the remote control or the remote-sensor area of the processor. Also, avoid blocking the line of sight between processor and remote.
Install the two supplied AAA batteries in the remote as shown. Be certain to follow the (+) and (­) polarity indicators that are on the top of the battery compartment.

Wiring Recommendations 1. XLR pin out
To connect the ISP to an amplifier, you must use male to female XLR cables. The connector in the ISP is a Male XLR. We recommend up to 3m cables.
2. XLR to RCA unbalancing cable
In some cases, it might be required to connect to ampliers with unbalanced inputs. In such case, the wiring should be done as shown.
3. AES/EBU RJ45 connector pin out
The Multichannel Digital Inputs and Outputs options use RJ45 cables to carry the AES/EBU signals. The pinout of the RJ45 connectors on the ISP is described herewith with the corresponding XLR connector wiring.
4. USB ports
There are two USB ports available used for StormMonitoring microphone connection and USB upgrade when no network access is available. The 2x ports can be used to provide 5V power supply in the limit of 500mA maximum total consumption for the two ports.
