SAFETY PRECAUTION

Please read the instructions before attempting to install or operate this equipment. Please keep the following in mind as you unpack and install this equipment:

• Always follow basic safety precautions to reduce the risk of fire, electrical shock, and injury.
• To prevent fire or shock hazards, do not expose the unit to rain, or moisture or install this product near water.
• Never spill liquid of any kind on or into this product.
• Where possible, install the audio matrix towards the top of the rack to avoid the unit overheating.
• Only use the supplied IEC cable.
• Never push any objects into this product through any openings or empty slots in the unit as you may damage parts inside and/or cause an electrical shock.
• Do not allow anything to rest on the power cabling and avoid putting the weight of any kind on it.
• To protect the unit from overheating do not block any vents or openings in the unit housing that provides ventilation. Allow sufficient space for air to circulate around the unit.
• This product is intended for use in a clean (dust-free) residential environment.

Ventilation

• It’s important to keep the product well ventilated when installing this Pulse-Eight ProAudio.
• Any electronic equipment will generate heat. A well-ventilated area helps to disperse the heat. If placed in a poorly ventilated area, your equipment may heat up and cause irreparable damage to the circuitries.
• Allowing systems to run for prolonged periods under high temperatures will break down circuitry and electrical component. It also applies if the device is left in the path of direct sunlight or near any heat source.
• Dust tends to accumulate and will disrupt the fan and electronics system. Dust particles contain various compositions like water, oil, and other minerals or chemicals. Having them in your electronic device can sometimes cause a signal error or degradation to the internal chips and circuitries. Because we cannot accurately predict how or when they can affect your device, we highly recommend that you keep Pulse-Eight products not only in a well-ventilated area but also as clean as possible.
• In some cases, insects or reptiles can make nests near or inside the electronic casing. Whilst we design our products to maximize the protection of internal electronics, please be aware that insects and reptiles can be drawn to these types of habitats. In the unlikely event, this does happen, this will lead to poor ventilation inside the unit, and it will be unable to disperse heat effectively.
• Finally, whenever possible, do not stack audio and video matrixes together. Leave enough space in between each unit in order to provide good airflow.

FCC Warning

• This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

OVERVIEW – AUDIO ROUTING CAPABILITIES

• The ProAudio1632 DSP Pre-Amp Audio Matrix features 40 audio inputs (16x Stereo L/R, 8x Optical, 16x Digital Coax) and 32 audio zone outputs (32 Stereo L/R and 32 Digital Coax). Any audio input can be routed to any audio output, including digital to analog conversion. Audio downmix (multi-channel to stereo conversion) is not supported.
• Note that Analog to Digital conversion is only supported when the digital output port is set to mirror its respective analog output port.
• The diagram below described the basic audio routing capabilities of the ProAudio1632.
• • Only digital 2-channel PCM -to- analog (stereo) conversion is supported. Multichannel downmix is not supported.

IMPORTANT: Outputs can be treated separately or paired together. When paired, analog output 1 is paired with digital output 1, 2 to 2, 3 to 3, etc. By default, analog outputs will be mirrored on the digital coax sides.

INSTALLATION

1. The ProAudio1632 features up to 40 independent audio inputs. Connect your audio source devices directly to the inputs accordingly.

2. The ProAudio1632 can have between 32 to 64 audio output zones, depending on your configuration. Connect your audio outputs to the relevant AVR or Audio amplifiers. IMPORTANT: If your installation required certain analog input to be converted and routed to digital (coax output), then you will need to mirror the corresponding analog stereo output to do so.

3. Please refer to OVERVIEW – AUDIO ROUTING CAPABILITIES section for more information.

4. Connect either the Serial (RS232) or Ethernet connection to your controller.
   Ethernet Connection (recommended): Connect to the local Ethernet using the ProAudio’s TCP/IP port. Serial Connection: Connect a serial cable between the controller and the ProAudio’s RS232 port.

5. Connect the power using the included IEC cable.

6. The unit will take 15-30 seconds to boot up and get an IP address, if using the Ethernet port. Note: After boot up, please check the LEDs on the front of the system, as described on the PANEL DESCRIPTIONS section.

7. Link to third-party control system.
   Access the Pulse-Eight Cloud Monitoring site to download the necessary drivers. Follow the installation instructions in the driver documentation for that control system.

8. Alternatively, if you do not have a third-party control system (or driver is not available), please refer to the Control Setup section.

WIRING DIAGRAM Example of ProAudio1632 wiring with a video matrix (e.g. neoX+) and an amplifier (e.g. ProAmp8).

CONTROL SETUP

• ProAudio can be configured using third-party controllers such as Control4, ELAN, and Savant. On the back of the unit, there is an ID button that allows you to configure it directly with Control4. For more information please download the relevant driver and documentation from the Pulse-Eight Cloud Monitoring.
• Alternatively, ProAudio also provides a direct configuration method via Command Line Interface (CLI). To use CLI, connect directly to the RS232 port OR use an Ethernet cable with the other end connected to a computer, preferably one running Windows and with access to its communication ports.

Configuring Using Command Line Interface

• If you are not using a third-party control system, you can control the ProAudio product with your favourite terminal programme.
• PuTTY, for example, is a well-known open source terminal programme. You may already have a copy of this programme on your PC; if not, it can be downloaded at: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
• Please refer to the ProAudio Universal Protocol Guide.

Using The Serial Port
To use a serial port, you must have a USB to Serial port straight through cable. The ProAudio has a female RS-232 connector, but the USB cable connector must have male pins. When a USB cable is plugged in, Windows will assign a COM port. Determine the COM port of the USB cable using Windows’ Device Manager. It’s usually between COM3 and COM6, but it can be any number Windows chooses. Then follow these steps:

1. Choose ‘Serial’ as the Connection type.
2. Then, enter the COM port at the Serial line.
3. The baud rate is 19200. Enter the baud rate at the Speed.
4. After setting up the COM port and baud rate click on ‘Terminal’.
5.  Go to the “Setting Up The Line Control Option” section, as this is required.

Using TCP/IP
To use TCP/IP, you must first search the network for the IP address of the ProAudio. Depending on when the ProAudio was made, the MAC address will be listed under Zektor or Pulse-Eight.
The MAC address will either begin with 5C.D4.AB.xx.xx.xx or 00-15-82-xx-xx-xx.

Once the IP address is known. Then follow these steps:

1. Choose ‘Raw’ as the Connection type.
2.  Then, enter the IP address/MAC address at the Host Name.
3. Enter the 50005 at the Port.
4. After entering the IP address and port number click on “Terminal”. Then, go to the “Setting Up The Line Control Option” section, as this is required. Setting Up The Line Control Options
5. Set them to “Force on” this allows you to see what you are typing, and to edit it before sending.
6. After the two options are selected, press the “open” button, and the command window should open up. Testing The Connection
7. To see if a connection has been established, enter the version command: ^V$ and then press enter. The terminal program being used (e.g. PuTTY), will then send the response showing the model switch that is connected as shown in the image. The unit should report back the following:

• , ,
• Please note that the internal serial number should not be used for support queries.
• For more information, including list of API commands, please refer to the ProAudio Universal Protocol Guide.

PAGING AND DOORBELL

The back panel can be wired to accept dry contact closures (for push buttons or relay triggers), or voltage triggers. You can mix connection types and setup one connection for dry closures, and the other for voltage triggers .

• To use dry contact closures, add a jumper between the SE and dB connections, and connect the switch to other dB input and the SW input. Note that the SW-1 and SW-2 connections are also connected to the chassis ground. If you are using a shielded cable to the switch, connect the SW side to the shield. If one side of your button is grounded, the side that is grounded should use the SW connection.
• The voltage trigger inputs can be wired directly to the doorbell transformer, so that when the doorbell rings, paging will also occur. When used in this manner, the doorbell system can be setup to mute or lower the volume of the audio during a doorbell press, to allow the doorbell to be heard.

HOW DO I SETUP THE PAGING SYSTEM?

• When a page or doorbell is triggered (from now on just referred to as a “page”), all the zones switch to a predetermined source, and a predetermined volume. When the page is finished, all the zones are restored to their normal operation.
• There are two page settings, with their own setups. For instance ‘page 1’ could be used for the front door, and ‘page 2’ for the back door. If you have two different sound generators, then you could have a different sound for the two doorbells, and setup the pages to be connected to two different sources.
• To make all this work, the installers need to set up, in advance, all the things each zone should do when a page is triggered. This can be done by sending the correct commands over the serial or TCP/IP port.
• Please refer to your control driver documentation or please refer to the ProAudio Universal Protocol Guide, depending on your control setup.

AUDIO OUTPUT ZONE SETTINGS

The ProAudio1632 offers several parameters that can be individually set for each output port (zone). The following parameters can be adjusted per output port:

• Volume: Range from +24dB to -99.5dB, and full mute (-115dB), in 0.5dB step resolutions.
• Balance: Range from -200 (full left) to +200 (full right) in 0.5 dB steps.
• Treble: Range from -20dB to +20dB, in 0.5dB steps
• 5-Band Equalizer: Set at 100Hz, 330Hz, 1,000Hz, 3,300Hz and 10,000Hz. Each EQ band setting can range from -20dB to +20db, in 0.5dB steps.
• Stereo to Mono Mix : If required, the stereo inputs can be mixed in a number of ways.
• Lock Zone: It can be set so that the selected audio output to be locked to another zone.
• Subwoofer Settings (Filter/Frequency): When using a subwoofer, you can set the sub filter to 12dB or 24dB, and the sub crossover frequency to be anything between 50-300Hz.
• Lip Sync: Can set a delay to the output. Range between 0-170.65 ms, in 1/48 ms steps.
• Coax Port: Enable the Coax port to mirror the stereo (analog) port, or to be independent.
• 12V Trigger: Assign any of the available trigger ports to be paired the selected audio output port.
• Paging Settings: Set actions that each zone should take when a page.

For more information, please refer to “CONFIGURE PROAUDIO OUTPUTS” section on your control driver documentation. Alternatively, refer to the ProAudio Universal Protocol Guide when not using a third-party control system.

LOCK ZONE

• The ProAudio1632 has “Zone Lock” capabilities for all of its audio outputs.
• The Zone Lock feature allows you to:
  • Make an audio output zone always switch to the same source as a different output zone
  • Send volume to one output zone and have another zone go to the same volume
  • Or, when using a subwoofer, it can make the subwoofer (connected to the audio output zone) switch to the same source as the smaller speakers
• Every audio output has a “Lock Zone” parameter that can be set to follow another zone.
• For instance, if you have a set of stereo speakers connected to output 1 (zone 1), and a subwoofer connected to output 2 (zone 2), then you would set zone 2 to use “Lock Zone’ parameter to lock it to output 1. Now each time zone 1 changes sources, zone 2 will also change sources. When the volume is raised on zone 1, zone 2’s volume will also be raised.
• More than one zone can be locked onto the same zone. For instance, after the above zone is setup (i.e. zone 2 is locked to zone 1), then Audio Output 3 (zone 3) can be set to lock to zone 1. Now each time zone 1 changes sources, both zones 2 and 3 will also change sources. When the volume is raised on zone 1, then the volume for zones 2 & 3 will also be raised.

Please note that not all things are locked between the outputs, here’s the list of locked parameters:

• Volume (including other volume related parameters like Mute)
• Bass and Treble (but not the equalizers)
• Source changes
• Anything not listed above, is not locked. Notable things are that are not locked are:
  • Equalizers, this allows using different setting for a subwoofer than for the stereo set.
  • Output Level, this allows adjusting the level of a subwoofer independent of the stereo speakers.
  • Lip Sync Delay, this allows a delay to be set to compensate for distances between the subwoofer and speakers.

Caveats:

• Care must be taken to avoid a zone following itself; for example, if zone 2 and zone 3 follow zone 1, but zone 1 follows zone 3, this will not work because zone 1 is following itself. Zone 1 in this example cannot be followed by any other zone.
• If you accidentally set a zone to follow itself, all zones that follow it will revert to the unlock mode.
• For more information, please refer to your control driver documentation.

SETTING UP A SUBWOOFER

• Each zone has a crossover filter that can allow only high frequencies, or only low frequencies to pass, or be disabled (and allow all frequencies to pass).
• Both the crossover type and the crossover frequency has to be set before the crossover filter is enabled. This can be done by selecting the correct “crossover filter” parameter for both the subwoofer and main speaker zone outputs.

Note:

• The default is to set “24dB/oct Low Pass Filter” for the subwoofer zone and “24dB/oct High Pass Filter” for the main stereo speakers zone.
• The 12dB / 24dB is the sharpness of the filter, how fast it cuts off high or low frequencies. Experimenting with this setting and listening for what sounds best is encouraged.
• Then the “crossover frequency” parameter are to be set for both the subwoofer and main speaker zone outputs.
• Note: Both the main speakers and the subwoofer should be set to the same frequency. When going up in frequency, this setting indicates the frequency the subwoofer stops working and the main speakers take over. This value is usually between 100Hz and 150Hz, but we allow values between 50 and 300Hz.
• Again, experimenting with this setting and listening for what sounds best is encouraged. For more information, please refer to your control driver documentation.

SETTING MINIMUM/MAXIMUM VOLUME

• The output’s “min volume” and “max volume” settings are the absolute volume levels. A volume level of 0 means that the signal level coming into the switch is the same as the signal level going out.
• Each step of one of the settings is a 0.5dB change. So a setting of 1 = +0.5dB gain, and -1 = -0.5dB loss.
• So the default values are 24 = 12.0dB gain, and -120 = -60dB loss.
• The gain command is given in 0.5dB steps and uses an offset of 200 to indicate a gain of 0.0dB. Values above 200 raise gain, and values below 200 lower gain.
• The minimum and maximum volume settings must have at least a 49.5dB (99 steps) difference between them. Any attempt to set the maximum volume closer than 99 steps of the minimum, will result in a setting of exactly 99 steps above the minimum volume setting.
• The use of the Max Volume is pretty straight forward. Any user of the switch cannot set the level above Max Volume, this can be used to limit volumes at specific zones.
• The Min Volume use is more subtle. If you are in a quiet room, you can turn down the volume and still hear audio way down into whisper levels. In a case like this you would set the Min Volume to a large negative value, since this will allow you to turn the volume way down.
• If you have speakers in the backyard, you might not hear much once you turn the speakers below 50% because of all the background noise, this is irritating because now half the volume is wasted, once you get below 50% nothing happens. And if the volume level starts all the way down at 1%, it can feel like it’s not working as you hold the volume button down between 1% and 49%, waiting to hear something. In this case like this, you can turn the Min Volume up until you can actually start to hear something at around 5% or so. Now you have the complete range of the volume control from 1% to 100%, and the sound fades out below 5% like it should.
• For more information, please refer to your control driver documentation.

FIXED AUDIO OUTPUT

• There might be occasions when the volume control on the switch needs to be disabled, such as when using an AVR as an amplifier.
• To do so, select the Audio Output of the zone you’re interested in setting up, then set the volume to 84%. Note that 84% is the pass through level (if the Min and Max default volume settings have not been changed). It sets the volume so that the level going out is the same as the level coming in.
• To keep the volume from changing, make sure you don’t use the audio switch as the volume endpoint for the zone being setup. In the AVR example, the AVR should be the volume endpoint, not the audio switch.

TROUBLESHOOTING

Should you encounter installation difficulties or issues with device communication, the following checklist of common issues and causes should help resolve your issues. If you still continue to experience issues, please contact your local representative or Customer Support team (cs@pulse- eight.com) for further assistance.

No Audio

• Cable quality and condition – cable/connectors can easily be damaged and the quality of material can vary. Always use good quality leads and cables and try swapping cables that are known to be working into the solution to see if this improves your output.
• Volume – check that the selected audio output is not set to full mute or a very low volume.
• Amplifier – confirm that the connected audio amplifier and speakers are working as expected.
• Output routing and settings – make sure that the audio output is routed to the desired audio input.
• Digital output – when using the coax output, please ensure that the attached AVR/amplifier supports 5.1/3.1 multichannel audio and 2ch PCM audio.

“Paging” Not Triggering

• When setting up the paging it is important to ensure that the dry contacts or triggers are wired up correctly. Please check against the wiring shown in the PAGING AND DOORBELL section.
• Have you set up the specified output port “paging” settings on your control system correctly? As each output port needs to be set up individually, it is important to ensure that if any issues arise, that the settings are double-checked as it is easy to make a mistake when setting several of the outputs to support paging functionality.

Subwoofer Not Working
Have you set the subwoofer output port correctly? It is important that the output port for the subwoofer is LOCKED to the output port that the stereo speaker (Front-Left/Front-Right) are connected to. Check that the crossover frequency is set to between 100Hz and 150Hz to begin with for testing. See SETTING UP SUBWOOFER section.

Hear A Low “Humming/Buzzing Noise”
On the rare occasion when there might be a low, humming or buzzing noise coming from the speakers in your installation, the causes could be poor cabling, other equipment in the setup (e.g. amplifier), possible “ground loop” feedback noise on the RCA cables or on the AC mains.

• First, check that the cables are all of good quality and maybe consider replacing them if you notice that they have an effect.
• Secondly, verify that the amplifier and speakers do not cause this humming noise on their own when disconnected from the ProAudio.
• If neither of the above resolves the issue, then the problem might be “ground loop” noise and it is worth consider replacing the standard RCA connectors (from ProAudio to amplifier) with a “ground isolator” adapter RCA cable. It is also worthwhile considering adding an isolating transformer or a “DC blocker” on the AC power input of the equipment.

WARRANTY TERMS & CONDITIONS

IMPORTANT INFORMATION ABOUT YOUR RIGHTS AND OBLIGATIONS, AS WELL AS LIMITATIONS AND EXCLUSIONS THAT MAY APPLY TO YOU. YOUR RIGHTS AND THIS LIMITED WARRANTY
This Limited Warranty gives you specific legal rights. You may also have other legal rights that vary by state, province, or jurisdiction. The disclaimers, exclusions, and limitations of liability under this Limited Warranty will not apply to the extent prohibited by applicable law. For a full description of your legal rights, you should refer to the laws applicable in your jurisdiction and you may wish to contact a relevant consumer advisory service.

1. WHAT THIS LIMITED WARRANTY COVERS; PERIOD OF COVERAGE

2. Pulse-Eight Limited (“Pulse-Eight”), 8-12 Alder Hills, Poole, BH12 4AL, UK, warrants to the owner of the enclosed product that the product contained in this box (“Product”) will be free from defects in materials and workmanship for a period of three years from the date of delivery following the original purchase (the “Warranty Period”), or if this product has been professionally installed, the warranty start date is from the date your installer purchased the item, not your system commissioning date. Please check with your installer for their purchase date. If the Product fails to conform to this Limited Warranty during the Warranty Period, Pulse-Eight will, at its sole discretion, either (a) repair or replace any defective Product or component; or (b) accept the return of the Product and refund within 45 days of return the money actually paid by the original purchaser for the Product. Repair or replacement may be made with a new or refurbished product or components, at Pulse-Eight’s sole discretion.

3. If the Product or a component incorporated within it is no longer available, Pulse-Eight may replace the Product with a similar product of similar function, at Pulse-Eight’s sole discretion. This is your sole and exclusive remedy for breach of this Limited Warranty. Any Product that has either been repaired or replaced under this Limited Warranty will be covered by the terms of this Limited Warranty for the longer of ninety (90) days from the date of delivery or the remaining Warranty Period. This Limited Warranty is transferable from the original purchaser to subsequent owners, but the Warranty Period will not be extended in duration or expanded in coverage for any such transfer.

4. TOTAL SATISFACTION RETURN POLICY
   If you are the original purchaser of the Product and you are not satisfied with this product for any reason, you may return it in its original condition within thirty (30) days of the original purchase and receive a full refund. If this is a professionally installed product, you must check with your installer regarding their own returns policy.

5. WARRANTY CONDITIONS; HOW TO GET SERVICE IF YOU WANT TO CLAIM UNDER THIS LIMITED WARRANTY
   Before being able to claim under this Limited Warranty, the owner of the Product must (a) notify Pulse-Eight of the intention to claim by emailing support@pulse-eight.com during the Warranty Period and providing a description of the alleged failure, and (b) comply with Pulse-Eight’s return shipping instructions, and (c) ship the Product at owner’s cost (except where prohibited by applicable law) to Pulse-Eight for repair or replacement. Pulse-Eight will have no warranty obligations with respect to a returned Product if it determines, in its reasonable discretion after examination of the returned Product that the Product is an Ineligible Product (defined below). Pulse-Eight will bear all costs of return shipping to the owner, except with respect to any Ineligible Product, for which the owner will bear all shipping costs.

6. WHAT THIS LIMITED WARRANTY DOES NOT COVER
   This warranty does not cover the following (collectively “Ineligible Products”): Products marked as “sample” or sold “AS IS”; or Products that have been subject to: (a) modifications, alterations, tampering, or improper maintenance or repairs; (b) handling, storage, installation, testing, or use not in accordance with the Installation Guide or other instructions provided by Pulse-Eight; (c) abuse or misuse of the Product; (d) breakdowns, fluctuations, or interruptions in electric power or the telecommunications network; or (e) Acts of God, including lightning, fire, flood, tornado, earthquake, or hurricane. This warranty does not cover consumable parts, including batteries unless damage is due to defects in materials or workmanship of the Product, or software (even if packaged or sold with the product). Pulse-Eight recommends that you use only authorized service providers for maintenance or repair. Unauthorized use of the Product or software can impair the Product’s performance and may invalidate this Limited Warranty. Pulse-Eight does not warrant that operation of the Product will be error-free or uninterrupted or that the Product will in every case process all data correctly.

7. DISCLAIMER OF WARRANTIES
   Except as stated above in this limited warranty, and to the maximum extent permitted by applicable law, Pulse-Eight disclaims all express, implied, and statutory warranties and conditions with respect to the product, including the implied warranties of merchantability, fitness for a particular purpose. To the maximum extent permitted by applicable law, also limits the duration of any implied warranties or conditions to the duration of this limited warranty.

8. LIMITATION OF DAMAGES
   In addition to the above warranty disclaimers, in no event will Pulse-Eight be liable for any consequential, incidental, exemplary, or special damages, including any damages for lost data or lost profits, arising from or relating to this limited warranty or the product, and Pulse-Eight’s total cumulative liability arising from or related to this limited warranty or the product will not exceed the amount actually paid for the product by the original purchaser.

9. LIMITATION OF LIABILITY
   Pulse-Eight disclaims all liability of any kind of Pulse-Eight’s suppliers. The Pulse-Eight online services (“services”) may provide you with information (“product information”) regarding your product’s performance and/or peripherals connected to your product (“product peripherals”). The type of product peripherals that may be connected to your product may change from time to time. Without limiting the generality of the disclaimers above, all product information is provided for your convenience, “as is”, and “as available”. Pulse-eight does not represent, warrant, or guarantee that product information will be available, accurate, or reliable. You use all product information, the services, and the product at your own discretion and at risk. You will be solely responsible for (and Pulse-Eight disclaims) any and all loss, liability, or damages, including to your HVAC system, plumbing, home, product, product peripherals, computer, mobile device, and all other items and pets in your home, resulting from your use of the product information, services, or product. The product information provided by the services is not intended as a substitute for direct means of obtaining the information.

10. VARIATIONS THAT MIGHT APPLY TO THIS LIMITED WARRANTY
