  • 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 weight of any kind on it.
  • To protect the unit from overheating do not block any vents or openings in the unit housing that provide 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 components. 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. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna.
  • Increase the separation between the equipment and the receiver.
  • Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.

OVERVIEW – AUDIO ROUTING CAPABILITIES

The ProAudio3248 DSP Pre-Amp Audio Matrix features 80 audio inputs (32x Stereo L/R, 16x Optical, 32x Digital Coax) and 48 audio zone outputs (48 Stereo L/R and 48 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 describes the basic audio routing capabilities of the ProAudio3248. Only digital 2-channel PCM-to-analog (stereo) conversion is supported. Multichannel downmix is not supported.

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 the 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 favorite terminal program.
PuTTY, for example, is a well-known open-source terminal program. You may already have a copy of this program on your PC; if not, it can be downloaded at: https://www.chiark.greenend.org.uk/ 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:

PULSE-EIGHT-ProAudio-3248-DSP-Pre-Amp-Audio-Matrix-FIG-

  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
  6. 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.

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 set up 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 the 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 set up to mute or lower the volume of the audio during a doorbell press, to allow the doorbell to be heard.

HOW DO I SET UP 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.

PULSE-EIGHT-ProAudio-3248-DSP-Pre-Amp-Audio-Matrix-FIG-
\(14\)
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 ProAudio3248 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 +20 dB 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 is 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: This can set a delay to the output. The 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 with the selected audio output port.
  • Paging Settings: Set actions that each zone should take when a page.

For more information, please refer to the “CONFIGURE PRO AUDIO 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 ProAudio3248 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 the “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 in zone 1, zone 2’s volume will also be raised. More than one zone can be locked into the same zone. For instance, after the above zone is set (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 in 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 that are not locked are:

  • Equalizers allow the use of different settings 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 have 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 is 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 0.0 dB. 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 straightforward. 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, 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% as 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 set. 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) is connected to. Check that the crossover frequency is set to between 100Hz and 150Hz, to begin with for testing. See the 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 considering 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.

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.

If the Product or a component incorporated within it is no longer available, Pulse-Eight may replace the Product with a similar product of a 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.
