Getting Started — ProAudio

Modified on Tue, 28 Apr at 5:41 PM

This guide is for installers who are new to the Pulse-Eight ProAudio range. ProAudio is a DSP audio matrix — it takes multiple audio sources and distributes them to multiple independent zones, with per-zone volume, EQ, and tone control. All configuration is done through the ProAudio Config Tool, a Windows application that connects to the unit over the network.


Before You Start

Which model do you have?

Check the label on the front panel. The ProAudio range runs from the ProAudio8 (8 zones, 2U) up to the ProAudio3264 (64 zones, 6U). The model name tells you the zone count — a ProAudio16 has 16 output zones, a ProAudio1632 has 16 inputs and 32 output zones, and so on. For a full model comparison see ProAudio Range — Which Model Do I Need?

ProAudio is not the same product as ProAmp. The ProAudio is a DSP audio matrix — it routes and processes audio but does not amplify it. The ProAmp8 is a separate power amplifier. In most installations they are used together: ProAudio handles routing and DSP, ProAmp handles amplification. Keep them clearly separated in your documentation and labelling.

What you need before starting

  • A Windows PC or laptop on the same network as the ProAudio unit
  • The ProAudio Config Tool — download from pulse-eight.com
  • A network switch with a spare port
  • RCA phono cables or digital coax / optical cables for sources and zone outputs
  • A power amplifier per zone (or the ProAmp8 for up to 8 zones)

Understanding inputs and outputs

Each ProAudio input channel has three physical connectors: stereo L/R (analogue RCA), optical (TOSLINK), and digital coax. These are three alternative ways to connect the same source — you use whichever format your source device outputs. Only one connection per input channel is active at a time; the unit detects the active signal automatically.

Each output zone has stereo L/R analogue outputs and digital coax outputs. Connect the zone output to your amplifier's input. If you are using the ProAmp8, connect the ProAudio zone output to the corresponding ProAmp8 input.


Step-by-Step: First Install

1
Rack the unit and connect power
Mount the ProAudio in the rack. The 2U models (ProAudio8, 16, 16RS) are rear-heavy — support the rear during installation. Connect the IEC power cable. Do not power on yet.
2
Connect audio sources to the inputs
Connect your source devices to the input channels on the rear panel using RCA phono (stereo L/R), optical, or digital coax — whichever the source supports. Label each input as you go. Inputs are numbered on the rear panel.
3
Connect zone outputs to amplifiers
Connect the stereo L/R output for each zone to the corresponding amplifier input. If using the ProAmp8, connect ProAudio zone 1 output to ProAmp8 input 1, zone 2 to input 2, and so on. The ProAmp8 sits below the ProAudio in the rack in most installations.
4
Connect doorbell / paging inputs if required
The ProAudio has 2 dedicated paging/doorbell inputs. These accept an analogue signal from a doorbell chime unit or paging microphone. When a signal is present on a paging input, it can be configured to override or mix into selected zones. Connect paging hardware now if it is part of the installation.
5
Connect the ProAudio to the network
Plug a Cat cable from the ProAudio's Ethernet port into your network switch. The unit uses DHCP by default. Make sure your Windows PC is on the same network.
6
Power on
Power on the ProAudio (and ProAmp8 if present). The front panel LEDs will illuminate. Allow 30 seconds for the unit to fully boot and appear on the network.
7
Install and open the ProAudio Config Tool

Download and install the ProAudio Config Tool on your Windows PC. Open the Config Tool — it will automatically scan the network and display any ProAudio units it finds. Click on your unit to connect.

If the unit does not appear, confirm the PC and ProAudio are on the same network segment. You can also enter the IP address manually. See ProAudio Not Showing up on Network if the unit cannot be found.


8
Back up the factory configuration

Before making any changes, use the Config Tool to save the factory default configuration. Go to File>Save Configuration. 
This gives you a restore point if anything goes wrong during setup. See 
9
Set up gain staging

Gain staging is the most important step before configuring anything else. Incorrect gain staging is the root cause of most audio quality issues — noise, distortion, and poor dynamic range. Set input gains so that nominal signal level from each source reads at 0dB on the input meters in the Config Tool. Do not clip the inputs. See ProAudio Gain Staging for the full process.


10
Configure zone routing
In the Config Tool, assign which source plays to which zone. Each zone can play any source independently. Test each zone by routing a known-good source and confirming audio at the speakers.


11
Set minimum and maximum volume per zone
Go to each zone's settings and configure the minimum and maximum volume limits. This prevents zones from being turned all the way off (if required) or driven too loud. 
12
Configure EQ per zone if required
The ProAudio has a 5-band parametric EQ per output zone. Configure EQ to compensate for room acoustics or speaker characteristics. 
13
Configure paging if required
If the installation includes a doorbell or paging system, configure the paging inputs in the Config Tool — set which zones the paging signal overrides, at what level, and whether it mixes or ducks the background audio. 
14
Assign a static IP
Go to Network Settings in the Config Tool and assign a static IP address to the ProAudio. This is required for control system integration. 
15
Save the final configuration
Once all zones are configured, save the configuration to disk and also write it to the unit. Keep the saved configuration file — if the unit is ever reset or replaced, you can restore the full setup in minutes.

First Install Checklist

  • Unit racked and powered on
  • All audio sources connected to input channels
  • All zone outputs connected to amplifiers
  • Paging / doorbell inputs connected (if applicable)
  • ProAudio visible in Config Tool
  • Factory configuration backed up
  • Gain staging completed — no inputs clipping
  • Zone routing configured and tested — audio confirmed at each zone
  • Min/max volume limits set per zone
  • EQ configured per zone (if required)
  • Paging configured and tested (if applicable)
  • Static IP assigned and noted for control system
  • Final configuration saved to disk and written to unit
  • Control system driver loaded and tested

Common First-Install Issues

ProAudio not appearing in Config Tool

Confirm the PC and ProAudio are on the same network segment. Check the front panel — if the network LED is not lit, check the Ethernet cable and switch port. If the unit is on the network but the Config Tool still does not find it, try entering the IP address manually. The IP can be found in your router's DHCP client list. See ProAudio Not on Network.

No audio in a zone

Work through in order: confirm the source is active and a signal is present on the input meter in Config Tool, confirm routing is set correctly for that zone, confirm the zone volume is not at zero, confirm the amplifier is powered and the speaker connections are correct. If the input meter shows no signal, the problem is upstream of the ProAudio. If the meter shows signal but no audio at the zone output, check the zone routing and output gain settings. See ProAudio Zone No Audio.

Audio is noisy or distorted

This is almost always a gain staging issue. If input gain is set too high, the signal clips internally. If it is set too low, you compensate with high output gain and amplify the noise floor. Redo gain staging from scratch. See ProAudio Gain Staging.

Source volume levels are uneven between zones

Each source will have a slightly different output level. Use the input gain control per channel to normalise levels so all sources play at a consistent volume when set to the same zone level. This is part of the gain staging process.
