CONFIGURATION MODES
STEREO MULTIZONE MODE
In this conguration, the Analog Stereo Inputs are mapped one-to-one with the Speaker Zone
Outputs. There will be 8-zone stereo inputs routed to 8-zone stereo outputs.
During installation, a range of congurations can be set, including the min/max volume range and
enabling a bridge-mode output per zone.
The Dolby Audio Input Port is disabled and not used in this mode.
DOLBY MULTICHANNEL MODE
In this mode, the Dolby Digital Port input will be active and capable of accepting Dolby Digital 5.1
which will be mapped to 6-surround sound output channels.
Note: In Dolby Multi-channel mode, stereo multi-zone inputs 1, 2 and 3 are disabled.
The Speaker Outputs zones are assigned according to the two sub-modes of operation in Dolby Multi-
channel Mode:
Dolby 3-zone (and 5 stereo zones):
- Zone 1: Front Right (FR) and Front Left (FL) channels
- Zone 2: Rear Right (RR) and Rear Left (RL) channels
- Zone 3: Center (assigned to Left output) and Passive Subwoofer (assigned to Right).
- Zone 4-8: Mapped one-to-one to Analog Stereo Inputs 4-8.
Dolby 4-zone (and 4 stereo zones):
- Zone 1: Front Right (FR) and Front Left (FL) channels
- Zone 2: Rear Right (RR) and Rear Left (RL) channels
- Zone 3: Center (assigned to Left output)
- Zone 4: Bridged Subwoofer
- Zone 5-8: Mapped one-to-one to Analog Stereo Inputs 5-8.
Dolby 4-zone setting is only required for Dolby Multi-channel Mode setups requiring a bridged output
for passive subwoofer. However, this requires an extra speaker zone output (zone 4) from the amplier.
The Active Subwoofer Output is always enabled in any of the Dolby Multi-channel Mode settings.
Enabling Stereo PCM Upmix will ensure that any 2-channel audio input on the Dolby Input will
automatically be converted to 5.1 channel so that there is an audio output on all home-theatre
surround sound outputs.

POWER MODES
The ProAmp8 can manually congure each of its output zones to be turned on/o individually. Also,
it is possible to set an automatic power-saving operation for each zone output, either to Auto-sense
mode or 12V trigger mode.
AUTOSENSE MODE
The ProAmp8 will detect when there is no audio signal (below an assignable dB threshold) on its
analog input within a time period, and it will automatically turn OFF the corresponding Speaker Zone.
Both the input threshold and time period can be congured within the WebUI.
Auto-sense currently is not supported on the Dolby Digital Input.
12V TRIGGER MODE
Each of the assigned Speaker Zone Outputs will only turn ON when a 12V signal is present on the 12V
Trigger Input jack.
Note: 12V Trigger is only connected via a 3.5mm termination.
Both Auto-sense and 12V Trigger Mode have an incredibly fast wake-up time from standby (under 1
second) for the audio zone to turn on; ideal for time-critical applications.

SETUP GUIDE
INSTALLING THE 8ZONE POWER AMPLIFIER IN A RACK
1. Attach the rack ears to the front sides of the amplier using the provided screws.
2. Install into rack and connect cabling according to mode of operation – as described below.
WARNING: To prevent damage, it is important to ensure adequate ventilation space on the sides
of the amplier, especially on the ventilation openings on the side of the product enclosure.
3. For Stereo Multi-zone Mode setup, go to step 4.
For Home-Theater Multi-channel Mode setup, go to step 9.
CONNECTING THE PROAMP8 ANALOG AUDIO INPUTS
4. Connect audio cables to the Analog Stereo Inputs (1-8) RCA inputs. See diagram.
Note: In Stereo Multi-Zone Mode, the ProAmp8 Amplier accepts stereo line-level audio
connections to all its 8-zone analog audio inputs jacks (Analog Stereo Inputs). Each zone input will
pass amplied audio to the respective Speaker Zone Outputs.
CONNECTING THE PROAMP8 OUTPUTS TO SPEAKERS
5. Remove the speaker connectors.
Note: The ProAmp8 can power eight stereo zones of audio and has phoenix-style terminal blocks
for speaker connections.
6. For non-bridged outputs: Connect speakers to the speaker connector and insert into the ProAmp8
respective Speaker Zone Outputs. See diagram
