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
