4. FRONT PANEL
Rack Mounting
: The DPA-6.12 amplifier can be rack mounted. The amplifier will take four rack spaces.
Power Switch
: Turns on the main power for the amplifier. When the power is on the LED will be illuminated.
Zone Indicator LEDs
: Zone one to six will be illuminated when the zone is in the active mode. When the zone is
mute or inactive the LED will not be illuminated.
5. BACK PANEL CONNECTIONS
Main Bus Input / Output
: This is used when the input audio signal will be used
by more than one zone. The output is to loop out to another DPA-6.12 or other
amplifiers.
Line Input
: The line audio input at each zone is the left and right dedicated input for that zone.
This is a sensing input that will activate the zone when an audio signal is present. When there is
no audio the zone will go into standby.
Bus / Line Switch
: Selects the Line audio input or the Main bus input for each
zone. When the Bus is selected the zone will amplify the audio on the Main
Bus input. When line is selected the zone will amplify the audio at the line
input for that zone.
Gain Controls
: Left and Right gain controls adjust independently the sound level for each channel.
When used in the bridge mode only the right control is used.
Stereo / Mono Switch
: This selects stereo or mono for the speaker outputs. In
the Mono position each Left and Right output is Mono. The Mono selection will
also be used to select operation for bridge mode. When Mono is selected the
inputs are summed and when in stereo the inputs remain independent to pro-
vide a stereo output.
