Speaker Outputs
: The A and B speaker outputs are in parallel to the amplifier output. When connected to the A or
B output either 4-ohm or 8-ohm speakers could be connected. When using both A and B speaker outputs, only 8-
ohm speakers can be connected, and this will result in a 4-ohm load at the amplifier. For Bridge amplifier opera-
tion, connect the + of the speaker to the R+ of the amplifier and - of the speaker to the L+ of the amplifer.
12 Volt Trigger In and Out
: The Trigger output is 12 volts at a maximum of 150ma.
This can be used to drive a relay-operated AC outlet or other 12 volt triggered
devices. The 12-volt trigger input is used to activate a zone independent from the
auto turn on sensing circuit. The delay and audio sensing are bypassed when the
12 volt trigger input is used.
Muting Delay Time
: Muting delay can be adjusted from about 2 minutes to 10 minutes. When an
audio signal is not present, this delay setting will automatically put the amplifiers into standby
mode after the preset period of time.
Power
: Two heavy-duty 500va toroidal transformers power the DPA-6.12. Each
transformer has three taps to power 3 stereo zones, totaling six taps for the six
stereo outputs. The voltage setting for the AC input is set at the factory for opera-
tion of either 110 VAC 60Hz or 240 VAC 50Hz. Please reference the voltage rating
on the back panel. Includes detachable 3 terminal power cord.
