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 bridged mode. When Mono is selected the inputs are summed and when in stereo the inputs remain independent to pro- vide a stereo output. See Bridged Operation pg6 for further details.

Rack Mounting: The DPA-4.8 amplifier can be rack mounted. The amplifier will take 3 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 four will be illuminated when the zone is in the active mode. When the zone is mute or inactive the LED will not be illuminated.

Speaker Outputs: 4-ohm or 8-ohm speakers can be connected. For Bridge amplifier operation, con- nect the + of the speaker to the R+ of the amplifi- er and - of the speaker to the L+ of the amplifier.

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 amplifier zone into standby mode after the preset period of time.
