PA-600 AMPLIFIER OPERATION

The following diagrams are excerpts from the system block diagrams and are intended to provide a simplified view of the operating modes of the amplifier.

BRIDGE MONO SWITCH: This switch connects the channels to work together for more power output. With the switch in "MONO" Mode the amplifier is in the Bridge Mono Mode. In the Bridge Mono Mode, connect input to Channel 1 (Channel 2's inputs are disconnected). Both amp channel are internally bridged together to create a single-channel amplifier of increased output power.

Use the two red BINDING POSTS (labeled " M o n o / B i a m p " ) o r p i n s 1 + / 2 + o f t h e BIAMP/MONO (middle) Phone jack.
