Slide the bridging switch in the direction of the arrow to bridge two adjacent amplifier channels. Set the controls of the newly bridged pair by using the EVEN numbered channel.
When two channels are bridged together, connect speakers to the two terminals labeled “Bridged”.

STEP | DESCRIPTION |
1.Choose which of the six pairs you wish to bridge and move the bridging switch for that pair to the “Bridged” position (toward arrow).
The 12 channels are grouped into 6 pairs (e.g. 1 & 2). Only the two channels within a pair can be bridged. Thus, only channels 1 and 2, or channels 3 and 4 could be bridged. You cannot bridge 2 and 3 for example.

3.Use the EVEN NUMBERED input, DIP switch, and level control for connections and configuration.
When two channels are bridged into one, make sure that the odd numbered input DIP switches are all in the “off” position.
