When the amplifier is in Bridged mode operation, both the left and right
channels are combined for a higher power mono output.
For bridged amplifier operation, turn off the power to the amplifier and connect
an 8-ohm minimum load to the Speaker B output.
Following the Bridge mode markings in red on the back of the amplifier:
Connect the negative lead (-) of the speaker cable to the R+ terminal. Connect
the positive lead (+) of the speaker cable to the L+ terminal. Set the Stereo/Bridge
Mono switch to Bridge Mono, connect the Line In feed from a source to the Left
Line In connection and restore power to the amplifier.
