5.3.6 Bridged mono operation
The STEREO/MONO switch is located behind slot #2 of the standard input module (see
Figure 31). For bridged mono operation, move the STEREO/MONO switch all the way to the
right to the BRIDGED setting. Connect the input signal to CH 2 input (CH 1 input becomes
disabled).
Outputs:
Jumper the Commons (COM) on both CH 1 and CH 2. Next, connect the negative (–) to the
desired setting CH 1 output and positive (+) to the same setting on the CH 2 output.
When connected in this way, each channel "sees" half the impedance of the speaker
connected between them.
Note: Be sure to set both input level controls to exactly the same setting for equal power
distribution per channel.
In high-impedance bridged mono operation, the amplifier will yield the following results:
