BRIDGING OPERATION
Asnly amplxfiers are in tue bridging mode when both the MONO switch and
BRIDGING switch are depressed. In this mode, the channel one input feeds both
sides of the amp, but the phase of the channel two amplifier is inverted 180
degrees, so that the two amplifiers' outputs are out of phase. The speaker
connection is then made to the two RED output jacks, as shown in Figure 8.
The black output jacks are not used.
