Stereo reverse
This mode is similar to the Tandem mono mode except that by operating channel A and B in
opposite polarity the energy storage in the power supply is more efficient. This means that
the amplifier can deliver up to 10% more power than in tandem mono mode (a significant
advantage for signals below 100 Hz such as sub bass etc).
For stereo reverse operation, depress the Phase reverse switch so that Channel B is phase
reversed. To compensate,
connect pin +1 on the Channel B Speakon to the speaker's
negative terminal and pin -1 on Channel B to the speaker's positive terminal.
Alternatively, connect pin +2 on the channel A Speakon to the negative speaker
terminal and pin –2 on Channel A to the positive speaker terminal.

Channel A output is connected as in the normal stereo mode.
