Bridged Mode operation requires the speaker wires to be
connected across a single, different terminal on each channel (A+
and B-) (see Figure 1).
(Figure 2) 2-Channel Wiring
If 2-Channel Mode is used, then Channel A is connected to the
A+ and A- terminals and B channel is connected to the B+ and B-
terminals (see Figure 2).
