Bridged Mode Output
XPA 4002 bridged mono output speaker wiring
In bridged mode, the output mode toggle switch for Input 1 must be set to the bridged (up)
position (see figure 8 below).
For Input 1: The channel 1 + output terminal becomes the b output terminal and
the channel 2 + output terminal becomes the bridged “-” output terminal (see figure 14).
