In this mode, the channel A input signal will be output from the bridge output
Connectors (The 2 RED binding post). In this case, use the channel A volume
control to adjust the volume, keep the volume control of channel B turned completely

impedance of 4 ohms or greater. In Bridge Mode you will combine the power of
both channels into one speaker. You will have available massive amount of power
so check carefully the power handling of your speaker before operation.
