Operate MAC 2 series in Bridged Mode
In this mode, the channel 1 input signal will be output from the bridge output
connectors. ( The 2 RED binding post ) In this case, use the channel 1 volume
control to adjust the volume, keep the volume control of channel 2 turned completely
down ( counter clockwise ). Bridged mode is intended for driving loads with a total
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.
