•RCA inputs are connected to both left and right channels

•Signal Input Switch selected to Unbalanced for RCA input

•Left Phase Switch set to 0°

•Right Phase Switch set to 180°

• Inverting the right signal will allow the bridged woofer to operate correctly

•Gain for left and right channels set equally to balance the subwoofer

•Impedance for bridged channel should be 2Ω minimum

•XCard is in High-Pass,Low-Pass or Full Range position
