Page 25: Bridge Mode Function
9.) SYSTEM SETUP 9.8) Bridge Mode Function The SQ series allows to set CHA/CHB and/or CHC/CHD into bridge mode. In this mode the input signal CHA and/or CHC will be internal inverted and used for the cooperating amplifier channel. The result at the output is a signal with twice the voltage of a single output in stereo or parallel mode. For the output power it means that double voltage could theoretically increase the output power 4 times. -
