Bridge CHC/CHD
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. In real life some
technical issues avoid that the output power increase that much. Please refer to the technical specification at page 25.
The disadvantage of the bridge mode is a lowest speaker impedance of 4 Ohm. The usage of 2 Ohm can cause unproper work
and technical damage.
