Channel 3 Signal Sense: If no signal is present at the Channel 4 input, the signal connected to the Channel 3
input will be routed to both the Channel 3 and Channel 4 outputs.
ZXSUM8 Remote: The remote provides
level control of the output of Channel 4.
As shown in the installation diagrams, we
recommend always using Channel 4 as your
subwoofer channel so that you can control
the bass level with this remote. When the
AUX-IN switch is depressed the Aux-In LED
will illuminate, and the ZXSUM8 source will
be switched from the high-level inputs to the
low-level AUX input.
