Operate MAC 2 series in Parallel Mode
In this mode, the channel 1 input signal will be output from the output connectors
of both channels. The channel 2 input jack is not used; the channel 1 and channel 2
volumes can be adjusted independently. Use the Parallel Mode when you want to
drive two speakers with only one input signal keeping separate control of the volume
of the two channels.
NOTE: since you are not using the channel 2 input you can use this socket to
"daisy-chain" the signal to another amplifier.
