Operate PSA Professional Stereo Amplifiers in Parallel Mode
In this mode, the channel A input signal will be output from the output connectors of
both channels. The channel B input jack is not used; the channel A and channel B
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 B input you can use this socket to "daisy
chain" the signal to another amplifier.
