Cable Wiring Diagram for Balanced Send / Return Jacks
The
Send Jack
on the back panel of the M80 routes the signal being processed by the channel to
outboard devices or to recording media.
Left and Right XLR Auxiliary Inputs
are available for routing stereo signals into the
Stereo Mix Bus. The Aux Inputs can be used to introduce a stereo single such as the output of a stereo
tape machine to the Stereo Mix Bus of the M80. The various input signals of the individual channels of the
M80 can then be mixed with the introduced stereo signal by using the PAN controls located on the
individual channels.
These
Aux Bus Inputs
can be used to combine the outputs of multiple M80’s. The M80’s can be
cascaded by connecting the Stereo Mix Bus Outputs the Aux inputs of the next M80 in line. The
combined signal to the XLR Stereo Mix Bus outputs of the last M80 in the signal chain becomes the
master output of the cascaded M80’s.
