board and painted steel chassis. It has six 1/4" stereo headphone outputs, one 1/
4" TRS stereo input located on the front panel. Right and Left 1/4" Input jacks, and
six 1/4" Insert jacks are located on the rear panel. There are two Auxiliary Inputs
(right and left) located on the rear panel. Each channel has a Volume control,
panning and balance is controlled via the Pan control located on the front panel,
and the unit features a MONO/STEREO switch.
