The sliders are 20mm center detent with a selectable boost/cut range, and the unit provides balanced and unbalanced input and output connections, fixed high pass and low pass filters, variable input level controls, clip level indicators, a ground lift switch, along with an internal universal power supply.

The unit has EQ bypass switches for each channel with LED status indicators, and is housed in a rugged, all-steel 2U rack space chassis.
