General Description
output has a balanced, low impedance, transformer-isolated, XLR connector, and an
input detects excessive inputs and helps avoid clipping. A p an control on each input

The input trim varies the gain of the pre-amplifier stage of each input channel, providing a
The high control in each input channel alters th e frequency response of t he channel input,
having flat audio response at the detented "0" position.
This control assigns the fader output signal of the channel to the Program L, R mixing busses.

The graphic equalizer is normally used for either the PGM or FB mix. For normal operation, only one
button should be pressed. If the equalizer is not being used, the "OFF" button should be depressed.
