three-band EQ with

+15 dB of boost/cut with
a semi-parametric mid sweepable from 250
– 5,000 Hz. These channels shall have pre­fade listen (PFL), a mute switch and a 60­mm fader. All input channels will have four
aux sends. Auxs 1 and 2 are fixed pre-fader
and auxs 3 and 4 are fixed post-fader.

The master section shall have four aux mas­ter sends, each with an LED overload indi­cator and after-fade listen (AFL). There shall
be two stereo, mono-compatible aux returns
