The mixer shall have (12 or 16) input chan-
nels with top-mounted input and output con-
nectors.
The input channels shall have a 3-pin XLR-
type connector with universal phantom
power and a balanced ¼-inch high-imped-
ance line input. These channels will have a
three-band EQwith +15dB ofboost/cut with
a semi-parametric mid sweepable from 250
– 5,000 Hz. These channels shall have pre-
fade listen (PFL), a mute switch and a 60-
mm 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 mas-
ter sends, each with an LED overload indi-
catorand after-fade listen (AFL). Thereshall
be two stereo, mono-compatible aux returns
with level and balance controls. There shall
be two 10-segment LED meters that can
monitor either the master outputs or the
mono/PFL signals. There shall be separate
recordoutput and tape playback controlsand
a headphone amplifier with a gain control.
Themaster outputsandthe monooutput shall
be controlled with 60-mm faders and have
mute switches.
