(1) MIC INPUT
This.electronically.balanced.XLR.input.is.designed.to.accept.
signals.from.any.balanced.or.unbalanced.low.impedance.(Low.Z).
microphone..The.XLR.jack.is.configured.for:.Pin1.=.ground,..
Pin2.=.positive.(+),.Pin3.=.negative.(-).

”.input.is.designed.to.accept.balanced.or.unbalanced.line-

level.signals.such.as.those.from.keyboards,.drum.machines,.or.
samplers..If.a.balanced.signal.is.to.be.connected.to.the.line.input,.
then.a.

”.TRS.(stereo).phone.plug.should.be.wired.for:..

Tip.=.positive.(+),.Ring.=.negative.(-),.Sleeve.=.ground..
Unbalanced.signals.should.use.a.typical.¼”.TS.plug.

(3) LOW CUT FILTER
Use.this.Low-Cut.(high-pass).filter.(18.dB/octave,.-3.dB.at.110Hz).
for.reducing.floor.rumble,.popping,.breathing.noises,.woolly.
bottom.end,.and.to.tighten.up.channels.in.a.mix,.etc..It.is.most.
effective.when.used.carefully.in.conjunction.with.the.Equalizer 
Controls(6).

(4) GAIN CONTROL
The.Gain.control.adjusts.the.input.sensitivity.of.the.mic.and.
line.inputs.on.each.channel..This.control.can.be.adjusted.to.
accommodate.input.signals.from.a.wide.variety.of.sources,.from.
the.high.outputs.of.keyboards.or.drum.machines.to.the.small.
signal.outputs.of.microphones..The.best.balance.of.S/N.and.
dynamic.range.will.be.achieved.if.you.adjust.the.Gain.control.on.
each.channel.separately.so.that.the.maximum.level.signal.can.
be.input.without.distortion..While.speaking,.singing,.or.playing.
an.instrument.at.maximum.performance.level,.increase.the.Gain.
control.until.the.Peak LED(5).flashes,.then.turn.down.the.Gain.
control.until.the.flashing.stops.

(5) PEAK LED INDICATOR
The.Peak.LED.illuminates.when.a.channel.input.is.overloading..
It.detects.the.peak.level.after.the.Equalizer Controls(6).and.will.
light.just.before.clipping.to.warn.that.the.signal.is.approaching.
overload..You.do.not.want.the.Peak.LED.to.light.except.very.
intermittently..If.it.lights.persistently,.reduce.the.Gain Control(4).
