1. Power Switch
To.turn.the.equalizer.ON.or.OFF,.press.the.upper.or.lower.portion.of.
this.button..The.internal.LED.indicator.will.light.when.the.unit.is.on..
CAUTION: Always turn on your equalizer BEFORE your power
amplifiers are turned on, and always turn off your equalizer
AFTER your power amplifiers have been turned off to avoid any
turn on/off transient noise.
. Gain Control
The.Gain.control.allows.adjustment.between.OFF.(center.
detent).and.+/-12dB..This.control.is.used.to.adjust.for.variation.
in.input.level.to.the.equalizer.channel,.or.to.compensate.for.
the.equalization.applied.to.the.input.signal..Unity.gain.can.be.
achieved.by.setting.this.control.to.its.center.detent.position..The.
unit.is.equipped.with.a.red.Peak.LED,.which.illuminates.when.the.
signal.reaches.3dB.prior.to.clipping..It.is.acceptable.for.the.Peak.
LED.to.flash.occasionally,.however,.if.the.Peak.LED.is.flashing.
steadily,.the.Gain.control.should.be.reduced.to.avoid.distortion..
3. Low-Cut Filter
This switch enables a low cut filter at 40Hz, 12dB/octave to
remove.unwanted.low.frequencies.from.the.signal.to.prevent.
stage.rumble.and.low.frequency.resonance.that.can.occur.while.
using.speakers.in.an.enclosed.acoustic.environment..The.LED.
status.indicator.will.light.yellow.when.the.Low.Cut.is.enabled..
4. EQ ON/OFF
This.switch.enables.or.bypasses.the.equalizer.filters..If.you.
disable.the.EQ.ON/OFF.switch,.the.LED.will.turn.off.and.the.unit.
will.be.in.bypass.mode..In.bypass.mode,.the.audio.signal.will.flow.
through.without.any.equalization.although.the.Gain.control.will.still.
be.active..
5. Output Level LED Bargraph
This.four-stage.LED.bargraph.illuminates.according.to.the.output.
signal.level..The.red.Peak.LED.lights.at.3dB.prior.to.clipping..
Occasional.blinking.of.the.Peak.LED.is.acceptable,.but.if.it.
remains.on.more.than.intermittently.you.should.turn.down.either.
the.equalizer’s.level.controls.or.reduce.the.input.Gain.level..
6. Filter Level Slider Controls
Each.one.of.these.linear.potentiometers.will.boost.or.cut.its.noted.
frequency.by.+/-12dB..When.all.of.the.sliders.are.in.center.detent.
position,.the.output.of.the.equalizer.is.flat..Each.slider.is.marked.
with.the.center.frequency.of.its.band.pass.filter..
