Typical Set-Up
NADY.AUDIO.graphic.equalizers.may.be.used.wherever.modifi-
cation.of.the.frequency.contour.of.a.sound.system.is.needed..A.
graphic.equalizer.is.a.solution.to.any.number.of.sound.problems.
or.creative.urges..
SOUND REINFORCEMENT APPLICATIONS
By.routing.the.signal.from.the.mixer.to.the.main.power.amplifiers.
(or.crossover),.the.overall.frequency.of.the.mix.may.be.altered.to.
do.a.number.of.things..
Through.the.use.of.a.real-time.audio.spectrum.analyzer,.a.
calibrated.microphone,.and.a.pink.noise.source,.the.audio.
system.may.be.“TUNED”.to.make.the.overall.audio.spectrum.
response.of.the.audio.reinforcement.system.and.the.room.
environment flatter in its frequency response.
By.turning.up.the.audio.reinforcement.system.to.the.
feedback.point,.then.attenuating.the.oscillating.frequency.
(1/3.octave.resolution),.then.turning.the.system.up.to.
attenuate.the.2nd.oscillating.frequency,.and.then.the.3rd,.
and.so.on,.you.can.enable.the.entire.audio.system.to.have.
much.more.gain.before.feedback..
Amplifiers and speakers may be protected by the use of
the.LOW.CUT.feature.of.the.equalizer..Wind.noise.or.the.
loud.percussive.sound.of.dropped.microphones,.etc.,.could.
potentially.cause.damage.to.the.amps.and/or.speakers..By.
rolling.off.the.extreme.LOW.frequencies.with.the.LOW.CUT.
filter, a measure of protection is added to the system without
severely.affecting.the.overall.sound.quality..
In.noisy.environments,.the.audio.signal.may.be.tailored.for.
better.intelligibility.and.penetration..This.is.especially.useful.
for.public.address.systems..
Creative.use.of.the.equalizer.allows.shaping.of.the.signal.for.
a.more.pleasing.sound.or.for.special.effects..The.only.limits.
are.those.of.taste.and.imagination..
MUSICAL INSTRUMENT APPLICATIONS
Putting.an.equalizer.in.line.with.a.musical.instrument.allows.
you.to.modify.the.sound.of.the.instrument..You.can.brighten.
the.sound,.or.add.body.to.a.thin.sounding.instrument,.or.
even.give.the.sound.a.totally.different.character..
An.equalizer.will.allow.you.to.eliminate.unwanted.sounds,.
like a 60-cycle HUM from a badly grounded amplifier.
STUDIO APPLICATIONS
A.graphic.equalizer.is.one.of.the.most.useful.tools.in.the.sound.

engineer’s.bag..NADY.AUDIO.equalizers.offer.the.features.and.
flexibility.to.perform.where.it.counts.in.the.studio..
Fix.a.track.that.doesn’t.sound.quite.right..Put.the.equalizer.in.
an.effects.send.and.return.it.to.the.MIX.bus..
Create an artificial stereo by splitting a monaural signal and
equalizing.the.split.signals.differently,.then.panning.one.
equalized.signal.to.the.right.and.the.other.signal.to.the.left..
Shape.the.sound.by.changing.the.frequency.response.of.the.
track..
Special.effects,.like.a.telephone.sound,.can.be.created.by.
cutting off the LOW end to 200Hz and the HIGH end to
6KHz.
