INSTALLATION  
To.ensure.years.of.enjoyment.from.your.NADY.AUDIO..  
MM-15USB.mixer,.please.read.and.understand.this.manual.  
thoroughly.before.using.the.unit.  
1. INSPECTION  
Your.NADY.AUDIO.MM-15USB.was.carefully.packed.at.the.  
factory.in.packaging.designed.to.protect.the.units.in.shipment..  
Before.installing.and.using.your.unit,.carefully.examine.the.  
packaging.and.all.contents.for.any.signs.of.physical.damage.that.  
may.have.occurred.in.transit.  
[Please note: Nady Systems is not responsible for shipping  
damage. If your unit is damaged, do not return to Nady, but  
notify your dealer and the shipping company (if shipped to you)  
immediately to make a claim. Such claims must be made by the  
consignee in a timely manner].  
ꢀ. POWER CONNECTION  
The.MM-15USB.is.designed.to.operate.with.the.supplied  
external.power.adapter..Please.make.sure.that  
the.adapter.supplied.is.marked.for.the.correct.voltage  
in.your.area.(120VAC/60.Hz.or.230VAC/50Hz)..Power  
requirements.for.electrical.equipment.differ.from.area.to  
area..In.new.installations.and.portable.sound.systems,.or  
any.situation.in.which.the.AC.power.is.in.question,.it.is  
wise.to.confirm.the.voltage.and.use.the.appropriate  
power.adapter.unit.before.connecting.it.to.power.sources.  
Check.to.see.that.the.power.adapter..is.set.to.the.voltage.for.your  
area.by.referring.to.the.table.below:  
Europe.(except.UK):.230V,.50Hz  
UK.and.Australia:.240V,.50Hz  
USA.and.Canada:.120V,.60.Hz  
For.other.areas,.please.check.with.local.authorities.  
.
When.ready.to.operate,.connect.the.switched-off.MM-15USB.and.  
power.adapter.first,.then.plug.the.adapter.to.a.power.source.or.  
wall.outlet..Make.sure.that.the.unit.is.turned.off.before.connecting.  
to.the.AC.power.source.to.avoid.possible.loud.transients,.which.  
can.damage.your.speakers.or.your.ears..Set.the.Main Level(21).  
fader.control.to.minimum.to.further.reduce.the.chance.of.  
undesired.noise.when.first.powering.up..Turn.on.your.MM-15USB.  
using.the.rear.panel.ON/OFF.switch.

(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.(-).  
(ꢀ) LINE INPUT  
This.14.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.14.TRS.(stereo).phone.plug.should.be.wired.for:..  
Tip.=.positive.(+),.Ring.=.negative.(-),.Sleeve.=.ground..  
Unbalanced.signals.should.use.a.typical.¼”.TS.plug.

for.reducing.floor.rumble,.popping,.breathing.noises,.woolly.

(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.

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.

(ꢁ) EQUALIZER CONTROLS  
(10) PRE-FADER TO RECORD SWITCH  
All.channels.are.fitted.with.a.three-band.EQ.-.HIGH,.MID,.and.  
LOW..All.three.bands.have.up.to.15.dB.of.cut.and.boost,.with.a.  
center.detent.for.OFF..The.frequency.response.is.flat.when.all.  
three.EQ.knobs.are.in.the.center.detent.position..The.HIGH.and.  
LOW.shelving.controls.have.their.frequencies.fixed.at.10KHz.  
and.80Hz.respectively..The.MID.control.has.a.peaking.response.  
at.2KHz..The.channel.EQ.is.a.valuable.feature.of.the.mixer.as.it.  
Enabling.this.switch.will.route.the.input.signal.of.the.channel.to.the.  
Record Outputs(30)..The.signal.will.be.post-EQ.and.pre.channel.  
level.control.  
(11) CHANNEL 3/4 & 5/ꢁ STEREO INPUTS  
These.14.and.RCA.unbalanced.inputs.are.designed.to.accept.  
line.level.signals.such.as.those.common.to.CD/tape.players,.  
allows.the.user.to.control.the.tonal.characteristics.of.each.channel. keyboards,.direct.outputs.and.home.stereo.or.DJ.equipment..  
separately..For.example,.boosting.the.LOW.can.fatten.the.sound,.  
add.warmth.to.vocals,.or.extra.punch.to.bass,.drums.and.synths;.  
the.MID.control.can.be.used.to.define.the.midrange.or.bring.out.  
the.vocals;.and.adjusting.the.HIGH.control.can.provide.a.crisp.  
sounding.high.end..Another.very.important,.yet.often.overlooked.  
technique.is.to.use.the.EQ.to.subtract.from.the.mix..Cutting.the.  
HIGH.control.can.reduce.unwanted.sibilance,.hiss,.cymbals,.  
or.high.frequency.feedback,.while.attenuating.the.MID.or.LOW.  
can.also.eliminate.feedback.or.clear.up.a.muddy.sounding.mix..  
Cutting.the.HIGH.and.LOW,.then.pushing.up.the.Channel Level  
Control(6).is.equivalent.to.mid.range.boost!.  
The.14.inputs.can.also.be.used.as.standard.mono.line.inputs.by.  
plugging.into.the.L.input.only..This.signal.will.be.routed.equally.to.  
the.Pan.control.and.the.left.and.right.outputs.in.the.same.way.as.  
the.standard.line.input.channels..  
For.each.channel.there.are.separate.A.and.B.stereo.inputs..Using.  
both.sets.of.inputs.simultaneously.can.cause.some.level.issues,.  
which.may.require.the.volume.of.the.preceding.equipment.to.be.  
adjusted..The.“A”.1/4”.inputs.are.always.enabled..To.utilize.the.“B”.  
RCA.inputs,.the.B Enable Switch(12).must.be.depressed..This.  
allows.the.user.to.switch.on.the.B.input.source.instantaneously..  
[Note: Always check the channel’s Peak LED Indicator(5) after  
(1ꢀ) B ENABLE SWITCH  
altering the amount of equalization].  
Depressing.this.switch.will.turn.on.the.B.Inputs.of.channels.3/4.  
and.5/6.  
The.key.to.successful.equalization.is.to.avoid.excess..Too.  
much.equalization.on.the.input.channels.will.result.in.a.mix.that.  
is.smeared.together.with.nothing.specifically.defined..During.  
rehearsals,.experiment.with.the.equalizer.controls.on.various.  
instruments,.vocals.and.combinations.of.these.mixed.together.to.  
become.familiar.with.various.equalizer.settings.  
(7) AUX SEND CONTROL  
This.control.adjusts.the.level.of.signal.sent.to.the.Aux Send(23).  
output..The.channel.Aux.Send.control.is.mono,.post-EQ,.and.  
post-Level.control.meaning.the.signal.level.sent.to.the.Aux.bus.will.  
also.be.affected.by.the.Channel Level(9).setting..  
(8) PAN  
The.channel.Pan.positions.the.output.of.the.channel.in.the.  
left/right.stereo.field.of.the.Main.mix..Its.constant-power.design.  
ensures.there.are.no.level.discrepancies.whether.a.signal.is.hard-  
panned,.center-stage,.or.somewhere.in-between..For.channels.34  
.
and.56.this.acts.as.a.balance.control.
