ARCHITECTURE MIXER
Before we begin to use the controls and sliders in the
mixer, you should have a basic knowledge of the components of
the mixer and the signal ow between the various components.
Without those basics, you might give the impression that some
controls operate incorrectly or not work: there may be another
tight control to a position inconsistent.
Apartfromthat,therearesometermsthatshouldfamiliarizethemselves
with,andtobeusedrepeatedlythroughoutthisusermanual.
CHANNELS
Achannelisamixersectionthatprocessesasingleaudiosignal.
Giventhatthemixerhastwochannels.Despitesignsthatbothchannels
enteringthesamemixer,remainseparateintheirrespectivechannels,
allowingprocessindependentlybeforemixinginonechannel:the
Audience.
GAIN
Whenasignalofanaudiochannelentersamixer,therstthingyoudo
isgothroughthegaincontrol.

Thiscontrolincreasesordecreasesthevolumeofincomingaudio
signal,asaresultofwhichmayincreasethevolumeofsongscasualties
orreducethelevelofthehighest.Thisisanessentialsteptomaintaina
highqualityaudioandbalancethelevelsoftwosongstomix.
EQUALIZER CONTROLS
Then,inthesignalchainistheequalizer,orinshort,theEQ.Ifthegain
controlincreasesordecreasestheleveloftheentireaudiosignal
channel,theEQincreasesortemperslevelofaspecicfrequency
rangeoftheaudiosignal.

Thismixerallowsyoutocontrolthelevelranges(orbands)different
frequency,calledHigh,LowandMid(acute,mediaandsevere)and
theirrespectiveprot.
ItislikelythattheequalizeristhemostpowerfulweaponofaDJmixer
(althoughsomepeoplethinkit’sthecrossfader).
TheEQcontrolsareusedto:
1.-Toimprovethesoundqualityofsomebadsongsproducedor
recorded.
2.-Tohelpbalancetheoverallfrequencycontentoftwosongs.
3.-Emphasizemusicremovingorisolatingoneormorefrequency
bands.
4.-Mixsongssuperimposingthefrequencybandsoftwosongsthat
soundatonce.

ENGLISH
ENGLISH-06
Theoldsongsdonotusuallyhavesomanyseriousastoday.Itisoften
usedoftenEQserioustoamplifylow(frequenciessevere)anoldsong
andlevelingitsgravewithamodern.Failuretodosomaygivethe
impressionthat,whenmovingfromonesongatarecentancientmusic
soundslower.
Likewise,eventhesongsrecordedinthesameyearmaysound
differentfromoneanother,yetdespitereproducethesamevolume.This
effectisusuallyduetooneofthemhassomewaysmorepronounced
thantheother.Ifthegraveofbothsongsseemtosoundthesame
volume,youcanusetheEQmeansto“lowervolume”thesongthat
soundsevenstrongerbalancewiththesongweaker.
Also,DJsalsoliketoplayontheirperformancesintheiropinionby
manipulatingthesongsthatcapture.Forexample,aDJthatcancutthe
frequencyofsevereacuteandatrackafewbarsbeforethechorusofa
song,andthenrecoverthemattherighttimeinstartingthechorus.
Whenplayingtwosongsatthesametime,itiscommonthatthe
musicsoundcloudy.Thiseffectisusuallyduetoanincompatibilityof
thetwoserioussongs.Thereasonmaybethattonalityofthetwosongs
isdifferent,orthatbothsongshaveseriouslongandsustainednotes.
Tosolvethisproblemandgainclarity,lowenoughtoeliminateoneof
thesongs.
Themixturewillretainthegraveofanothersong,sowewillcontinue
soundingnatural.

ENGLISH-07
LISTENED WITH EARPHONES
AfterthesignalpassingthroughtheEQ,issenttotwodifferent
destinations.Oneconcernstheheadphones,whichmeanslistening
anaudiosignalwithoutbeingaffectedbythefadervolume(insome
mixersthisfeatureiscalled“Cue”).
Ifyou’renotfamiliarwithusingamixer,thisdenitiondoesnotseemto
makesense.However,thinkofitasifitwereawaytolistentomusic
privately-channelmixer,regardlessofwhattheylistentotheaudience.
CUE
ThecontrolCueservestoestablishapointof‘cue’inasong.Acueisa
pointofreferencepositionwithinthesongtowhichyoucanjump
instantlyratherthanhavingtogotondtherunway.
Normally,inaccordancewithDJscuepointsatthebeginningofatime
ofthesong.

FADERS VOLUME CHANNEL
Besidessenttothesectionofheadphones,theaudiocomesfromthe
EQalsosendsthevolumefaderchannel.
Thisisthevolumecontrolofthemainchannel(thoughitissubjectto
crossfader).Theycanmatchthevolumesoftwotracks.
However,someDJsprefertokeepthevolumefaderschannelatits
highestpositionandadjustthevolumeofsongsthroughtheGain
controls.Thereasonforthischoiceisthatallowsthemtousethese
fadersforotherpurposesasmoltenvolume,choppycutsoreffects
similartothetechniquesemployedwiththecrossfader.Decanterby
eithermethodisamatterofpersonalpreference.
Youcanusethevolumeslidertoadjustthevolumefaderchannel
CROSSFADER
Theaudiosignal,afterleavingtheindividualchannelsthroughthemixer
volumefaderchannel,issenttothesideofthecrossfaderitsshare.
Asyoucansee,hernameisveryappropriate,sinceitallowsconduct
afadingbetweenthetwochannelswithamovementfromsidetoside
mixer.

ENGLISH
ENGLISH-09
Whenthecrossfaderisinitscentralposition,hearthetwochannels
mixer.IfyoumovethecrossfadertotallyleftaloneheartheChannel1.
Ifyoumovethecrossfaderfullyclockwise,onlyheartheChannel2
ThecrossfaderwasinventedtoprovideDJsaneasywaytoaccomplish
withonehandmeltedoffasongandotherinput,andthetruthisthat
fullsitsroleperfectly.However,sinceitsintroduction,DJshave
transformedthissimpletoolintoapowerfulweaponthatenables
extremelyfastcuts,scratches,andmanyothertechniques.
