Constant Loudness ! ! !

The1642VLZ4’spancontrolsemployadesign

called“ConstantLoudness.”Ithasnothingto

dowithlivingnexttoafreeway.Asyouturn

thepanknobfromlefttoright(therebycausingthe

soundtomovefromthelefttothecentertotheright),

thesoundwillappeartoremainatthesamevolume

(orloudness).

Ifyouhaveachannelpannedhardleft(orright)and

reading0dB,itmustdipdownabout4dBontheleft

(orright)whenpannedcenter.Todootherwise,like

thoseBrandXmixers,wouldmakethesoundappear

muchlouderwhenpannedcenter.

32. 3-Band Mid-Sweep EQ

Theeightmonochannelshavea3-band,

mid-sweepequalization:lowshelvingat80

Hz,midsweeppeakingfrom100Hzto8kHz,

andhishelvingat12kHz.It’sprobablyallthe

EQyou’lleverneed!(Shelvingmeansthatthe

circuitryboostsorcutsallfrequenciespast

thespeciedfrequency.Forexample,the

1642VLZ4’slowEQboostsbassfrequencies

below80Hzandcontinuingdowntothe

lowestnoteyouneverheard.Peakingmeans

thatcertainfrequenciesforma“hill”around

thecenterfrequency.)

ThelowEQ

providesupto15dB

boost or cut below

80Hz.Thecircuitis

at(noboost

orcut)atthecenter

detentposition.Thisfrequency

representsthepunchinbassdrums,bass

guitar,fatsynthpatches,andsomereally

seriousmalesingerswhoeatbrokenglassfor

breakfast.

Usedinconjunctionwiththelowcut[34]

switch,youcanboostthelowEQwithout

injectingatonofsubsonicdebrisintothe

mix.Werecommendusingthelowcutfeature

onallchannels,exceptlowfrequencysignals,

likekickdrumsandbassguitars.

ThemidEQ,or“midrange,”hasaxedbandwidthof

1octave.Themidknobsetstheamountofboostorcut,

upto15dB,andiseffectivelybypassedatthecenter

detent.Thefrequencyknobsetsthecenterfrequency,

and you can create drastic changes with these two

knobs.ManyengineersusemidEQtocutmidrange

33. 4-Band Fixed-Frequency EQ

Thestereochannels(9-16)havea4-band,

xed-frequencyequalization:lowshelvingat80Hz,

lowmidpeakingat400Hz,himidpeakingat2.5kHz,
