50. Aux Sends Solo and LED

Onceagain,inlivesoundsituationsauxsend1and

checkthemixyou’resendingthem,andthat’swhat

thesetwobuttonsarefor.(Aux3and4havenosuch

switch.)BesideeachswitchisagreenLEDthat,just

Theonlythingdifferentaboutauxsendssoloisthat

it’snotreallyPFL(pre-faderlisten),andit’snotreally

SIP(solo-in-place),it’sactuallyAFL(after-fader

listen).DuringAFL[44]mode,you’llgetauxsend1’s

sideofthecontrolroomoutputs,phonesoutputand

everuseaux1and2tocreateastereomonitormix,

you’llunderstandwhy.)InPFLmode,you’llgetthe

51. Stereo Returns (Level)

Thesefourcontrolssettheoveralllevelofeffects

receivedfromthestereoreturn[7]inputjacks.These

controlsaredesignedtohandleawiderangeofsignal

levels—eachknobgoesfromoff,tounitygainatthe

detent,to20dBgainfullyclockwise,tocompensatefor

low-leveleffects.Signalspassingthroughtheselevel

controlswillproceeddirectlytothemainmixfader

[37],withexceptionsthatwe’lldiscussinamoment.

Typically,theseknobscanjustliveatthecenter

detent,andtheeffectsdevice’soutputcontrolshould

besetatwhatevertheycallunitygain(checktheir

manual).Ifthatturnsouttobetooloudortooquiet,

adjusttheeffectsdevice’soutputs,notthemixer.

Thatway,themixer’sknobsareeasytorelocate

52. To Aux 1 and To Aux 2

Ifyouwanttoaddreverbordelaytothestage

monitormixes,thesearetheknobsforyou.

Operatingindependentlyoftheirrespectively

knobsareexactlythesameasthechannelstrip

such knobs.

53. Main Mix To Subs (Stereo Return 3)

Withthisswitchup,stereoreturn3behaveslikeall

theothers—itdeliversastereosignal,regulatedby

itslevelknob,tothemainmix.Whenyouengagethis

switch,thesignalsareremovedfromthemainmix

busesandsenttothe1-2/3-4switch,whichdivertsthe

signaloncemore.We’renotnished.Pleasereadon.

54. 1–2/3–4 (Stereo Return 3)

Ifthemainmixtosubs[53]switchisdisengaged,

thisswitchdoesabsolutelynothing.Let’snowassume

it’s engaged. Stereo return 3’s stereo signal will not be

senttothemainmix,buttosu/jointfilesconvert/312633/bgroupfaders1and2

(thisswitchup)orsu/jointfilesconvert/312633/bgroupfaders3and4(thisswitch

down).

Let’ssayyou’vemadeastereodrumsubmixon

su/jointfilesconvert/312633/bgroupfaders1and2,soyoucanridethosetwo

fadersinsteadofthesevenchannelsthatthedrums

hasitsassigntomainmix,rightbuttonengaged,

blendingthedrumsubmixbackintothemainmix.

Thedrumchannelsarealsosendingsignalstoyour

reverbviatheauxsends[6],andthereverboutputs

arepatchedintostereoreturn3[7].Sofarsogood.

Even though you could send stereo return 3 directly

tothemainmix(mainmixtosubs[53]switchup),

youdon’twantto.Instead,engagethemainmixtosubs

switchandmakesurethe1–2/3–4switchisup.Nowthe

reverbreturnwillbeblendedintothedrumsubmix,and

asyouridethosetwofaders,thereverblevelwillfollow.

Whydowewantthat?Becauseifyouhadjustsent

why we threw in these switches.
