TheOL(overload)LEDwillcomeonwhenthe
channel’sinputsignalistoohigh.Thisshouldbe
avoided,asdistortionwilloccur.IftheOLLEDcomes
onregularly,checkthatthegaincontrol[23]isset
correctlyforyourinputdevice,andthatthechannel
EQisnotsetwithtoomuchboost.TheOLLEDwill
alsoilluminatewhenachannel'smuteswitch[38]is
engaged.
40. SIG LED
ThisLEDalsoindicatesthechannel’ssignallevel
afterthegainandEQcontrols,butjustbeforethe
channel’slevel.Soevenifthelevelisturneddown,you
canseeifasignalispresent.
TheSIG(signal)LEDwillcomeonwhenthe
channel’sinputsignal(atleast-20dBu)ispresent.
Itshouldilluminatenon-stopifsignalabove0dBuis
presentinthatchannel.ThisLEDwillbesolidwhena
channel'ssoloswitch[41]isengaged.
41. Solo
Wheneverachannel'ssoloswitchisengaged,you
willhearonlythesoloedchannel(s)intheheadphones
andmonitoroutputs.Thisgivesyoutheopportunityto
auditionthechannelsbeforetheyareaddedtothemain
mix.InPFLmodeyoucanhearthesolosignal,even
whenthechannel'sfaderisdown.
Soloisalsousedtosetthegainofeachchannel
correctly.Whenachannelissoloed,adjustthe
channelgain[23]untiltheinputsourcereaches
thelevelofthe0dBLEDoftheleftmeter.Select
PFLontheSOLOMODEswitch[60]forgainsetting.
Solosignalsreachingtheheadphonesand
monitoroutputsarenotaffectedbythe
channellevel(unlesstheSOLOMODEswitch
issettoAFL)ormainlevel;therefore,turndownthe
phoneslevel[69]andmonitorlevel[68]rst,assoloed
channelsmaybeloud.
Therudesololight[59]willturnonasareminder
thatwhatyouarelisteningtointheheadphonesand
controlroomisjustthesoloedchannel(s),2-track
return,stereoreturn(s),aux(es),and/orgroup(s).If
thesolosourceisaninputchannel,thatchannel'sSIG
(signal)LED[40]willilluminatewhenthatchannelis
soloed.
42. Assign
Alongsideeachchannelfaderarethreebuttons
referred to as channel assignment switches. Used in
conjunctionwiththechannel'sbalanceknob[37],they
areusedtodeterminethedestinationofthechannel's
signal.
Withthepanknobatthecenterdetent,theleftand
rightsidesreceiveequalsignallevels(mainmixL-R,
group1-2,andgroup3-4).Tofeedonlyonesideorthe
other,turnthepanknobaccordingly.
Ifyouaredoingamixdowntoa2-track,forexample,
simplyengagethemainmixswitchoneachchannel
thatyouwanttohear,andtheywillbesenttothemain
mixbus.Ifyouwanttocreateagroupofcertain
channels, engage either the 1-2 or 3-4 switches instead
ofthemainmix,andtheywillbesenttotheappropriate
groupfaders.Fromthere,thegroupsmaybesentback
tothemainmix(usingthegroupassignswitches[73]
abovethegroupfaders[74]),allowingyoutousethe
groupfadersasamastercontrolforthosechannels.
Ifyouarecreatingnewtracksorbouncingexisting
ones,youwillalsousethe1-2and3-4switches,butnot
themainmixswitch.Hereyoudonotwantthegroups
sentbackintothemainmixbus,butsentout,viathe
groupoutjacks[11],toyourmultitrackinputs.
43. Channel Fader
Thisisthelastcontrolinachannel’ssignalpath,and
itadjuststhelevelofeachchannelontothemainmix.
The“U”markindicatesunitygain,meaningnoincrease
ordecreaseofsignallevel.Allthewayupprovidesan
additional10dB,shouldyouneedtoboostasectionof
asong.Ifyoundthattheoveralllevelistooquietor
tooloudwiththelevelnearunity,checkthatthegain
control [23] is set correctly.
44. FX1 and FX2
Whenengaged,theseswitches,locatedjustbelowthe
stereochannels'gaincontrols[23],indicatethatyou
wanttoreturntheinternalFXprocessorsignaltothe
stereochannel.TheTRSinputsaredisengagedwhen
theswitchisdepressed.
RemembertoturntheFXprocessorlevel
controlstoaux1/2andmainallthewaydown
toavoiddouble-bussingtheFXreturn.

45. USB Switch
TheUSBswitchonthelaststereochannelprovides
stereoplaybackofiTunes

, or a DAW via the USB
connection.Likeanyotherinput,thissignalmayalso
beEQ'd,senttoanauxbus,ormixedinwiththeother
signalsandassignedtosubgroupsormainouts.This
