21. 48V Phantom Power
Mostmodernprofessionalcondensermicsrequire
48Vphantompower,whichletsthemixersend
low-currentDCvoltagetothemic’selectronicsthrough
thesamewiresthatcarryaudio.(Semi-procondenser
micsoftenhavebatteriestoaccomplishthesame
thing.)“Phantom”owesitsnametoanabilitytobe
“unseen”bydynamicmics(ShureSM57/SM58,for
instance),whichdon’tneedexternalpowerandaren’t
affected by it anyway.
Pressthetopofthisswitchinifyourmicrophone
requiresphantompower.(Alwayschecktheposition
ofthisswitchbeforeconnectingmicrophones.)Ared
LED[56]willilluminatejustabovethemainmix
meters[58]toindicatethatphantompowerisactive.
Thisisaglobalswitchthataffectsallmicchannels'XLR
jacksatonce.
Neverplugsingle-ended(unbalanced)

is safe to do so. Besurethemainlevel[75]isturned

22. Power Connection
Thisisastandard3-prongIECpowerconnector.
Connectthedetachablelinecord(includedinthebox
withyourmixer)tothepowerreceptacle,andplugthe
otherendofthelinecordintoanACoutlet.The
VLZ44•BusSeriesMixershaveauniversalpower 
supplythatcanaccept
any AC voltage ranging from
100 VAC to 240 VAC. No need for voltage select switches.
Itwillworkvirtuallyanywhereintheworld.That’swhy
wecallita“Planet-Earth”powersupply!Itisless
susceptibletovoltagesagsorspikes,comparedto
conventionalpowersupplies,andprovidesgreater
electromagneticisolationandbetterprotectionagainst
AC line noise.
Disconnectingtheplug’sgroundpinis
dangerous.Don’tdoit.
