21. Power LED
You’ve probably already
guredthisout,butifthe
power[20]switchison,this
LED(light-emittingdiode),
locatedintheoutputsection,
willlight.Iftheswitchisoff,
well,yougettheidea.Ifthe
power switch is on and the
LEDdoesnotglow,oneof
threethingshashappened:
Somebodytrippedoverthe
power cord and yanked
itfromtheoutlet,your
electricity has been turned
offduetononpayment,or
thefusehasblown.
22. Phantom Switch
Thisswitchcontrolsthephantompowersupply
forallthemicinputs,asdiscussedonpage8.
Whenturnedon(oroff),thephantompowercircuitry
takesafewmomentsforvoltagetorampup(ordown).
Thisisperfectlynormal.Makesurethatyoupulldown
themasterfader,andheadphone/controlroomvolume
beforeengagingthephantomswitch.
23. 48V LED
Thisisjusttoletyouknowwhichwayyouhavethe
phantom[22]switchset.Ifyourdynamicmicswork
andyourcondensersdon’t,chancesarethisLEDisoff,
soturnthephantomswitchon.
You’llnoticethatwhenyouturnthephantom
poweroff,theLEDstaysonforawhile.Thisis
anaturalphenomenon—theLEDisactuallya
voltmetertellingyouthatthephantompowertakes
timetorampitselfdowntozerovolts.So,ifyou’ve
turnedphantompowerofftoconnectsomethingto
themicinputs,waituntiltheLEDstopsglowingand
thenmakeyourconnectionssafely.
