• EQ1(willalsobringSC-1outofStandbyifneeded)
• EQ2(willalsobringSC-1outofStandbyifneeded)
• EQ3(willalsobringSC-1outofStandbyifneeded)
• EQOFF(willalsobringSC-1outofStandbyifneeded)
• STATUS(willprovidealistingofcurrentstatustothecontrol
system)
CommandsareterminatedbyeitheraCR(carriagereturn)orLF(linefeed)
character.Communicationparametersare9600,N,8,1.Responsesto
allcommandsareeitherOKorERROR(aswhentryingtoaddressanon-
existentsetupmemory).
Ifanyoftheinputsareclippedduetoexcessiveincomingsignalvoltage,
theRS-232willsendamessageindicatingwhichADChasexperienced
clipping.Itwillalsosendamessagewhenclippinghasstopped.
ThecalibrationroutinesarenotsupportedviatheRS-232port.Yourin-
stallerwillneedtousetheUSBportforthecalibrationprocess.
7 12v Trigger In and Out
These12vtriggerjacksprovidecompatibilitywithawiderangeofprod-
uctstofacilitateremoteturn-onandturn-offinsystems.These
1
⁄8"(3.5
mm)“mini-jacks”allowothercomponentstobringtheSC-1inandoutof
standby.Twosuchmini-jacksareprovidedtoallow“daisy-chaining”of
thisturn-onsignalwithothercomponents,suchasampliers.
Theremotetriggerinputwillbeoperatedbyanypositive-polarityDC
signalbetween3–20volts(onlyafewmilliampsarerequired),withtippo-
larityasshownbelow:
Remote turn-on
tip polarity
+–
Input Signal: 3-20 volts @ less than 10 mA
Output Signal: 12 volts @ 100 mA
TheDCTriggerInputhaspriorityoverthefrontpanelswitch.Therefore,if
atriggervoltageispresentatthisinputconnector,theunitwillbeforced
onandthefrontpanelswitchwillbeignored.Whenthevoltagetransi-
tionsfromhightolow(off),theunitwillgointostandby.
Whenthereisnovoltagepresentatthetriggerinput(eitherbecausethe
controllingdeviceisnotsending,orbecausetheplugisremoved),the
frontpanelswitchwilloperatetheSC-1asyouwouldexpect.
The12vTriggerOutputjackisdriventoa“high”stateof12voltsafew
secondsaftertheSC-1isturnedon,andcansourceasmuchas100mAof
currentat12volts.Thissignalmaybeusedinturntocontrolothercom-
ponents,suchastheWisdomAudioSA-seriesofampliers.EachWisdom
AudiocomponenthasashortdelaybuiltintoitsDCtriggersystemtofa-
cilitateastaggeredturn-onsequence.
YourWisdomAudiodealercanhelpyoutakeadvantageofthesedesign
featurestomaximizeyoursystem’sconvenienceandversatility.
