Introduction


TheDA12isadualchanneldistributionamplifierforSMPTE,EBU,
IRIGandothertimecodes(TC).InputsareprovidedthroughBNC
connections.Theunitprovidesinputsforsingle‐ended,balanced
andunbalancedtimecode.


Installation

SimplyinstalltheDA12intoyourrackmountsetup.Theunituses
ACpower.ConnectyourinputsandoutputsusingBNCcables.



InitialOperation

Setupforinitialoperationconsistsof:
•Supplyingasourceoftimecode
•Connectingapowersource
•Adjustingthegainofindividualchannels
•Configuringtheoutputswitches(locatedonback)
•Connectingtooneormoretimecodereaderdevices

SUPPLYINGATIMECODESOURCE
Asourceoftimecodeisrequired.Thismaybeintheformof
electronicpulse,radiofrequency,DCIRIGTimeCodeorAMIRIG
TimeCode(TC).TCisanaudiosignalsimilartothatofamodem.It
canberoutedoverunshieldedwire,likeflattelephonecable,or
overaRG‐58/59coaxialcable.
ConnecttheTimeCodesourcetotheinputBNCconnectororthe
appropriatepinsontherearoftheDA12.Theinputhasan
impedanceof50to600ohms.

CONNECTINGAPOWERSOURCE
ApplypowerbyinsertingtheACcordintoanappropriateAC
powersource.TheinputrangeoftheDA12is0to25Vp‐pfor
SMPTEandIRIGTC.

ADJUSTINGTHEGAINOFINDIVIDUALCHANNELS
TheoutputrangeoftheDA12isadjustablefrom0to12dBintoa
600ohmload.Eachoutputchannelbankisadjustableviathegain
controlsonthebackoftheunit.
Thetwogainadjustmentsscrews(inblueandinsetontheback
panel)modifythegainoftheirrespectivesetsofoutputs.
Turningthegainadjustmentclockwiseincreasesthegainonthe
appropriatechannel.Turningitcounterclockwisedecreasesthe
gain.Theunitsareshippedforunitygainwith2VP‐PSMPTETC.

CONFIGURINGTHEOUTPUTSWITCHES
TherearethreeswitchesonthebackoftheDA12andtwogain
adjustmentswhichrequireaPhillipsheadscrewdriver.
