MIC AUDIO FOR THE RECORDER
GETTING MIC AUDIO FOR THE RECORDER CAN BE THE MOST CHALLENGING PART OF
CONNECTING THE RECORDER. MIC AUDIO IS USUALLY NOT AVAILABLE ON AN ACCESSO-
RY CONNECTOR SO THERE ARE 2 CHOICES FOR MAKING THE CONNECTION.
1_ INTERNAL CONNECTION - CONNECTING TO THE MIC AUDIO PIN ON THE BACK OF THE
MIC CONNECTOR INSIDE THE RADIO. (INTERCONNECTING CABLES WITH INLINE CON-
NECTORS ARE AVAILABLE SO THE CONTROL HEAD OF THE RADIO CAN BE REMOVED IF
NEEDED FOR SERVICE.)
2_ MIC INTERCONNECT ADAPTOR - AN ADAPTOR IS AVAILABLE FOR RADIOS THAT USE
RJ45 MICROPHONES. THE ADAPTOR CAN MOUNT CLOSE TO THE RADIO OR ON THE RADIO
MOUNTING BRACKET. THE MIC PLUGS INTO THE ADAPTOR AND THE ADAPTOR PLUGS IN-
TO THE RADIO. CONNECTIONS FOR THE MIC AUDIO AND THE PTT CAN BE MADE INSIDE
THE ADAPTOR.
CONSIDERATIONS:
_ SOME MICROPHONES DO NOT GATE THE AUDIO WITH THE PTT . IF THE MIC AUDIO FROM
THIS MIC IS CONNECTED TO THE RECORDER, ALL OF THE AUDIO NEAR THE MIC WILL BE
RECORDED. _ ( YOU DON ’ T WANT THIS! )
_ THE RECORDER CAN GATE THE MIC AUDIO WITH A PTT INPUT GOING LOW . (MUST BE
PROGRAMMED ON THE CONFIGURATION SCREEN)
_ A PTT INPUT ON THE ACC CONNECTOR WILL NOT NECESSARILY GO LOW WITH A RADIO
MIC PTT. TO GATE THE MIC AUDIO, YOU MUST GET THE PTT FROM THE RADIO MIC.
_ THE MIC INTERFACE ADAPTOR WILL ALLOW YOU TO GET MIC AUDIO AND MIC PTT FROM
THE RADIO MIC . (FOR RJ45 CONNECTORS)
_ IF MIC AUDIO GATING IS NEEDED AND THE ADVISOR ENCODER/DECODER IS USED , THE
PTT AND MIC AUDIO MUST BE TAKEN FROM THE RADIO MIC. CUT THE JUMPER IN THE
ADAPTOR SO THE MIC AUDIO GOES TO THE ADVISOR, THROUGH RELAY CONTACTS AND
BACK TO THE RADIO. THE ADVISOR TX AUDIO IS THEN FED TO THE MIC CONNECTOR OF
THE RADIO. THE “ DE EMPHASIS ” OPTION SHOULD PROBABLY BE SET.
