STUDIO CONTROL MODULE
Hook-Ups
As stated before, all user wiring to and from the SCD-5 module takes
place at four AMP type 12-pin connectors mounted directly beneath the
module on the console mainframe’s bottom pan.
AMP A, B Connectors — Audio
Includes studio 1, studio 2 and (mono) talkback outputs. All audio
signals are analog, +4dBu balanced.
Pin 1 – TB Out SH
Pin 3 – TB Out HI
Pin 2 – TB Out LO
Pin 7 – Lt Studio 2 Out SH
Pin 9 – Lt Studio 2 Out HI AMP A connector
Pin 8 – Lt Studio 2 Out LO
Pin 10 – Rt Studio 2 Out SH
Pin 12 – Rt Studio 2 Out HI
Pin 11 – Rt Studio 2 Out LO
Pin 1 – Lt Studio 1 Out SH
Pin 3 – Lt Studio 1 Out HI
Pin 2 – Lt Studio 1 Out LO AMP B connector
Pin 4 – Rt Studio 1 Out SH
Pin 6 – Rt Studio 1 Out HI
Pin 5 – Rt Studio 1 Out LO
AMP B Connector — Control
The console’s Tally 2 and Tally 3 control ports are on the SCD-5
AMP B connector. These are simple relay closures that activate whenever
programmed input modules are turned ON (see page 2-4). The ports can
be used to control externally powered tally lights that requires a continuous
closure to function.
Pin 11 – Tally 2 Relay COM
Pin 12 – Tally 2 Relay N.O.
Pin 8 – Tally 3 Relay COM
Pin 9 – Tally 3 Relay N.O.
Maximum current through
the tally relay closures is
2 amps @30VDC.
