Studio Control Module
(SCD-5)
Module Overview
The SCD-5 module is similar to the CRD-5 control room module,
only it controls monitor audio and talkback to two additional (“non-
control room”) studios. The monitor signal being sent to these two
studios follows the source select switching at the top of the module; this
switching is identical to the control room module’s, and includes the
console’s three stereo outputs (PGM, AUD, & UTL), as well as two
external stereo line level inputs brought directly into the module.
Each studio has its own level control and talkback switch. While a
talkback switch is pressed and held (the switches are momentary
action) the console operator’s microphone signal will interrupt the
regular monitor signals being sent to the studio in question. The
TALKBACK master level control in the center of the module sets the
level of this talkback interrupt signal.
All user wiring to and from the SCD-5 module takes place at
12-pin AMP connectors mounted directly beneath the module on the
console mainframe’s bottom pan. There are four connectors: A and B
(towards the console meterbridge) handle external talkback out and
regular studio monitor outputs, plus the console’s Tally 2 and Tally 3
control signals; C and D connectors (near the console armrest) accept
the module’s two external source inputs, and output two additional pre-
level control studio outputs.All audio connections are (+4dBu bal-
anced) analog signals.
