Studio Control Module
(SCD-220)
Module Overview
The SCD-220 module is similar to the CRD-220 control room
module, only it controls monitor audio and talkback to an additional
(“non-control room”) studio. The monitor signal being sent to this
studio follows the source select switching. This switching is identical
to the control room module’s and includes the console’s four stereo
outputs (PGM, AUD, AUX & UTL) as well as two external stereo line
level inputs brought directly into the module.
The studio has a level control and talkback switch. When the
talkback switch is pressed (it is 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 sets the
level of this talkback interrupt signal.
All user wiring to and from the SCD-220 module takes place at
DB-25 multi-pin connectors mounted at the top of the module and
located underneath the hinged meterbridge. There are two connectors:
the upper one handles external talkback out and regular studio monitor
outputs, plus the console’s Tally 2 and Tally 3 control signals; the lower
connector accepts the module’s two external source inputs. It also
outputs additional pre-level control studio outputs.All audio connec-
tions are (+4dBu balanced) analog signals. A pinout drawing on page
5-5 shows all wiring connections at a glance.
