STUDIO CONTROL MODULE
Studio Control Module
(SCD-70)
Module Overview
The SCD-70 module is similar to the CRD-70 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, AUX1 & AUX2) as well as the same two external
stereo line level inputs that feed the CR monitor.
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 (see page 2-3) will interrupt the regular monitor
signals being sent to the studio. The TALKBACK master level control
sets the level of this talkback interrupt signal.
Each D-70 console has two pairs of left-right digital LED meters:
PGM and SWT (switched) located on the console’s meterbridge. The
switched meter follows the SELECT switching, allowing the console
operator to meter AUD, AUX1, AUX2 and external stereo line signal.
When EXT is selected, the switched meter will display the level of the
signal that is input to a digital or analog line input panel installed in
input panel slot 13 (20 position frame) or slot 21 (28 position frame).
See the rear panel layout on page 1-5.
All user wiring to and from the SCD-70 module takes place at
six-conductor connectors mounted on the module’s rear panels. The
two rear panels, MONITOR 1 and MONITOR 2, are shared by the
CRD-70 and SCD-70 modules. All audio connections are (+4dBu
balanced) analog signals.
