Control Room/Studio
Module
(CRS-2600)
Module Overview
The CRS-2600 module is the 2600 console operator’s monitor module.
It allows the operator to listen to the console’s two stereo (PGM & AUD)
outputs, two mono (MONO & PRE) outputs, and an external stereo line
level input brought directly into the module.
A recessed front panel multi-turn trimpot adjusts talkback level.
The CRS-2600 module also houses three console monitor circuits,
which follow the source selection switches. They are:
CONTROL ROOM (CR)—a dedicated output designed to drive a
separate, user provided power amp/speaker system in the main control
room;
STUDIO—a second stereo output intended for a remote (i.e., non CR)
studio power amp/speaker system;
HEADPHONE (HDPN)—an additional output (w/built-in power amp)
that drives the console operator’s headphones. There are two types of
headphone output: the -2dBu unbalanced output at the module’s DB-25
connector, and the headphone jack mounted in the right-hand corner of the
console, which is actually the output from a built-in headphone amplifier.
The CRS-2600 module has a talkback switch. When the talkback
switch is pressed (it is momentary action) the console operator’s micro-
phone signal will interrupt the regular monitor signals being sent to the
studio.
All user wiring to and from the CRS-2600 module takes place at the
DB-25 multi-pin connector mounted at the top of the module and located
underneath the hinged meterbridge. All audio connections are stereo line
level analog signals. A pinout drawing on page 5-5 shows all wiring
connections at a glance.
