trol (with the selectable global fader start feature),
Cue and Off-Line control and output selection to
three program buses. Faceplate channel trim con-
trols allow the analog version to accept input lev-
els from -10 dBu to +4 dBu.
The module’s inputs are electronically switched
through a faceplate A/B Input selector. Logic wir-
ing to/from external peripherals connects to a 24-
pin logic connector on the faceplate. Logic and
module function options for the A or the B input
are set through a ten-position faceplate DIP switch.
A second, optional interface connector is available
for separate logic control for the A and B inputs.
Telco Input/Output
Up to two optional Telco modules can be in-
stalled into the mainframe next to the monitor
module. These provide the audio and logic con-
nections for up to two telephone hybrids and two-
channel recorders. A faceplate trim control allows
the module to work with hybrid outputs from -10
dBu up to +4 dBu.
Each Telco module’s output (Feed to Caller) can
be set manually to any one or a combination of
the three program buses and the Off-Line mix
bus. The Autofeed function automatically
switches the Feed to Caller between the Off-Line
mix and the assigned bus with the highest prior-
ity when the Telco module is turned off and on
(for more information, see the Telco Operation
section) .
Monitor
A double-width module with the monitoring and
communication controls for a control room (C/R)
and separate studio or voice booth. Volume
controls for C/R and studio speaker volume, C/R
headphone and Cue are included with independent
source selection for each room (three external
inputs, Pgm-1, Pgm-2, Pgm-3 and Telco). The
module includes a C/R to studio talkback system
with built-in adjustable electret talkback mic. Both
C/R and studio warning outputs are provided.
Output
Contains the various analog stereo line output
amplifiers and the AES-3 digital outputs for the
Program-1 (Pgm-1), Program-2 (Pgm-2) and Pro-
gram-3 (Pgm-3) buses. A monaural analog out-
put of the Pgm-1, Pgm-2 or Pgm-3 bus (operator-
selected) is also provided. Each balanced analog
output uses a nominal level of +4 dBu. Each digi-
tal output is AES-3 compatible.
This module also has faceplate buttons for the
right-hand signal level meter selection, Program-
2 or Program-3, with momentary Cue bus level
metering. The module also has two DIP switches
for selecting if Fader Start is enabled and the me-
tering scale (VU or PPM).
Timer Control
Provides manual or automatic control over the
digital timer located in the meter panel. This
module also routes power to the clock/timer
assembly and provides an external reset for a
studio mounted timer. It also provides for a AA
battery backup voltage to hold the console’s logic
settings in case of momentary power outage.
Remote Line Selector (RLS)
Two line selectors are available: an analog RLS
and a digital RLS. Each is a 7x2 input selector.
The analog version uses balanced, line-level mono
or stereo signals. The digital version uses AES-3-
compatible digital signals. Two banks of seven
switches provide manual, exclusive source
selection, among the seven common external input
signals for the two outputs.
Power Supply
The separately packaged rack mount power
supply is fully regulated and protected by inter-
