1 General Information
Each Telco module includes the following con-
trols or features: channel on/off control, fader level
control, cue control, mode selection with pan/bal-
ance control, Send control, record and monitor
controls, and output/Foldback selection to four
program buses and one off-line bus. Logic I/O is
available for logic wiring to/from the hybrid or
codec.
Remote Line Selector (RLS) Module
This module (PRE99-1323) features two banks
of eight selection buttons to independently route
the eight input signals to the two outputs. The
module switch either analog or digital signals, as
set by a DIP switch on the module.
Meter Switcher Module
This module (PRE99-1317) is located to the
right of the input module area. It provides control
of the digital timer and contains the meter source
selector buttons and the signal drivers for all the
meter displays.
The timer control section features stop, start,
hold, and reset controls, as well as whether the
modules automatically reset the timer.
Control Room Module
This module (PRE99-1318) contains the moni-
tor source selection and control facilities for the
console operator, and a co-host and a guest in the
control room. The module has parallel logic con-
trol (via a 14-pin connector) which provides ex-
ternal monitor dimming or muting, and warning
light control. The module includes four external
monitor inputs and six monitor and headphone
outputs. The outputs can simultaneously monitor
any combination of up to six analog sources (four
external inputs and Telco Record and Monitor)
and two digital sources (four programs and Send).
The Control Room module features monitor and
headphone fader-level controls, monitor-mode con-
Universal Analog/Digital Input Module
The Universal Input modules (PRE99-1315)
feature two inputs (A and B), each of which can
accept analog or digital signals. Setup switches on
the module set the source for each input. They
also set the source level (for analog signals) or the
attenuation amount (for digital signals). Each in-
put has its own fully independent parallel logic
control connector for remote control of the mod-
ule and/or module control of the associated source
equipment.
Each Universal Input module includes the fol-
lowing controls or features: A/B input selection,
channel on/off control, fader level control, cue
control, mode selection with pan/balance control,
Send control, and output bus selection to four pro-
gram buses and one off-line bus.
Two 24-pin logic connectors connect logic wir-
ing to/from external control panels or peripher-
als. DIP switches set logic and module function
options for the A and B inputs.
Telco/Codec Input Module
Up to four Telco/Codec (Telco) modules can be
installed into any of the input module slots on the
mainframe. The optional Telco module (PRE99-
1316) has a single audio input (analog or digital)
from a remote send and receive device (like a tele-
phone hybrid, satellite transceiver, ISDN interface,
or other stereo or mono Codec).
Each module features manual or automatic con-
trol of the Foldback signal returned to the hybrid
or codec. The Foldback signal for each Telco mod-
ule can be manually set to any program or off-line
bus. The Foldback signal can also follow the Telco
module’s on/off status when the Auto-Foldback
function is active. The Auto-Foldback function
automatically switches the feed to the caller be-
tween the off-line mix and the assigned bus with
the highest priority. For more information, see the
Telco Operation section on pages 3-7 to 3-9.
