TELCO/CODEC MODULE QUICK GUIDE
Up to four Telco modules may be installed into any input module position in the
mainframe. The module has a single input (analog or digital). DIP switches set the
input source and other module functions, such as the Telco ID number for the mod-
ule. A logic connector allows control of the connected device. Telco modules can be
assigned to any of the four program, Send, Off-Line, Telco Record, and Telco Monitor
buses. Text on using the Telco module’s special functions follows on pages 3-7 to 3-9.
PROGRAM BUSES
This section allows the four main outputs and one off-line output to be selected.
It also sets manual or automatic foldback.
PGM 1 - 4 — Assigns the module to any combination of the Program 1,
Program 2, Program 3, and Program 4 buses. When the module is
assigned to a bus, the associated button is lit. A “winking” button indicates
the bus output being used as the Foldback Mix.
OFFLINE (O/L) — The off-line bus is used for building up off-air mix-
minuses. The Telco module feed to this bus is always pre-switch but post-
fader. When assigned to this bus, the O/L button lights. A “winking” button
indicates the output that’s being used as the Foldback Mix.
AU TO — When lit, automatically switches the foldback mix between a
program bus (when the module is on) and the off-line bus (when the
module is off). When unlit, the foldback mix is not affected by the module
on/off status. For more information on the Foldback Mix and using the
Auto button, see pages 3-7 to 3-9.
