TELCO/CODEC MODULE QUICK GUIDE
Up to six Telco/Codec modules may be installed in the console. Most controls are
the same as a Universal Input module (On/Off, Fader, mode selection, and bus selec-
tion), but since the module may be connected to an External RLS or router, or may
come from a VistaMax System, there is a Source Selector and Take button on this
module (taking the place of the A/B selectors). There is also a Talkback button for
talking to the caller or remote in addition to Telco record enable and monitor select
buttons. Additional operational details on special Telco functions are presented on
pages 3-8 to 3-10. A limited-feature version module is also available, which does not
have the Send and Utility bus controls.
SEND & UTILITY BUSES
This section has the selectors for the four Utility outputs and the two Send.
Refer to page 3-4 for their functions.
PROGRAM BUSES
This section has the selectors for the four Program outputs and the two off-
line buses. The AUTO F/B button sets up how the Foldback (the return feed to
the caller) is selected.

When lit, routes the module to any combination of the Program 1, Program
2, Program 3, and Program 4 buses. The “winking” button indicates the
bus that is being used as the Foldback Mix source (see pages 3-8 and 3-9 for
foldback details). When unlit, the module audio does not feed that bus. These
outputs are always post-switch and post-fader.

When lit, routes the module
audio to any combination of the Off-Line 1 and Off-Line 2 buses (which are
used for building up off-air mix-minuses). A “winking” button indicates the
bus that is being used as the Foldback Mix source (see pages 3-8 and 3-9).
The Telco Off-Line feeds are always pre-switch and pre-fader.

Automatic Foldback. When lit, automatically switches the
Foldback Mix source between the “winking” off-line bus (when the module is
off) and the “winking” program bus (when the module is on). For details on
this function, see pages 3-8 and 3-9.
MODE/PAN/BAL
This section has the controls for setting the module’s mode (stereo or mono)
and the pan or balance of the module’s bus outputs. Refer to page 3-5 for
their functions.
