3.9 MONAURAL OUTPUT/TELCO MIX MODULE
This optional module includes the independent functions for the Mono Main and Aux Outputs and the
Telco Inputs, Outputs and Monitor. The Telco Mix half of the module produces the two outputs fed back
to the callers. Each of the caller Feeds is a mix-minus output consisting of the selected SEND TO
TELCO bus (normally the UTL bus, as described below) plus any selected callers minus the caller
himself. This mix-minus matrix is best illustrated through the module's block diagram in Section 7.1.7.
NOTE: To assign a caller to an output bus (such as the PGM bus for "on-air" Telco operations), select
the desired bus on the caller's Input module and turn the module ON. Do not assign the caller's Input
module to the SEND TO TELCO bus (normally UTL), as the callers are added to the base mix-minus
using the TELCO INPUT assignment buttons, as described below.

UTILITY BASE MIX
The Utility (UTL) bus is normally assigned as the base mix bus for Telco operations by configuring the
console as follows:
1.
Assign all Input modules to be included in the base mix to the UTL bus. Do Not assign any
Input Module with the Telco input to the UTL bus.
2.
Select only UTL on the SEND TO TELCO switches.
3.
Select which callers to add to the base mix using the TELCO-1 and TELCO-2 INPUT
assignment buttons.

NOTE: The Monaural Output and Telco Mix sections of this module function
independently. The Monaural Output operations are covered in Section 3.8.
•
The three SEND TO TELCO assignment switches selects the console buses
that are fed to all telephone callers (normally the Utility bus, as described
below).
•
The TELCO-1 and TELCO-2 INPUT buttons select the input feeds from the
Input Modules assigned as telephone hybrid inputs and assign them to the
mix matrix, where the two Telco outputs and the monitor mix are created.
•
MONITOR controls the level of the variable Telco Monitor Output.
NOTE: Both Telco Monitor Outputs (fixed and variable) are non-muted
caller-only outputs.
