TELCO CHANNELS 

TALK 

The TALK switch enables the presenter or operator to communicate with 

the telephone caller with the presenters channel fader down so the pre-
senters voice does not go to the program mix. 

The source for the TALK signal is one of the mono channels, pre-selected 

by links set within the XB-14, the factory default is mono channel 1. The 
signal source is pre-fade and pre-mute on the selected mono channel. 
  

AUX 

This control sends a signal to an auxiliary bus. The signal is sourced pre-fade 

or post-fade depending on the PRE switch position. The pre-fade source 
selection will be affected by the channel ON/OFF switch if active. The send 

control varies the signal level to the bus from off (fully attenuated) to +6dB, 

with unity gain at the arrow. 

CLF SCE 

The Clean-Feed Source switch selects the signal source for the TELCO 

cleanfeed output. With both buttons in the up position the signal will be the 
entire program (PGM) mix (pre main PGM fader) but without the signal 

from the input on that TELCO channel, so the caller does not hear any dis-

tracting echo of their voice.  
If the AUX or AUDITION switch is pressed, the TELCO clean feed signal is 

sourced from the selected bus, but minus the signal sent from that TELCO 

channel. 

 
This is a really useful feature that can enable the operator to send a mix of 

signals from different channels to the telephone caller, the sources may be 

on or off air because the sources for the AUX bus can be pre or post fader 
or the Audition bus can be used. 

In addition, The telephone conversation could be recorded off air using the 

audition or aux buses, and replayed at a later time.

MIX B 

The MIX B switch routes the channel signal to a stereo bus which is inde-

pendent of the main PGM (program) and audition buses. The signal is post-
fade and follows the PAN control. The MIX B bus can be used for creating 

mixes for recording or clean-feed sources for external equipment.

PAN 

The pan control adjusts how the signal from the TELCO input channel is 

shared between the left and right sides of the PGM, audition and MIX B bus-
es.  Set to the mid position, equal amounts of signal are fed to left and right, 

with pan set to L, none is sent to the Right bus.
