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 out-
put. In the un-pressed 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 distracting echo of their
voice.
If the switch is pressed, the TELCO output signal is sourced from the AUX
bus, but minus the AUX 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 using the AUX bus,
the sources may be on or off air because the sources for the AUX bus can
be pre or post fader.
In addition, the AUX bus can be used for off-air audition or recording of an
interview with a telephone caller (or callers), using pre-fade signals to the
AUX bus for later playback or editing for the broadcast. By pressing the CLF
SCE switch the caller will hear the audition mix, or the off-air record mix
without their own voice.
MIX B
The MIX B switch routes the channel signal to a stereo bus which is inde-
pendent of the main PGM (program) bus. The signal is post-fade and follows
the PAN control. The MIX B bus can be used for creating mixes for re-
cording 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 bus and the MIX B bus.
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.
