TALK
The TALK switch enables the presenter or operator to communicate with the tele-
phone caller with the presenters channel fader down so the presenters 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-10, the factory default is mono channel 1. The signal source is pre-
fade and pre-mute on the selected mono channel.
CLF SCE
The Clean-Feed Source switch selects the signal source for the TELCO output. 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 the 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 the 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 inter-
view with a telephone caller (or callers), using pre-fade signals to the AUX bus for
later playback or editing for the broadcast.
AUX
This control sends a signal to the auxiliary bus. The signal is sourced pre-fade (and
pre ON switch) or post-fade (and post ON switch) depending on the PRE switch
position. The send control varies the signal level to the bus from off (fully attenu-
ated) to +6dB, with unity gain at the arrow.
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. 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.
