IFB FUNCTION

With the IFB Mode switches #36 on the rear panel, channel E respectively channel F can be put into IFB
Mode, which is indicated on the front panel by lit IFB Mode LED indicators. The channel is now a so-called
IFB channel, used for one way communication from i.e. a director/producer to a talent in a broadcast
environment: If the director pushes the TALK button of an IFB channel, the talent hears the producer but
may also listen to an auxiliary signal. The talent has a headphone or an earpiece, connected to a PS-10
analog IFB receiver (1 channel / listen only) or a standard 1-channel ASL analog beltpack.
IFB channel Properties:
•
The TALK button of an IFB channel is
momentary only and must be kept pushed
while talking.
•
Whilst the TALK button of an IFB channel
is kept pushed the level of the AUX signal
to that channel is dimmed automatically.
This is the so-called IFB Dim Factor
which can be adjusted (0% to 100%) by
turning knobs #23 for each IFB channel
separately .
•
For as long as the TALK button of an IFB
channel is kept pushed, the TALK buttons
of the intercom channels are switched off
automatically. To achieve that one can talk
to an IFB channel and to all intercom
channels of which the TALK buttons are
enabled (the corresponding Talk LEDs
were lit), the position of a certain DIP
switch has to be changed. See section
11.0, DIP switch A
WARNING: A channel from another intercom system should via its system link connector
not be linked to a channel which is in IFB mode.

For as long as the TALK button of an IFB
channel is kept pushed, the Listen
functions of the intercom channels are
disabled automatically (one does not hear

channels). To achieve that these Listen
functions are not disabled if an IFB TALK
button is pushed, the position of a certain
DIP switch has to be changed. See

are automatically disabled. Pushing the
ALL MIC MUTE button or the ALL
