I
nterrupt Fold Back (IFB) is a broadcast term used
to describe the process of cueing on-air talent.
RTS IFB equipment is designed with a modular
approach that meets the needs of not only large
television networks, but also can be configured
for any one-way communications need. With
multiple program audio sources and individual or
simultaneous interrupts, the RTS series of IFB and
ISO products is perfect for any talent-cueing need.
The
4010 is a central IFB electronics station.
It contains all necessary control functions and
electronics, including line power, to provide an active
link between the 4001, 4002, and 4003 control
stations and the 4030 and IFB-325 user stations.
The
IFB-828 interfaces up to eight RTS IFB-
325 or 4030 IFB beltpacks to any RTS Digital
Matrix Intercom system, and provides power to
the beltpacks. The IFB-828 may also be used as
a simple program interface to feed two separate
program sources to each of eight 4030 beltpacks
(16 program sources to eight beltpacks total).
The
4030 and IFB-325 are listen-only IFB earset
stations with two and one channels, respectively.
The 4030 contains electronics to provide a stereo
audio signal to the user. The IFB-325 provides
a mono (either interrupt non-interrupt selected
at 4010) audio signal to the user. The 4030 and
IFB-325 feature volume controls in extruded
aluminum cases. For earset options see page 38.
The
4001, 4002, and 4003 are IFB Control
stations with four, eight, and 12 channels, respectively
thus the control stations separate talent feeds per
channel plus one stage announce send. The control
stations feature two distinct audio sends per IFB
channel for interrupt/non-interrupt or multiple
program feeds. Each unit has illuminated switches,
programmable priority levels and gooseneck mic
connector and is shipped with a wall power supply.
Optional rack kit is also available. Requires one
4010 Central IFB. 4001 and 4002 not displayed.
