Introduction
The IFB Plus Series Model 2 Central Con-
troller from Studio Technologies is a highly
integrated, 2-channel IFB (interrupted
foldback or interrupted feedback) system
contained in a single rack space unit. It is
expressly designed to provide talent cue-
ing for ENG, SNG, and mobile production
facilities. The performance and features of
the Model 2 reflect the needs of contem-
porary applications. Only after extensive
polling of field production and engineering
personnel was the Model 2’s feature group
established. We think you’ll find the Model 2
a great addition to your facility.

Schematic diagrams are available upon
request.
The following items will be covered in this
User Guide:
Model 2 Central Controller
An integrated 2-channel IFB unit intended
for applications where space is at a pre-
mium, yet high performance is still required.
The unit contains everything required to
implement a full-featured system in a single
rack space. Includes multiple program
inputs, integral telephone interfaces, moni-
tor amplifier, internal interrupt microphone,
among many other features. The unit is
powered by 120 or 220/240 V, 50/60 Hz.
Model 22 Access Station
Used by a producer or director to access
the Model 2’s IFB channels. Allows connec-
tion of a Studio Technologies Model 11A
gooseneck microphone or a line-level audio
source. Contains two lighted pushbutton
switches which display IFB interrupt status.
Up to four Model 22s can be connected to
and powered by a Model 2 Central Control-
ler. The Model 25A 19-inch Rack Adapter
allows a Model 22 Access Station and
Model 11A gooseneck microphone to be
mounted in a single 19-inch rack space. The
Model 28A Panel Adapter allows a Model 22
and Model 11A gooseneck microphone to
be installed in an opening made in a table,
equipment console, etc.
Model 32 & Model 33 Talent Amplifiers
The Model 32 and Model 33 Talent Ampli-
fiers are self-contained “belt pack” units that
drive talent ear pieces or headsets. Up to
four Model 32 and/or Model 33 Talent Ampli-
fiers can be connected to, and powered by,
a single Model 2 Central Controller.
The Model 32 is intended for use by on-air
personnel, and contains a source switch,
along with an output level control. Either
IFB channel 1 or IFB channel 2 can be sent
to the talent, along with the desired audio
“volume.”
The Model 33 is unique in that a “mix” of IFB
channels 1 and 2 can be created. Two level
controls, along with a source select switch,
allows camera and production personnel to
hear IFB cues from either or both channels.
This allows IFB signals intended for both
technician and talent to be simultaneously
monitored.
