Introduction
The IFB Plus Series Model 2A Central
Controller from Studio Technologies is a
highly integrated, 2-channel IFB (interrupt-
ible foldback) unit. It is the main component
of the IFB Plus Series which is expressly
designed to provide talent cueing for ENG,
SNG, OB, and mobile production facilities.
It can also find use in fixed installations
that need a compact but feature-rich stand-
alone IFB system. The performance and
features of the Model 2A, along with its
companion accessories, reflect the needs
of contemporary applications. Only after
extensive polling of field production and
engineering personnel was the Model 2A’s
feature group established. We think you’ll
find it to be a great addition to your facility.
What This User Guide Covers
This guide is designed to assist you when
installing, configuring, and using the Model
2A Central Controller and related accesso-
ries. The following items will be covered in
this User Guide:
Model 2A Central Controller
The Model 2A Central Controller is an in-
tegrated 2-channel IFB unit intended for ap-
plications where space is at a premium, yet
high performance is still required. The unit
contains everything required to implement
a full-featured system in a single space
(1U) of a 19-inch rack enclosure. The unit’s
resources include multiple program inputs,
integral telephone interfaces, monitor ampli-
fier output, internal interrupt microphone,
and support for additional talk locations.
The unit’s power input can range from 100
to 240 volts, 50/60 hertz. This “universal
input” ensures correct operation virtually
anywhere in the world.
Model 22 Access Station
The Model 22 Access Station is used by a
producer or director to access the Model
2A’s two IFB channels. It allows connec-
tion of a Studio Technologies’ Model 11A
Gooseneck Microphone or a line-level audio
source. The unit contains two lighted push-
button switches which display IFB interrupt
status. Up to four Model 22 units can be
connected to and powered by a Model 2A
Central Controller. The Model 25A 19-Inch
Rack Adapter allows a Model 22 Access
Station and Model 11A Gooseneck Micro-
phone to be mounted in a single space
(1U) of a standard 19-inch rack. 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. The Models 11A,
22, 25A, and 28A are purchased separately.
