Model IFB Plus Series Talent Amplifier User Guide

Model 2A User Guide Issue 2, March 2015
Studio Technologies, Inc. Page 5
Introduction
The IFB Plus Series Model 2A Central Con-
troller from Studio Technologies is a highly
integrated, 2-channel IFB (interruptible fold-
back) 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 contem-
porary 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 inte
-
grated 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

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

console, etc. The Models 11A, 22, 25A, and
