Model 24 Access Station
The Model 24 Access Station allows broad-
cast personnel to access the four IFB chan-
nels associated with two Model 2A units.
The Model 24 contains five lighted pushbut-
ton switches, four of which are used to ac-
tivate and display the status of the four IFB
channels and one that provides an “all call”
function. The Studio Technologies’ Model
11A Gooseneck Microphone or a line-level
audio source can be connected. Up to four
Model 24 units can be connected and sup-
ported by two Model 2A units. The Model
27A 19-Inch Rack Adapter allows a Model
24 and a Model 11A Gooseneck Micro-
phone to be mounted in a single space of
a 19-inch rack enclosure. The Models 11A,
24, and 27A are purchased separately.
Model 32A and Model 33A Talent
Amplifiers
The Model 32A and Model 33A Talent
Amplifiers are self-contained “beltpack”
units that support connection of talent ear-
pieces or headsets. Purchased separately,
a total of up to six of these talent amplifiers
can be connected to, and powered by, a
single Model 2A Central Controller.
The Model 32A is intended for use by on-air
and production support personnel. It con-
nects to the Model 2A’s talent amplifier
output by way of a standard audio cable
that uses 3-pin XLR connectors. A “loop
through” 3-pin XLR connector is provided
on the Model 32A for easy interconnection
with additional talent amplifier units. The
Model 32A contains a power active LED
indicator light and 2-position source switch,
along with an output level control. For user
convenience, both ¼-inch and 3.5 mm mon-
aural output jacks are provided. Either IFB
channel 1 or 2 can be selected, amplified,
and sent to the output jacks with the level
adjusted as desired.
The Model 33A is similar to the Model 32A
but allows creation of a “mix” of IFB chan-
nels 1 and 2. Two level controls, along with
a source select switch, allows camera and
production personnel to hear cues from
either or both IFB channels. This allows
IFB signals intended for support person-
nel and on-air talent to be simultaneously
monitored. For user convenience, ¼-inch
and 3.5 mm monaural output jacks are
provided.
Model 2A Central Controller
Mounted in a single space of a 19-inch
rack, the Model 2A provides everything
required to implement a 2-channel IFB
system. Features include multiple program
inputs, telephone interfaces, voice-oper-
ated (VOX) interrupt, level meters, monitor
amplifier output, and an internal interrupt
microphone. In addition, up to four Model
22 or Model 24 Access Stations can be
connected to a Model 2A, allowing pro-
ducer or director positions to access the
IFB channels. In addition, up to six Model
32A or Model 33A Talent Amplifiers can be
connected to a Model 2A. These portable
“beltpack” units interconnect with a Model
2A using standard microphone cables.
Both DC power and two channels of au-
dio are supplied on just one 3-conductor
cable, providing personnel with convenient,
reliable access to the two IFB channels.
The Model 2A packs numerous features
into a rugged yet lightweight single-rack-
space (1U) enclosure. Standard con-
nectors are used throughout, including
3-pin XLR, ¼-inch 2-conductor, 9-position
D-subminiature, and modular telephone
(RJ11) jacks. A source of 100-240 volts,
