source. A second switch allows the Model
24 to mute the monitor output on each of the
Model 2A units whenever an IFB channel
is activated.
Model 24 Access Stations connect to the
associated Model 2A units using two 9-pin
D-subminiature connectors. The nine con-
ductors that link each Model 2A with the
Model 24 support all the audio, signaling,
and power requirements. No external power
source is required. The optional Model 27A
allows a Model 24, along with a Model 11A
Gooseneck Microphone, to be mounted in
one space (1U) of a standard 19-inch rack
enclosure. Refer to Appendix B for details
on these optional accessories.
Model 32A and Model 33A
Talent Amplifiers
Model 32A and Model 33A Talent Amplifiers,
purchased separately, are self-contained
“beltpack” units that drive talent earpieces
or headsets. An audio cable with 3-pin XLR
connectors on its ends links the talent ampli-
fiers with a Model 2A. Each Model 32A and
Model 33A contains both a male and female
3-pin XLR connector, allowing simple “loop
through” connection of multiple units. Up to
six of the talent amplifiers can be connected
to, and powered by, a single Model 2A Cen-
tral Controller. On each talent amplifier the
audio output signal is provided on both a
¼-inch 2-conductor phone jack and a
3.5 mm output jack. An LED on each unit
lights whenever power is present, provid-
ing setup assistance and user confidence.
Identical in size, each is housed in a light-
weight, yet rugged, aluminum housing.
A belt clip allows it to be attached to belts,
clipboards, scabbards, pizza boxes, pro-
duction assistants, etc. An optional mount-
ing adapter kit (Order Code: TAB-01)
is available, allowing a Model 32A or
Model 33A to be installed in a permanent
location.
The Model 32A is typically used by on-air
personnel, and contains a source selection
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.”
