Overview
The Model 32A Talent Amplifier is a self-contained listen-only "belt
pack" unit intended for use by on-air talent or production
personnel. It's directly compatible with the Studio Technologies
Model 2 Central Controller as
well as other standard IFB or party-line intercom circuits. The
Model 32A is powered by, and receives audio from, the connected IFB
or intercom circuit. A single 3-conductor microphone-type cable
links the Model 2's talent amplifier output with the Model 32A's
input. Each Model 32A contains both a male and a female 3-pin XLR-type
connector, allowing simple "loop through" connection of multiple
units. Up to four talent amplifiers can be connected to, and powered
by, a single Model 2 Central Controller. A source select switch
allows audio from either Model 2 channel 1 or Model 2 channel 2 to
be routed to the monaural output. For flexibility the audio output
is provided on both ¼-inch and 3.5 mm jacks. An LED indicator lights
whenever input power is present, providing setup assistance and user
confidence. The Model 32A is housed in a lightweight, yet rugged,
aluminum housing. A belt clip allows it to be directly attached to
clothing or accessories. An optional mounting adapter is available
to allow the Model 32A to be installed in a permanent location.
The Model 32A's output is intended to be connected to talent
earpieces or headsets. The user is provided with a source select
switch and a rotary level control. The switch is used to select
which of the two audio inputs is routed to the output. In the
switch’s channel 1 position audio associated with XLR pin 2 is sent
to the output. When the switch is set to its channel 2 position
audio associated with XLR pin 3 is selected. By design, the Model
32A's level control cannot be set to fully attenuate ("mute") the
audio output. This helps to minimize the chance that users will
accidentally miss important "cues" from directors or producers.
While audio quality is not normally considered a factor in IFB or
intercom systems, the Model 32A is built to "pro audio" standards.
This helps to ensure that the best possible audio reproduction is
provided.
The Model 32A is an update of the popular Model 32 Talent Amplifier.
The Model 32A includes the addition of a 3.5 mm output jack, along
with updated internal circuitry. In all ways the Model 32A meets or
exceeds the performance of its predecessor.
In addition to working with the Model 2 Central Controller, the
Model 32A is compatible with virtually every standard IFB and
party-line intercom circuit, including those associated with
equipment from RTS®, Clear-Com®, and Studio Technologies. This type
of circuit typically uses a 3-pin XLR-type connector for interfacing
with connected equipment. Electrically, XLR pin 1 serves as common
for DC power and audio; pin 2 provides DC power and, in the case of
a dual-channel circuit, DC power and channel 1 audio; pin 3 provides
channel 2 audio for dual-channel systems, or channel 1 audio in
single-channel systems.
