Overview
The Model 34 Talent Amplifier is a self-contained listen-only
“belt pack” unit that drives talent earpieces or headsets.
The unit is powered by, and receives audio from, single- or
dual-channel broadcast-standard IFB or party-line intercom
circuits. A 3-conductor microphone-type cable links the IFB
or intercom circuit with the Model 34’s input. The unit’s
resources were selected so that a range of single- and
dual-channel applications can be supported. For flexibility
the dual-channel audio output is provided on both ¼-inch
and 3.5 mm jacks. The jacks are 3-conductor and are
compatible with both monaural (2-conductor) and stereo
(3-conductor) plugs. An LED indicator lights whenever
input power is present, providing setup assistance and
user confidence. The Model 34 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 enabling the Model 34 to be
installed in a permanent location.
The Model 34 is intended for use by on-air broadcast
and production support personnel. The unit provides two
user-accessible rotary level controls and an output mode
switch. The switch is used to select how the one or two
audio input sources are routed to the connected earpiece
or headset. In the switch’s stereo position input channel 1
(XLR pin 2) is sent to the left output channel while input
2 (XLR pin 3) is sent to the right output channel. The two
controls allow the left and right output levels to be inde
-
pendently set. When the output mode switch is set to the
mono position, a “mix” of input channels 1 and 2 can be
created. Using the level controls, camera or production
personnel can create a unique cue mix of either or both
audio inputs. This allows independent IFB signals, such as
those intended for use by on-air talent and technicians, to
be simultaneously monitored. By design, the Model 34’s
level controls cannot be set to fully attenuate (“mute”) the
input sources. This helps to ensure that users will never
accidentally miss important “cues” from directors or pro
-
ducers. While audio quality is not normally considered a
factor in IFB or intercom systems, the Model 34 is built to
“pro audio” standards. This helps to ensure that the best
possible audio reproduction is provided.
