Model 34
Talent Amplifier
Introduction
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 cir-
cuits. 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 confi-
dence. The Model 34 is housed in a light-
weight, 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 perma-
nent location.

The Model 34 is intended for use by on-air
broadcast and production support person-
nel. 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 chan-
nel 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
independently 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 produc-
tion 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 tech-
nicians, 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 producers. While
