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 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 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 producers. 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.

The Model 34 is compatible with virtually every standard broadcast IFB and party-line intercom circuit. This type of circuit typically uses 3-pin XLR-type connectors for interfacing with connected equipment. 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 in dual-channel systems or channel 1 audio in single-channel systems.
