Studio Technologies M32A IFB Plus Talent Amplifier

The Model 32A Talent Amplifier is a self-contained listen-only beltpack unit intended for use by on-air talent or production personnel. It's directly compatible with the Studio Technologies' Model 2A 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 2A'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 2A Central Controller. A source select switch allows audio from either Model 2A channel 1 or Model 2A 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.
