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 2A 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.
