The Telex BP-325 Dual Channel Binaural Programmable Beltpack is an advanced, professional intercom interface designed to provide sophisticated two-channel communication with individual stereo program monitoring capabilities. This unit elevates the standard beltpack by integrating programmable functionality and binaural (dual-ear) audio paths, making it ideal for critical roles such as live sports broadcasting, theatrical sound design, and complex event production where operators need to communicate on intercom channels while simultaneously monitoring multiple discrete audio sources. Unlike simpler models, it allows the user to assign each of its two communication channels to specific matrix ports and independently control the level and balance of a separate stereo program feed in their headset. This enables, for example, a sound mixer to converse with stage managers on one channel and the broadcast truck on another, all while critically listening to the main stereo mix or a specific iso feed in both ears.

The core of its programmability lies in the ability to configure the unit’s behavior via an external computer or connected master station. Users can assign custom labels to channels, set default volume levels, adjust microphone sensitivity, and configure the mix between the intercom talk channels and the stereo program audio. The beltpack typically features a backlit LCD or OLED display that shows channel names and status, along with dedicated buttons for channel selection, call signaling, and a multifunction knob for volume adjustment and menu navigation. The audio circuitry is designed for high fidelity, with separate amplifiers for the intercom and program paths to prevent crosstalk and ensure both communication clarity and pristine monitoring quality.

Built to the same rugged standards as the standard BP-325, this programmable version features a durable metal chassis, a locking 4-pin XLR headset connector, and a robust multi-pin system connector for data and power from the intercom matrix. Its binaural output drives both sides of a stereo headset, allowing the program audio to be monitored in true stereo or dual-mono, while the intercom channels are typically mixed to a centered mono image. This combination of programmable control, dual-channel full-duplex intercom, and independent stereo monitoring in a single, portable beltpack makes the Telex BP-325 Dual Channel Binaural Programmable Beltpack an exceptionally powerful tool for audio professionals who require unparalleled situational awareness and communication flexibility in dynamic production environments.
