RTS BP4000A4F Single Channel Universal Beltpack / A4F Headset Jack / Auto-Wiring / Mic Kill

Description

The Single Channel Universal Beltpack is a compact professional intercom user station designed to integrate into partyline systems. It provides essential talk/listen functionality and supports A4F headset connectivity. The unit is built to operate across multiple wiring formats for immediate deployment.

Key features include automatic wiring-scheme detection that configures the beltpack for RTS, Audiocom or Clear-Com formats on plug-in. Intelligent power management reduces power consumption so a single PS-20 power supply can support many daisy-chained beltpacks. A current pump circuit actively monitors cable length versus current to maintain reliable voltage at each unit.

The beltpack offers enhanced talk button control with selectable modes: always on, always off or switching, plus a blinking incoming call lamp for visual feedback. A remote mic-kill function allows any user to send an inaudible mute command to silence all beltpack microphones on the partyline, with override capability. Short voice prompts provide guided menu navigation and an easy factory default reset.

Connectivity options include either 4-pin or 5-pin XLR headset connectors, accommodating a wide range of professional headsets. Both dynamic and electret headset microphones are supported to match different audio requirements. The unit maintains a simple mechanical design for robust field use.

Typical applications include broadcast studios, OB trucks, theater and live event communication where reliable partyline intercom is required. The beltpack’s auto-wiring and power efficiency simplify installation and reduce the need for on-site configuration. Visual and remote controls improve operator workflow in noisy or complex production environments.

Installation is straightforward thanks to automatic format detection and voice-guided menu functions that eliminate internal jumper settings. The rugged housing and industry-standard XLR connectors deliver dependable mechanical and audio performance. Overall, the beltpack provides practical, technician-friendly features that enhance partyline intercom systems.
