Description

The RTS Single Channel Universal Beltpack with A5F headset jack is a compact partyline beltpak designed for intercom systems. It provides a single audio channel for voice communication and integrates automatic wiring detection to match RTS, Audiocom or Clear-Com schemes. The unit is intended for professional broadcast and live production communication chains.

Key features include auto-wiring scheme detection that configures the unit on insertion and an intelligent power management system that reduces power draw. The beltpak supports multiple headset connector options and provides clear visual feedback through an incoming call lamp. These features help streamline setup and operation in multi-user intercom environments.

Technical capabilities include a current pump circuit that monitors cable length versus actual current consumption to maintain reliable voltage across runs. The system supports daisy-chaining and can be powered efficiently so that up to 40 beltpacks may be supplied from a single PS-20 power supply. The beltpak supports dynamic and electret headset microphones via 4-pin or 5-pin XLR connectors.

Connectivity options include the A5F headset jack variant and selectable 4-pin or 5-pin XLR values to match headset wiring. The unit recognizes RTS, Audiocom and Clear-Com formats automatically, avoiding manual jumper changes. Local controls include selectable talk button modes and incoming call lamp indicators for immediate visual status.

Practical applications include studio communications, event production, and field broadcast where reliable single-channel partyline communication is required. The remote microphone kill feature allows an operator or user to mute all beltpaks inaudibly in case of an open microphone. Voice prompts simplify menu navigation and allow quick factory default resets without mechanical switches.

Installation and daily operation are simplified by automatic configuration and voice guidance. The beltpak’s robust power management reduces power feed points and cabling complexity while maintaining audio reliability. Overall, the unit offers practical, field-ready controls and compatibility for professional intercom networks.
