The RTS SBP 202 is a professional two-channel portable belt pack user station designed for wired party-line intercom systems in broadcast, live production, and theatrical environments. This belt pack serves as a personal communication hub, allowing crew members such as camera operators, stage managers, and technical directors to communicate clearly with the production team over two independent audio channels. It features a rugged, compact metal housing with a durable belt clip, making it easy to wear and operate hands-free. The unit includes a high-quality, noise-canceling microphone with a flexible gooseneck or boom for clear voice transmission, and a headphone output for monitoring the intercom conversation. Its straightforward controls allow users to adjust volume for each channel individually, select which channel to speak on, and activate a call signal to alert other users.

A defining feature of the SBP 202 is its dual-channel capability, which enables communication on two separate party lines. This is essential in complex productions where different departments—such as video, audio, and lighting—need to have separate conversations but also require the ability to cross-communicate when necessary. The user can listen to both channels simultaneously and choose which channel to transmit on, or use a mix-minus feature to prevent echo. The belt pack connects to the main intercom system via a standard 4-pin XLR cable, which carries both audio and power, simplifying setup and ensuring reliable connectivity. Its robust construction is designed to withstand the physical demands of live event production, including being dropped, stepped on, or subjected to cable strain.

The RTS SBP 202 is a cornerstone of professional wired intercom systems, prized for its reliability, audio clarity, and operational simplicity. It empowers production teams with flexible, dependable communication, which is critical for the coordinated execution of live broadcasts, concerts, and stage performances. By providing individual users with control over their listening and speaking channels, it enhances workflow efficiency and situational awareness on busy sets and in chaotic backstage environments.
