The Clear-Com MS-222 is a professional two-channel main station designed as the central control unit for a wired party-line intercom system, housed in a compact 1RU rack-mountable chassis. This unit provides two independent, full-duplex communication channels, enabling separate groups such as technical crew and production staff to converse simultaneously without interference. Its intuitive front panel features dedicated controls for each channel, including a rotary volume knob, a prominent backlit talk button, and a call signal button, allowing a director or stage manager to easily manage communication with either or both teams. The MS-222 is engineered for reliability in continuous operation, making it an ideal solution for smaller broadcast studios, corporate AV rooms, theater sound booths, or as a zone controller within a larger installation.

A key feature of the MS-222 is its integrated power supply, which can power multiple belt packs directly on each of its two channels via standard two-wire intercom cabling. This self-contained design simplifies system setup by eliminating the need for external power supplies for basic deployments. The main station includes professional audio management features such as a program input with level control, allowing a video feed or audio mix to be fed into the intercom headsets. It also incorporates a ducking function that automatically lowers the program audio level when someone speaks on the intercom, ensuring that critical instructions are clearly heard over any background audio.

Built with a durable metal enclosure, the MS-222 is designed for permanent installation in equipment racks. Its straightforward interface and robust construction ensure ease of use and long-term dependability. By consolidating control, power, and essential audio features into a single space-efficient unit, the Clear-Com MS-222 provides a cost-effective and powerful foundation for professional communication. It delivers the clear, reliable two-way dialogue necessary for precise coordination in live productions, ensuring that all team members remain connected and responsive throughout an event.
