The Clear-Com MS-704 is a professional 4-channel main station designed as the central control unit for a wired party-line intercom system, featuring an integrated gooseneck microphone for convenient hands-free communication. This 2RU rack-mountable unit provides four independent, full-duplex communication channels, allowing separate groups such as stage management, lighting, audio, and video crews to hold simultaneous, clear conversations without interference. The inclusion of a high-quality, broadcast-style gooseneck microphone mounted directly on the front panel is a significant feature, enabling the operator—typically a director or stage manager—to communicate naturally without wearing a headset, freeing them to interact with scripts, control panels, or other personnel in the control room while maintaining constant contact with all teams.

Engineered for robust performance in 24/7 operational environments, the MS-704 is built into a durable metal chassis with a comprehensive front-panel interface. Each channel has dedicated controls including a large rotary volume knob, a prominent talk button with an illuminated status indicator, and a call signal button. The unit powers multiple belt packs directly on each channel via standard two-wire cabling, simplifying system infrastructure. It includes advanced audio features such as adjustable sidetone for the headset output, multiple program inputs with level controls, and integrated ducking that automatically lowers the program audio level when intercom communication is active, ensuring that critical instructions are always audible over any background feed.

The MS-704 is designed for permanent installation in broadcast control rooms, theater fly galleries, or live event production centers where reliable, multi-channel communication is the backbone of operations. Its rack-mount form factor ensures it integrates neatly into standard equipment racks. By combining a powerful four-channel main station with the operational convenience of a built-in gooseneck microphone, the Clear-Com MS-704 provides an efficient, intuitive, and professional command console for coordinating complex productions, ensuring that directors and managers have immediate and unambiguous control over all lines of communication.
