The Clear-Com RM-400A is a professional four-channel remote station designed for fixed-location communication within an analog party-line intercom system. It provides a comprehensive and robust interface for users such as stage managers, lighting directors, or audio engineers who require access to multiple communication channels from a central console or desk position. The station offers four independent channels, each with dedicated volume control, call signaling, and microphone muting, enabling the user to manage communication across different production groups—like stage crew, fly rail, spot operators, and production management—simultaneously and with precision. Its all-metal construction ensures durability for continuous use in the demanding environments of theaters, broadcast studios, and live event control rooms.

A key feature of the RM-400A is its flexibility in audio interface options. While often associated with an integrated gooseneck microphone for hands-free operation, the station also provides a standard headset jack, allowing the user to choose between the built-in mic or a private headset. This versatility makes it adaptable to different user preferences and ambient noise conditions. The station connects to the main intercom system via standard 4-pin XLR connectors for each channel and is line-powered from the system, ensuring reliable operation without the need for separate batteries or power supplies. Bright status LEDs for each channel provide clear visual feedback on call signals and microphone activity.

The RM-400A is designed for straightforward integration and scalability. It can be easily added to an existing Clear-Com party-line system by connecting it to the appropriate channel outputs from a main station or distribution panel. Its four-channel capacity and intuitive layout make it a powerful hub for key personnel who need to oversee and participate in multiple lines of communication. By delivering reliable analog audio performance, extensive channel access, and flexible user interfaces in a durable package, the Clear-Com RM-400A serves as a critical communication asset for coordinating complex live productions where clear, instant, and multi-faceted crew interaction is essential.
