The Telex Audiocom MS-2002 is a central control and power unit designed to serve as the operational heart of a professional two-wire party-line intercom system, commonly utilized in broadcast studios, live event production, and theatrical environments. This integrated master station consolidates critical system functions by combining a full-featured communication station for an operator with a robust, high-current power supply for the entire intercom network into a single rack-mountable chassis. It provides the essential interface for a system director, stage manager, or technical supervisor to communicate across all channels, manage multiple conversations, and monitor system status while simultaneously delivering regulated DC power to up to dozens of beltpacks and remote stations.

Functionally, the unit features two fully independent, programmable communication channels, each with its own dedicated control panel featuring large channel-select knobs, call buttons, and illuminated indicators. This allows the primary operator to engage in separate, simultaneous conversations on different channels—such as communicating with camera crew on one channel while talking to the lighting director on another—or to bridge channels together for all-hands communication. The integrated power supply is engineered for reliability and capacity, providing stable voltage to the party-line to ensure clear audio and consistent performance across the entire system, even when fully loaded with user stations. Advanced features often include isolated auxiliary audio inputs for program feed injection and system diagnostics.

Designed for permanent installation in a standard 19-inch equipment rack, the MS-2002 is built for continuous operation with a focus on operational simplicity and system integrity. Its front panel provides immediate access to all critical controls and status LEDs, while its rear panel hosts terminal blocks for intercom line connections, power input, and auxiliary audio inputs/outputs. By combining the master user station and system power supply into one unit, it simplifies system design, reduces rack space requirements, and enhances overall reliability. The Telex Audiocom MS-2002 is a cornerstone component for establishing a robust, scalable, and professional wired intercom network where centralized control and dependable power distribution are paramount.
