The Crestron DM-TX-4K-302-C is a professional DigitalMedia transmitter designed to send high-resolution video, audio, and control signals from a local source device to a remote receiver or DigitalMedia switcher over a single CAT-type cable. It is commonly deployed in corporate conference rooms, classrooms, training facilities, and collaboration spaces where reliable long-distance signal transport is required. The unit allows source devices such as laptops, media players, and presentation systems to be connected at the table or lectern while the display or switching equipment is located elsewhere in the room or rack.

As part of Crestron’s DigitalMedia ecosystem, the DM-TX-4K-302-C supports modern AV workflows while simplifying cabling and installation. It is engineered for permanent professional installations and integrates tightly with Crestron control systems for automated switching and device control. The transmitter emphasizes signal stability, system compatibility, and ease of integration, making it suitable for standardized enterprise AV deployments where consistent performance and long-term reliability are essential.
