About the AMX DX-RX DXLink HDMI Receiver
The AMX DX-RX is a professional-grade receiver module designed for the DXLink system, AMX's proprietary digital media distribution platform for high-definition audio, video, and control signals over standard CATx cable. This receiver is installed at the display location, where it receives encoded signals from a compatible DXLink transmitter over a single CAT6a/7 cable and decodes them into native HDMI video, multi-channel audio, and bidirectional control data. Its primary function is to enable the extension of high-resolution video sources—including 4K UHD content—over long distances (up to 330 feet/100 meters) without signal degradation, making it a cornerstone technology for large-scale AV installations in corporate, education, government, and hospitality environments.
The receiver supports a comprehensive suite of signal types, delivering pristine video up to 4K resolution with support for HDR and HDCP 2.2 content protection. It also handles embedded digital audio, discrete analog audio, and bidirectional serial (RS-232/RS-422) and infrared (IR) control signals, allowing users to remotely operate source devices from the display location. The unit is typically configured and monitored through AMX's NetLinx programming environment, enabling seamless integration with AMX touch panels and automation systems for a unified room control experience. Advanced features like EDID management, automatic cable equalization, and real-time system diagnostics ensure reliable performance and simplify troubleshooting.
Housed in a compact, modular enclosure, the DX-RX can be installed behind a display, in a furniture podium, or within an equipment rack using a dedicated mounting frame. It is often paired with a DXLink transmitter (DX-TX) to create a complete point-to-point extension system, and multiple units can be deployed across a network of displays fed from a central DXLink transmitter chassis. For system integrators designing robust, scalable, and high-performance AV distribution networks, the AMX DX-RX receiver provides a reliable, feature-rich endpoint that maintains signal integrity over infrastructure-grade cabling while integrating comprehensive control capabilities.
