The Extron DTP HDMI 330 Rx is a professional receiver unit within Extron's Digital Twisted Pair (DTP) ecosystem, designed for the long-distance extension of HDMI signals over a single CATx cable. This receiver works in conjunction with a compatible DTP transmitter to receive high-definition video, embedded multi-channel audio, and bidirectional control signals that have been transmitted from a source located up to 330 feet (100 meters) away. Its core function is to reconstruct the original HDMI signal with full fidelity at the display location, supporting resolutions up to 4K at standard frame rates, including HDR content, making it suitable for demanding commercial AV installations in boardrooms, classrooms, digital signage networks, and healthcare facilities where sources and displays are often separated by significant distances.

The receiver incorporates Extron's advanced signal reconditioning technology, which equalizes, re-clocks, and re-drives the incoming signal to ensure a robust, stable output that is free from artifacts like sparkles, dropouts, or sync loss. This processing is critical for maintaining image integrity over long cable runs where signal degradation is inevitable. In addition to the primary HDMI output, the unit often provides a local HDMI output for daisy-chaining to another display or for local monitoring. A key feature of the DTP system is the integration of bidirectional control channels, allowing for the transmission of RS-232, infrared (IR), and Ethernet signals between the transmitter and receiver locations over the same CATx cable. This enables centralized control of source devices and displays from the receiver end, simplifying system design and operation.

Housed in a compact, metal enclosure, the DTP HDMI 330 Rx can be discreetly mounted behind a display or within an equipment rack. It is typically powered via the DTP cable itself (using Power over DTP) from the transmitter or via an optional local power supply, offering installation flexibility. The receiver is designed for seamless integration with Extron's control systems and switchers, supporting features like EDID (Extended Display Identification Data) management to ensure reliable source compatibility. By providing a reliable, high-performance extension solution over low-cost, readily available structured cabling, the Extron DTP HDMI 330 Rx eliminates the limitations of standard HDMI cables, enabling flexible, scalable, and future-proof AV system designs that maintain the highest signal quality over extended distances.
