Product Description

The Atlona AT-UHD-EX-70C-RX is an HDBaseT receiver for AV signals up to 230 feet (70 meters) over category cable, with integrated RS-232 and IR control pass-through plus Power over Ethernet capability. Compatible with video signals up to 4K/UHD at 60 Hz with embedded multi-channel audio, the receiver supports 4K HDR10 at 24 Hz with 4:2:0 chroma subsampling and 10-bit color. It is HDCP 2.2 compliant and supports EDID management for proper source-to-display format negotiation. The unit features a compact quarter-rack-width metal enclosure with rear panel I/O ports for uncluttered wire management, making it well-suited for mounting behind flat panel displays and above projectors. It is remotely powered by the AT-UHD-EX-70C-TX transmitter or compatible Atlona switcher via 48V PoE over the HDBaseT link, removing the need for an AC outlet at the display location. Bidirectional RS-232 and IR control signals travel over the same HDBaseT link, enabling control of AV sources and displays without additional cable runs. A 12V-triggered IR input allows integration with standard IR receivers for source control. The included AT-IR-CS-TX IR emitter cable enables IR blasting to connected sources. Multi-channel audio pass-through supports PCM, Dolby Atmos, DTS:X, DTS-HD Master Audio, Dolby TrueHD, and all major Dolby and DTS formats. An included mounting bracket kit facilitates installation in tight spaces. The AT-UHD-EX-70C-RX is compatible with a wide range of Atlona switching products including the UHD-PRO3, UHD-CAT, SW, CLSO, and HDVS-200 Series.
