Th Evolution by Vanco EVRXDSC 4K HDR HDBaseT™ Receiver with POC, Downscaling, ARC, IR and RS-232, allows extension of 4K 60Hz, 4:4:4 Chroma Subsampling, and HDR up to 131ft/40m and 1080p up to 230ft/70m over a single Cat6 cable. PoC (Power over Cable) allows the EVRXDSC to be powered over Cat6 from the matrix unit. For control, features IR pass-through to be able to control either sources and/or displays, as well as RS-232 pass-through for 3rd party integration. Audio Return Channel (ARC) capable when utilizing with the PRO matrix units, passing audio from the connected displays via HDMI or via the optical input, and broken out at the matrix unit, with an additional optical audio port for audio extraction on the EVRXDSC itself. Able to downscale from 4K to 1080p, a perfect solution for multiple resolution displays, without downgrading the resolution on all outputs. The EVRXDSC is compatible with the Evolution EVMX4X3, EVMX8X6, EVMX44PRO, and EVMX88PRO matrix units.The EVRXDSC is a step up from the EVRXHD2, with all the same features plus more, including RS-232 pass-through, ARC, audio extraction, and downscaling. Both receivers can be mixed and matched with compatible Evolution matrix units, resulting in a flexible and modular matrix switching system for any application! 4K HDR HDBaseT™ Receiver with POC, Downscaling, ARC, IR and RS-232 Supports HDMI resolutions up to 4K 60Hz, 4:4:4 chroma sampling and HDR Extends 4K 60Hz 4:4:4, and HDR10 up to 131ft/40m and 1080p up to 230ft/70m over a single Cat6 cable Ability to downscale 4K to 1080p Audio extraction with digital optical audio breakout Supports ARC with Evolution EVMX44PRO and EVMX88PRO matrix units via HDMI or digital optical audio input 18Gbps high bandwidth Features Power over cable (POC) Technology, which provides power for the receivers resulting in easy installation Bi-directional IR and RS-232 pass-through for control Compatible with the Evolution EVMX4X3, EVMX8X6, EVMX44PRO and EVMX88PRO matrix units Dimensions: 5.5" W x 0.8" H x 3.3" D
