This Atlona AT-HDR-CAT-4 4-Output 4K HDR HDBaseT Distribution Amplifier is a high dynamic range (HDR) distribution amplifier with one HDMI® input and four HDBaseT™ outputs. Each output transmits 4K/UHD video @ 60 Hz with 4:4:4 chroma sampling plus support for HDR formats, multi-channel audio, control signals, and power up to 130 ft. (40 m) or 1080p up to 230 ft. (70 m) over Category 6/6A cable.
The HDR-CAT-4 features sophisticated integration capabilities designed for commercial AV distribution applications including HDMI signal pass-through, audio de-embedding, EDID management, CEC display control, RS-232 and IR control extension, remote power for receivers, and HDBaseT link testing. It offers compatibility with any TCP/IP or RS-232 control system and is housed in a 1U, half-rack width enclosure with external universal power supply. The HDR-CAT-4 is ideal for sending HDR and 4K/60 4:4:4 content to AT-HDR-EX-70C-RX receivers.
The HDR-CAT-4 is part of a family of 4K HDR HDBaseT distribution amplifiers that also includes the HDR-CAT-2 two output, HDR-CAT-8 eight output, and HDR-CAT-4ED four output extended distance models.
