AT-OPUS-68M
The Atlona AT-OPUS-68M is part of the Opus™ Series of HDMI® to HDBaseT™ matrix switchers for high dynamic range (HDR) formats. The 6x8 matrix switcher is HDCP 2.2 compliant and
support 4K/UHD video @ 60 Hz with 4:4:4 chroma sampling, as well as HDMI data rates up to 18
Gbps. The Opus Series enables exible routing to HDBaseT outputs plus two additional HDMI
outputs, and is compatible with the Atlona AT-OPUS-RX receiver or AT-JUNO-451-HDBT switcher for transmission of HDMI, Ethernet pass-through, and bidirectional IR and RS-232 control
signals up to 330 feet (100 meters) over CAT6a/7 cable. Visually lossless VESA Display Stream
Compression (DSC) enables HDR and 4K/60 4:4:4 signal extension over HDBaseT with little to
no latency. Opus matrix switchers are equipped with a comprehensive host of audio and control
system integration features, making them ideal for a wide range of residential and commercial
applications requiring multi-zone AV distribution.
