Atlona AT-OPUS-RX41 Four-Input 4K HDR Switcher with HDMI and HDBaseT Inputs

The Atlona AT-OPUS-RX41 is a 4×1 switcher and receiver designed for 4K HDR (High Dynamic Range) video systems. It features three HDMI inputs and one HDBaseT input, providing seamless integration for both local and remote AV sources. Supporting video resolutions up to 4K/UHD at 60 Hz with 4:4:4 chroma sampling and HDMI data rates up to 18 Gbps, the OPUS-RX41 delivers uncompromised image performance and flexibility for modern residential and commercial installations.

The HDBaseT input receives video, audio, control, Ethernet, and power up to 330 feet (100 meters) over standard category cable. The unit also supports advanced HDMI Audio Return Channel (ARC), routing audio from a smart TV through both the TOSLINK and HDBaseT connections for playback through an Opus matrix switcher or local audio system. It includes selectable 4K to 1080p downscaling and HDCP 2.2 to 1.4 down-conversion for compatibility with legacy displays, as well as automatic input selection and remote power capabilities for simplified system design.
