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

Product Overview

The Atlona AT-OPUS-RX41 is a four-input 4K HDR switcher and HDBaseT receiver designed for whole-house AV systems and residential multi-room AV distribution. Combining three HDMI inputs with one HDBaseT input, this 4K HDR HDMI switcher serves as the ideal local room endpoint for Atlona Opus Series matrix switchers — enabling seamless selection between a centrally distributed AV feed and locally connected HDMI sources such as streaming players, gaming consoles, and Ultra HD Blu-ray players. The AT-OPUS-RX41 supports 4K/UHD at 60 Hz with 4:4:4 chroma sampling, HDR10, Dolby Vision, and HLG, along with selectable 4K to 1080p downscaling for compatibility with legacy HD displays.

Product Description

The Atlona AT-OPUS-RX41 is a 4×1 switcher and receiver that integrates HDBaseT signal reception with local HDMI switching in a low-profile, 1-inch-high enclosure suitable for mounting behind a display or above a projector. The HDBaseT input receives 4K HDR content, control signals, Ethernet, and remote power from an Atlona Opus Series matrix switcher over distances up to 330 feet (100 meters) using Category 6/6A cable, at HDMI data rates up to 18 Gbps. Three HDMI inputs accommodate local sources, allowing a complete whole-house AV room endpoint that can draw from either the distribution matrix or independently connected devices. The OPUS-RX41 supports Dolby Vision at 60 Hz on HDMI inputs (30 Hz on HDBaseT), HDR10 at 60 Hz, and HLG for 60p HDR broadcast formats. Advanced HDMI Audio Return Channel (ARC) routes audio from a smart TV through a TOSLINK optical output for local audio playback, and simultaneously through HDBaseT back to the Opus matrix switcher for zone amplifier connection. HDBaseT control extension enables Ethernet, CEC, IR, and RS-232 signal pass-through, allowing a control system at the OPUS-RX41 to reach back and select inputs or control sources on the matrix switcher, and vice versa. Selectable 4K to 1080p downscaling and HDCP 2.2 to 1.4 down-conversion ensure backward compatibility with existing HD displays. Automatic input selection using hot plug detect and video detection technology simplifies day-to-day operation. A handheld IR remote control for power and input switching is included. The compact, low-profile chassis can be surface-mounted on a wall or shelf using the included hardware, and the unit is field-configurable via an integrated web server or Atlona Velocity Device Manager.

Technical Specifications

Frequently Asked Questions

Q: What matrix switchers is the AT-OPUS-RX41 designed to work with?

The AT-OPUS-RX41 is designed as the primary room endpoint for Atlona Opus Series matrix switchers. It is also compatible with the Atlona UHD-PRO3, UHD-CAT, UHD-EX, and SW Series HDBaseT products for 4K/60 4:4:4 at data rates up to 10 Gbps.

Q: Can the AT-OPUS-RX41 be powered by the matrix switcher without a local power outlet?

Yes. The Remote Power feature allows the OPUS-RX41 to be powered directly by a compatible Atlona Opus Series or UHD-PRO3 matrix switcher over the HDBaseT connection, eliminating the need for a local AC outlet at the display location.

Q: Does the AT-OPUS-RX41 support legacy HD displays?

Yes. The OPUS-RX41 includes selectable 4K to 1080p downscaling and HDCP 2.2 to 1.4 down-conversion, ensuring that 4K HDR sources can be displayed on existing 1080p HDCP 1.4 displays without compatibility issues.

Q: How does the HDMI ARC feature work on the AT-OPUS-RX41?

The Advanced HDMI ARC routes audio return from a smart TV through two paths simultaneously: to the local TOSLINK optical output for connection to a soundbar or AV receiver, and through the HDBaseT output back to the Opus matrix switcher for connection to a zone amplifier in a central equipment rack.

Q: What audio formats does the AT-OPUS-RX41 pass through?

The OPUS-RX41 passes PCM 2.0, LPCM 5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS Digital Surround, DTS-HD Master Audio, and DTS:X over HDMI and HDBaseT. The TOSLINK output supports PCM 2-channel, Dolby Digital, and DTS Digital Surround.
