Atlona Omega 4K/UHD Receiver w/Dual HDBaseT inputs, HDRMI input and HDMI output - AT-OME-RX31

Product Overview

The Atlona AT-OME-RX31 is a 3×1 HDBaseT receiver, AV switcher, and 4K/UHD scaler from the Omega Series, designed for conference rooms, active learning classrooms, and multi-source presentation spaces. It accepts two HDBaseT inputs (up to 330 ft / 100 m on CAT6/6a/7) and one local HDMI input, delivers a scaled HDMI output, and integrates automatic display control and room automation features — all without a separate control system. Integrators specifying a 4K HDBaseT receiver with dual inputs, built-in scaler, and automated room control for Omega Series AV deployments will find the OME-RX31 a complete, compact display-end solution.

Product Description

The Atlona AT-OME-RX31 is part of the Omega Series of integration products for modern AV communications and collaboration. It functions simultaneously as a three-input switcher, HDBaseT receiver, and 4K/UHD scaler, combining capabilities that would otherwise require multiple devices. The two HDBaseT inputs each receive video, audio, Ethernet, and power over a single category cable from distances up to 330 feet (100 meters) on CAT6/6a/7, or 295 feet (90 meters) on CAT5e. The local HDMI input — supporting UHD/60 4:4:4 — is ideal for a locally connected wireless collaboration gateway, PC, video conferencing codec, or media player installed near the display. HDCP 2.2 compliance ensures protected content flows from authenticated sources and transmitters. The integrated 4K/UHD scaler supports upscaling and downscaling with selectable frame rate conversion, enabling mixed HD and 4K systems and downscaling 4K sources for hardware video conferencing codecs that require 1080p input. The OME-RX31 can also upsample incoming 4:2:0 video to 4:2:2 or 4:4:4 for displays that do not natively support 4:2:0. Automatic display control via TCP/IP, RS-232, or CEC powers the display on or off based on source activity, and a lamp cooldown mode prevents premature projector restart. Two contact closure relay ports automate motorized screens, display lifts, and shades, while trigger I/O ports allow occupancy sensor integration for fully automatic room operation. A dual-port integrated Ethernet switch reduces the number of network drops required by sharing a single AV LAN connection between the receiver, display, and upstream switcher. Audio de-embedding delivers two-channel PCM to a balanced analog output with five-band EQ, and multi-channel audio formats including Dolby Atmos and DTS:X pass through via HDMI. Three internal test patterns — color bars, crosshatch, and grayscale — facilitate display calibration and troubleshooting. The OME-RX31 also powers up to two Atlona Omega Series transmitters over HDBaseT via IEEE 802.3af PoE. Configuration and firmware updates are managed through the built-in web GUI or Atlona Velocity Device Manager.

Key Features

• Dual HDBaseT Inputs — Switch between two remote HDBaseT source locations — such as a meeting table and a wall plate — up to 330 ft (100 m) on CAT6/6a/7 or 295 ft (90 m) on CAT5e.
• Local HDMI Input (UHD/60 4:4:4) — Third input accommodates a wireless gateway, codec, PC, or media player installed near the display, supporting full 4K/60 4:4:4 without a long cable run.
• Advanced 4K/UHD Scaler with Frame Rate Conversion — Upscales and downscales with aspect ratio control, 4:2:0 to 4:4:4 upsampling, and pass-through bypass mode for optimal image quality on any display.
• HDCP 2.2 Compliant — Passes protected content between authenticated HDCP 2.2 sources and displays; HDCP compliance is software-switchable for non-compliant displays and codecs.
• Automatic Display Control — Controls display power via TCP/IP, RS-232, or CEC on source connect/disconnect, with adjustable projector lamp cooldown mode — no separate control system required.
• Two Contact Closure Relay Ports — Automate motorized screens, display lifts, and shades based on system power state, with normally-open toggle and pulse modes.
• Trigger I/O for Occupancy Sensing — Works with occupancy sensors to automatically place the system in standby and power off the display when the room is unoccupied.
• Dual-Port Integrated Ethernet Switch — Shares a single AV LAN network drop among the receiver, display, and upstream HDBaseT switcher, simplifying installation wiring.
• Audio De-Embedding with 5-Band EQ — Extracts two-channel PCM audio to a balanced analog output (+4 dBu nominal, +20 dBu headroom) with independent volume/mute controls and five-band EQ.
• Multi-Channel Audio Pass-Through — Passes PCM 2.0/5.1/7.1, Dolby Digital, Dolby TrueHD, Dolby Atmos, DTS Digital Surround, DTS-HD Master Audio, and DTS:X via HDMI output.
• PoE Source over HDBaseT (IEEE 802.3af) — Powers up to two Atlona Omega Series transmitters over HDBaseT, removing the need for local AC power at transmitter locations.
• Low-Profile 1.02-Inch Enclosure — 26 mm high for installation in confined spaces behind displays and above projectors; rack-mountable with optional AT-RACK-1RU shelf.

Typical Applications

• Conference rooms and meeting rooms requiring switching between two remote table or wall HDBaseT transmitters plus a local wireless gateway
• Active learning classrooms receiving AV from two student pod transmitters with 4K display scaling
• Corporate boardrooms with motorized screen or display lift automation via contact closure relays
• Lecture halls with occupancy-based automatic system power-on and power-off
• Omega Series AV system display-end receiver paired with AT-OME-ST31A, AT-OME-SW21-TX, or CLSO/HDVS Series switchers
• Hospitality and higher education spaces with mixed 4K and HD source environments requiring transparent scaling

Technical Specifications

Frequently Asked Questions

Q: What is the difference between the two HDBaseT inputs on the AT-OME-RX31?

Both HDBaseT inputs are functionally identical — each receives 4K/UHD video, embedded audio, Ethernet, and bidirectional control over a single category cable. The two inputs allow the OME-RX31 to switch between two physically separate source locations, such as a meeting table transmitter and a wall-plate transmitter, giving presenters flexibility in where they connect.

Q: What transmitters are compatible with the AT-OME-RX31?

The OME-RX31 is compatible with Atlona Omega Series transmitters including the AT-OME-TX11-WP, AT-OME-ST31A, and AT-OME-SW21-TX, as well as CLSO and HDVS Series presentation switchers with HDBaseT outputs, and UHD-EX Series HDBaseT transmitters.

Q: Does the AT-OME-RX31 support HDR content?

Yes, the OME-RX31 supports HDR10, Hybrid Log-Gamma (HLG), and Dolby Vision at 60 Hz, but only on the HDMI input and HDMI output. HDR is not passed through the HDBaseT inputs.

Q: Can the OME-RX31 downscale 4K sources for video conferencing codecs requiring 1080p input?

Yes. The integrated scaler can downscale 4K/UHD content to 1080p or any other supported output resolution, making it straightforward to feed a hardware video conferencing codec that does not accept 4K input while the display itself receives full 4K output.

Q: How does the occupancy sensor trigger work?

The Trigger I/O port (4-pin captive screw) accepts a signal from a compatible occupancy sensor such as the Atlona AT-OCS-900N. When the sensor detects that the room is unoccupied, the OME-RX31 can be configured to enter standby mode and send a power-off command to the display automatically, with no control system or user action required.

Q: Does the AT-OME-RX31 need a full-size rack bay?

No. At only 1.02 inches (26 mm) high, the OME-RX31 is designed for surface mounting behind displays, above projectors, or in furniture. For rack installations, it mounts on the optional AT-RACK-1RU rack shelf.

Q: Where can I purchase the AT-OME-RX31?

The AT-OME-RX31 is available from Creation Networks at creationnetworks.net, an authorized Atlona Omega Series reseller serving commercial AV integrators.
