Atlona Omega 4x2 4K/UHD multiformat matrix switcher - AT-OME-MS42-HDBT

Product Overview

The Atlona AT-OME-MS42-HDBT is a 4x2 multiformat matrix switcher engineered for modern conference rooms, collaboration spaces, and dual-display AV installations. Part of Atlona's Omega Series, this 4K/UHD HDBaseT matrix switcher accepts USB-C, HDBaseT, and two HDMI inputs while delivering independent or mirrored output to HDMI and HDBaseT displays. Integrators specifying a 4x2 matrix switcher with USB hub and HDBaseT extension will find the AT-OME-MS42-HDBT addresses both signal distribution and unified communications in a single 1U half-rack chassis.

Product Description

The Atlona AT-OME-MS42-HDBT is a versatile 4x2 AV matrix switcher with USB-C, HDBaseT, and HDMI inputs, plus independent HDMI and HDBaseT outputs. It is HDCP 2.2 compliant and supports 4K/60 4:4:4 at up to 18 Gbps on local HDMI and USB-C ports, while HDBaseT ports extend 4K/60 4:2:0 video, embedded audio, USB, control, Ethernet, and PoE up to 330 feet (100 meters) over CAT6/6a/7 cable. The USB-C input delivers single-cable connectivity for AV, USB 2.0 data, and up to 60W laptop charging, eliminating the need for separate power adapters in BYOD meeting spaces. An integrated USB 2.0 hub with two Type-A peripheral ports and switching for up to four host PCs makes the AT-OME-MS42-HDBT an ideal centerpiece for Zoom, Microsoft Teams, Cisco Webex, and other unified communications platforms. Selectable AV switching modes allow the HDMI and HDBaseT outputs to operate in mirrored or matrixed configuration, with automatic input selection triggered by hot plug detect or active video presence. The built-in automatic display control feature powers connected displays on and off via TCP/IP, RS-232, or CEC without requiring a dedicated control processor. A balanced analog audio output with +4 dBu nominal gain supports audio de-embedding to external DSP or amplifier systems. The AT-OME-MS42-HDBT is configured and managed via an integrated web server, TCP/IP, RS-232, or Atlona Velocity Device Manager for centralized enterprise-wide administration.

Key Features

• 4x2 Matrix Switching — Independently routes USB-C, HDBaseT, and two HDMI inputs to separate HDMI and HDBaseT outputs for dual-display environments.
• USB-C Single-Cable Connectivity — Carries AV, USB 2.0 data, and up to 60W device charging over a single cable for clutter-free laptop connections.
• HDBaseT Extension to 330 ft (100 m) — Extends 4K/60 4:2:0 video, audio, USB, control, Ethernet, and PoE over CAT6/6a/7 to a remote display or transmitter location.
• 4K HDR Support on Local Ports — HDMI and USB-C inputs and HDMI output support 4K HDR10, Dolby Vision, and HLG at up to 18 Gbps.
• USB Hub and Host Switching — Connects up to four host PCs (three local plus one remote over HDBaseT) with automatic or manual USB host switching.
• Selectable 4K-to-1080p Downscaling — Converts 4K/60, 4K/30, or 4K/24 to 1080p on the HDMI output for compatibility with HD displays and codecs.
• Automatic Display Control — Powers displays on/off via TCP/IP, RS-232, or CEC based on switcher activity, reducing energy costs without a separate control system.
• Balanced Analog Audio Output — De-embeds stereo PCM audio to a 5-pin captive screw connector at +4 dBu for integration with amplifiers and DSPs.
• HDCP 2.2 Compliant — Handles protected content throughout the signal chain while allowing non-protected material to pass to non-compliant endpoints.
• Velocity Device Manager Compatible — Centrally managed alongside other Atlona IP-controllable devices for streamlined multi-room or enterprise-wide deployments.
• 1U Half-Rack Enclosure — Ships with surface mount hardware and rack ears for installation in credenzas, furniture, or standard 19-inch racks.
• TAA and NDAA-889 Compliant — Meets federal procurement requirements for government and education installations.

Technical Specifications

Frequently Asked Questions

Q: What cable types are supported for HDBaseT extension on the AT-OME-MS42-HDBT?

CAT5e supports distances up to 295 feet (90 meters) at 4K/UHD. CAT6, CAT6a, and CAT7 support the full 330 feet (100 meters) at 4K/UHD and 1080p. HDMI inputs and output support a maximum of 15 feet (5 meters) at 4K.

Q: Can the AT-OME-MS42-HDBT charge a laptop through the USB-C port?

Yes. When powered by the included AT-PS-245-D4 power supply, the USB-C port delivers up to 60W for laptop or tablet charging alongside AV and USB 2.0 data. Device charging is not available when the unit is remotely powered over HDBaseT.

Q: How many USB host computers can be connected simultaneously?

Up to four USB host PCs can be connected: two via USB Type-B ports, one via the USB-C port locally, and a fourth remotely over HDBaseT from a compatible Omega Series transmitter. USB host switching can follow AV input selection automatically or be controlled independently.

Q: Does the AT-OME-MS42-HDBT work with Zoom and Microsoft Teams rooms?

Yes. The integrated USB 2.0 hub and extension over HDBaseT up to 330 feet make it well-suited for software-based video conferencing platforms including Zoom, Microsoft Teams, Cisco Webex, and GoTo Meeting. A USB camera, microphone, and speakerphone can all be connected to the hub peripherals.

Q: Is a separate control system required for display power control?

No. The AT-OME-MS42-HDBT includes built-in automatic display control via TCP/IP, RS-232, or CEC. It can power connected displays on when a source is detected and off when the system goes idle, eliminating the need for a dedicated control processor in many applications.

Q: Can the HDMI and HDBaseT outputs show different content simultaneously?

Yes. The unit supports a matrix switching mode where the HDMI and HDBaseT outputs can be assigned to any of the four inputs independently. Alternatively, a mirrored mode sends the same source to both outputs.

Q: What Omega Series transmitters are compatible with the AT-OME-MS42-HDBT HDBaseT input?

Compatible transmitters include the AT-OME-EX-TX, AT-OME-EX-TX-WP, AT-OME-EX-TX-WPC, AT-OME-EX-TX-WP-E, and AT-OME-SW21-TX. Consult Atlona compatibility notes for hardware version requirements on specific models.
