Description

The AT-OME-MH21-CP is a compact two-input presentation switcher designed to simplify AV connectivity in meeting and collaboration spaces. It accepts USB-C and HDMI sources and outputs HDMI video while providing an integrated USB 3.0 hub and device charging. The product automates display control and input switching to reduce user interaction and speed meeting start times.

The switcher supports native 4K/UHD at 60 Hz with 4:4:4 chroma sampling and HDR formats including HDR10, HLG, and Dolby Vision at 60 Hz. It features selectable downscaling to 1080p for compatibility with legacy displays and passes multi-channel audio formats. The USB-C port carries AV plus USB data and supplies up to 60 watts of device charging to connected laptops and tablets.

Built-in video processing supports 4K to 1080p conversion at 60, 30, or 24 Hz and maintains a 600 MHz pixel clock for high-bandwidth signals. HDCP 2.2 compliance ensures protected content can be routed between authenticated devices while EDID management preserves expected resolutions and audio formats. Audio de-embedding provides balanced 2-channel analog output for direct connection to amplifiers or DSPs.

Connectivity includes one HDMI input, one USB-C AV input, one HDMI output, two USB Type-A peripheral ports, one USB Type-B host port, LAN, RS-232, IR pass-through and CEC over HDMI. The integrated USB hub supports USB 3.0 speeds for cameras and speakerphones while the USB Type-B and USB-C host options enable flexible PC connections. Network and serial control enable integration with facility management and AV control systems.

The OME-MH21-CP is suited to huddle rooms, small meeting rooms, and BYOD collaboration points where fast handoff between presenters is required. It supports popular UC platforms through USB peripheral sharing and automatic switching, so presenters can join a meeting and have the display and conferencing peripherals engage immediately. The unit can be hidden under a table or installed in furniture thanks to its low-profile 1.02 inch height.

Installation is straightforward with on-device web configuration, TCP/IP and RS-232 control, and compatibility with Velocity Device Manager for centralized administration. Front-panel LEDs provide quick status checks and field-updatable firmware keeps the device current. The rugged metal enclosure and included external power supply deliver a reliable, professional AV integration solution.
