Introduction
Applications
• Complete system integration
The OME-ST31A and a compatible HDBaseT receiver provide a compact, yet comprehensive and cost-eective
integration solution.
• Larger system applications
The OME-ST31A is ideal for extending AV connectivity from a lectern or a conference table to a remote display,
where presenters can easily access the system.
• Auditoriums and lecture halls
This switcher can be used for presenting 4K video content through the projector, while also optimizing for a
1080p condence monitor.
The Atlona AT-OME-ST31A is a 3×1 switcher and HDBaseT transmitter, with HDMI and USB-C inputs. Part of the
Omega™ Series of integration products for modern AV communications and collaboration, the OME-ST31A features
mirrored HDMI and HDBaseT outputs and is HDCP 2.2 compliant. The USB-C input is ideal for AV interfacing with
newer Mac®, Chromebook™, and Windows® PCs, as well as smartphones and tablets. Video signals up to 4K/60
4:2:0, plus embedded audio, control, and Ethernet can be transmitted over HDBaseT up to 330 feet (100 meters).
All inputs and the local HDMI output support 4K HDR and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps.
Additionally, 4K downscaling to 1080 @ 60, 30, or 24 Hz is available for the HDMI output when connected to an HD
sink. Audio de-embedding to a balanced analog audio output enables local sound reinforcement applications.
The OME-ST31A is designed for remote PoE powering, and is compatible with Omega series receivers and
switchers, select HDVS series receivers such as the AT-HDVS-SC-RX scaler, the AT-UHD-EX-100CE-RX receiver, and
other Atlona switchers with HDBaseT inputs.
