The Atlona AT-OME-ST31A is a 3×1 switcher and HDBaseT transmitter designed for remote powering, with HDMI and USB-C® inputs.
The OME-ST31A features two-channel audio de-embedding to an analog balanced audio output.
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 1080p @ 60, 30, or 24 Hz is available for the HDMI output when connected to an HD sink.
The OME-ST31A is designed for use 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.
All-in-One Switcher, Controller, and Extender
This switching transmitter can serve as an integral component of a fully automated AV system, with the convenience of automatic input selection and display control.
It can be remotely powered by Atlona HDBaseT-equipped devices. With the optional AT-PS-245-D4 power supply, the OME-ST31A can charge laptops and mobile devices through the USB-C port.
For additional integration convenience, the OME-ST31A features TCP/IP and RS-232 control, RS-232 insertion over HDBaseT, and remote management with Atlona Management System (AMS).
Automatic Display Control
The OME-ST31A provides control to a display through TCP/IP, RS-232, or CEC*, without the need for a separate control system.
This simplifies system design and integration while reducing costs. With automatic display control, the OME-ST31A can trigger a display to power on automatically whenever a laptop or other device is connected.
At the end of the presentation, when the presenter disconnects the laptop, the OME-ST31A forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment.
The OME-ST31A display control capability can also be triggered by an external control system.
The OME-ST31A automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal, as well as active video.
This ensures reliable auto-switching operation for all video sources, including DVRs, DisplayPort / Mini DisplayPort adapters, and other devices that always maintain the HPD line at the 5 volt “high” state but may not be delivering active video.
• Complete system integration – The OME-ST31A and a compatible HDBaseT receiver provide a compact, yet comprehensive and cost-effective integration solution. When installed below a meeting table, the available Pocket™ 3H (AT-PKT-3H) provides convenient tabletop AV cable access for easy BYOD connectivity.
• Larger system applications – The OME-ST31A is ideal for extending AV connectivity from a central equipment rack to a meeting table or lectern, 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 confidence monitor.
