This Atlona AT-OME-ST31A 3-Input Switcher & HDBaseT Transmitter With USB-C & HDMI Inputs is a 3×1 switcher and HDBaseT transmitter designed for remote powering, with USB-C and HDMI 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. See the Related Products tab for specific product compatibility.
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 Velocity Device Manager.
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.
