This Atlona AT-OME-CS31-SA-C 3-Input USB-C & HDMI Switcher, Mixer Amplifier & USB Hub is an Omega™ Series AV presentation and collaboration system featuring AV switching, USB routing, audio mixing, amplification, and control making it ideal for modern classroom and meeting environments.
AV Switching: The OME-CS31-SA-C includes 3×1 switching between one USB-C input, two HDMI inputs, and one HDMI output. The USB-C input supports AV, data, and device powering up to 60 watts over a single connection, reducing cable clutter.
USB Routing: The system features a four port USB hub for connecting cameras, speakerphones, interactive displays, and other devices as well the ability to switch them between two host devices. Making OME-CS31-SA-C ideal for use with popular video conferencing and UC (unified communications) platforms.
Automation and Control: The OME-CS31-SA-C can provide control to a display through TCP/IP, RS-232, or CEC*, without the need for a separate control system. With automatic display control, the switcher 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 OME-CS31-SA-C forces the display to power off. Alternatively, the switcher can trigger based on occupancy with the Atlona AT-OCS-900N or another sensor connected to its digital I/O.
