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.
