This Atlona AT-OME-CS31-SA 3-Input Switcher For HDMI Signals, 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 includes a 3×1 HDMI switcher supporting common inputs such as laptops, computers, media players, and document cameras routed to the output connected to a projector or display. It is HDCP 2.2 compliant and supports 4K HDR and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps.
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 ideal for use with popular video conferencing and UC (unified communications) platforms.
Audio Mixing and Amplification: The OME-CS31-SA offers three line inputs for connecting a variety of audio devices. Its onboard mixer supports individual level adjustments of the line inputs, de-embedded HDMI audio, and USB audio. The integrated amplifier delivers either two channels of 25 watts or a single channel of 50 watts into 4 or 8 ohms.
Automation and Control: The OME-CS31-SA 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 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.
