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.
