This Atlona AT-OME-CS31-SA-HDBT 3-Input HDBaseT & HDMI Switcher, Mixer Amplifier & USB Hub is an Omega™ Series AV presentation and collaboration system featuring AV switching for local and remote sources, USB routing, audio mixing, amplification, and control making it ideal for modern classroom and meeting environments.
AV Switching: The OME-CS31-SA-HDBT includes 3×1 switching between one HDBaseT input, two HDMI inputs, and one HDMI output. The HDBaseT input supports extension of video up to 4K/60 4:2:0, plus embedded audio, control, Ethernet, and USB over distances up to 330 feet (100 meters). The HDMI inputs support 4K HDR and 4K/60 4:4:4. Extension is helpful in applications where a source is remotely located, such as at an instructor’s lectern in the room, or if the switcher is mounted by a projector.
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 remote and local host devices. Making OME-CS31-SA-HDBT ideal for use with popular video conferencing and UC (unified communications) platforms.
Audio Mixing and Amplification: The OME-CS31-SA-HDBT 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.
The OME-CS31-SA-HDBT 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-HDBT 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.
