The Atlona AT-OME-CS31-SA is an AV presentation and collaboration system for classrooms
and conference rooms. It features a 3x1 HDMI
hub.
The HDMI switcher is HDCP 2.2 compliant and supports up to 4K/60 4:4:4 plus HDR formats
for common inputs such as laptops, computers, and document cameras routed to the output
connected to a projector or display. The OME-CS31-SA amplifier delivers either two channels
of 25 watts or a single channel of 50 watts into 4 or 8 ohms. It features one balanced stereo
audio input and two unbalanced stereo audio inputs with independent level control for each. A
balanced stereo line level output allows the mixed signal to be passed to an assistive listening
system or separate amplifier. The OME-CS31-SA includes USB 3.0 interfaces for two host
computers, plus four peripheral devices such as a camera, speakerphone, interactive display,
keyboard, mouse, or storage device.
