Description
The AT-OME-CS31-SA is an integrated AV presentation and collaboration system that combines a 3×1 HDMI switcher, USB 3.0 hub and onboard amplifier into a single low-profile enclosure. It routes HDMI video and audio, mixes multiple analog and digital audio sources, and supplies amplified audio for small rooms. The unit supports 4K/UHD signals and modern HDR formats for high-quality display output.
Key features include three HDMI inputs and one HDMI output, a USB hub with two host ports and four peripheral ports, and a selectable stereo amplifier delivering 2 x 25 watts or bridged 1 x 50 watts. The system mixes de-embedded HDMI audio, USB audio and three line inputs while providing Acoustic Echo Cancellation and ducking for microphone priority. It also supports PA mute and automatic display control via activity, occupancy or control interfaces.
Video performance supports 4K/UHD at 60 Hz with 4:4:4 chroma, HDCP 2.2 compliance, and HDR10, HLG and Dolby Vision metadata passthrough. Audio handling includes HDMI pass-through of multichannel formats, 24-bit audio up to 192 kHz sample rates, and balanced and unbalanced analog I/O. Onboard DSP provides mixing, EQ and echo cancellation to optimize room audio performance.
Connectivity is extensive with three HDMI inputs, one HDMI output, two USB type B host ports, four USB type A peripheral ports, balanced and unbalanced analog inputs and outputs, LAN ports and two RS-232 ports. Triggering and automation options include CEC, IP control, RS-232, digital I/O and PA sense trigger. The integrated network switch enables a single AV LAN connection to control both the switcher and a display.
Typical applications include classrooms and small conference spaces that require HDMI switching, USB device sharing and amplified audio in a single device. The ducking function lowers program audio automatically when an instructor microphone signal is present and PA mute allows school announcements to override system audio. The USB hub supports cameras and speakerphones for unified communications workflows.
Installation is simplified by a compact low-profile chassis suitable for mounting behind displays or under furniture and an external universal power supply. Auto-switching, EDID management and a web-based GUI streamline setup and configuration. The unit is Energy Star qualified and includes captive-screw connectors and surface-mount brackets to support neat and reliable installations.
