Description
The AT-OME-CS31-SA-C is a compact 3×1 AV switcher that integrates USB-C, HDMI switching, an audio mixer amplifier, and a USB 3.0 hub into a single low-profile enclosure. It simplifies source connectivity and audio distribution in modern AV spaces while providing device charging and data connectivity. The unit is designed to mount behind displays or under furniture to reduce clutter and streamline installations.
The switcher accepts one USB-C input and two HDMI inputs and provides a single HDMI output with 4K/UHD support at up to 60 Hz 4:4:4 on HDMI inputs. An integrated USB 3.0 hub supports two hosts and four peripherals to share cameras, speakerphones, and other USB devices. On-board DSP enables mixing of line inputs, de-embedded HDMI audio, and USB audio to both amplifier and line outputs.
Audio performance includes a selectable 2 x 25 W amplifier into 4 or 8 ohms or bridged 1 x 50 W output, balanced and unbalanced line I/O, and a balanced line output for assistive listening systems. Advanced audio features include Acoustic Echo Cancellation for USB audio, ducking when signal is present on the balanced mic input, and PA mute via contact closure or PA sense. The OME-CS31-SA-C manages EDID and is HDCP 2.2 compliant to preserve source compatibility and content protection.
Connectivity options are comprehensive and include HDMI, USB-C with DisplayPort Alt Mode and up to 60 W power delivery, a USB 3.0 hub, dual Ethernet ports, two RS-232 control ports, and digital trigger I/O. The unit supports HDR10, HLG, and Dolby Vision on HDMI inputs and provides TCP/IP, JSON over WebSockets, Telnet, SSH and HTTP/HTTPS control. Front panel LEDs and an integrated web GUI allow simple status monitoring and configuration.
Typical applications include classrooms and lecture halls where instructor microphones and program audio must be managed, and conference rooms that require mixed USB and local AV sources. The ducking and PA mute capabilities ensure spoken announcements and instructor speech are clearly heard while preserving program audio. The integrated USB hub and host switching streamline hybrid meeting workflows by sharing cameras and audio peripherals between local and remote hosts.
Installation is simplified by the low-profile chassis, included surface mount brackets, captive-screw connectors, and a locking 2 meter USB-C cable. Automatic display control via CEC, IP, or RS-232 and automatic input switching reduce manual operation for end users. The unit is Energy Star qualified and provides a robust, configurable platform for education and corporate AV deployments.
