The AT-OME-CS31-SA-HDBT is an AV presentation and collaboration system featuring a 3×1 switcher with HDMI and HDBaseT inputs, 50 watt mixer amplifier, and USB routing.
Ducking lowers program audio levels when the teacher speaks into their microphone connected to the balanced line input. Mute audio when a PA message is detected or with a contact closure. Both features ensure important lesson material and announcements are heard clearly.
Automate system operation based on switcher activity, integration with occupancy sensors, or use with a Velocity control system.
The AT-OME-CS31-SA-HDBT is an AV presentation and collaboration system featuring a 3×1 switcher with HDMI and HDBaseT inputs, 50 watt mixer amplifier, and USB 3.0 hub. These combined with extensive audio and flexible automation capabilities make 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.
Advanced Audio Features
The OME-CS31-SA-HDBT also includes audio integration capabilities for classroom environments that ensure lesson material and announcements are heard clearly including:
- Ducking – Lowers the level of program audio sources when signal, such as a teacher microphone, is present on the balanced line input.
- PA Mute – The audio output of the switcher can be muted when an announcement is detected on the school public address system or via contact closure from a third-party system.The OME-CS31-SA is an all-in-one solution for hybrid meeting spaces that need AV switching, audio amplification, USB routing, and display control.
- Line output – In addition to the amplifier, all switcher audio is also routed to the line output which can be connected to an assistive listening system
Automation and Control
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.
