The AT-OME-CS31-SA is an AV presentation and collaboration system featuring a 3×1 HDMI switcher, 50 watt mixer amplifier, and USB 3.0 hub.
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 OME-CS31-SA includes a 3×1 HDMI switcher supporting common inputs such as laptops, computers, media players, and document cameras routed to the output connected to a projector or display. It is HDCP 2.2 compliant and supports 4K HDR and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps.
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 two host devices. Making OME-CS31-SA ideal for use with popular video conferencing and UC (unified communications) platforms.
The OME-CS31-SA 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 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.
- 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
The OME-CS31-SA 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 forces the display to power off.
