Introducing the Omega OME-CS31-SA

The Atlona AT-OME-CS31-SA AV presentation and collaboration system features three input HDMI switching, 50 watt mixer amplifier, and USB 3.0 hub as well as extensive audio and flexible automation capabilities making it ideal for modern classroom and meeting environments.

AT-OME-CS31-SA Setup and Configuration

This video explains the setup and configuration process for the AT-OME-CS31-SA, AT-OME-CS31-SA-C, & AT-OME-CS31-SA-HDBT.

Details

The Atlona AT-OME-CS31-SA is an Omega™ Series AV presentation and collaboration system featuring AV switching, USB routing, audio mixing, amplification, and control making it ideal for modern classroom and meeting environments.

AV Switching

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.

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 two host devices. Making OME-CS31-SA ideal for use with popular video conferencing and UC (unified communications) platforms.

Audio Mixing and Amplification

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.

Advanced Audio Features

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

Automation and Control

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. Alternatively, the switcher can trigger based on occupancy with the Atlona AT-OCS-900N or another sensor connected to its digital I/O.

If a physical user interface is desired for system operation, the OME-CS31-SA can be controlled by Atlona’s AT-VKP-8E keypad controller or a Velocity™ touch panel control system.

* Consumer Electronics Control (CEC): Atlona does not guarantee the function of CEC with all televisions. We can confirm proper operation with many current Samsung, Panasonic, Sony, and LG TVs. Many manufacturers do not support the CEC “off” command when sent from a source and older TVs use proprietary commands. Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not compatible with the installed displays.

Applications

  • Classrooms – In addition to the AV switching, audio amplification, USB routing, and control needed by modern classrooms, the OME-CS31-SA provides additional features for education environments including ducking program audio for an instructor microphone and muting the system for public address messages.
  • Conference rooms – 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.
