Atlona 3x1 HDMI/USB Switcher with Audio Mixer Amplifier & USB Hub

Atlona AT-OME-CS31-SA Overview

This 3x1 HDMI/USB Switcher from Atlona is a comprehensive AV solution tailored for classrooms and conference rooms, facilitating seamless presentation and collaboration. It offers remote and local AV source switching, a mixer/amplifier, and a USB hub. The switcher features two HDMI and one USB-C input, Ethernet, power, control, and USB 2.0 data extension up to 330'. Connected devices like laptops and document cameras are seamlessly routed to the HDMI output linked to a projector or display.

The integrated mixer/amplifier delivers either two channels of 25W or a single channel of 50W into 4 or 8 ohms, featuring a balanced stereo audio input and two unbalanced stereo audio inputs with individual level control. A balanced stereo line-level output enables the mixed signal to be transmitted to assistive listening systems or separate amplifiers.

The unit's USB system integrates two local USB hosts and supports connections for up to four peripheral devices, including cameras, speakerphones, interactive displays, keyboards, mice, or storage devices. Designed with educational settings in mind, the versatile device incorporates unique features such as ducking, which automatically reduces the volume of other audio sources when the presenter speaks into their microphone, and PA sense, which mutes the amplifier output upon detecting activity on the school's public address system. These functions ensure that crucial lesson material and announcements are conveyed clearly.

For control purposes, dual Ethernet ports and two RS-232 ports enable automated operation by the switcher itself or integration with Velocity and other third-party control systems. The sleek and compact enclosure allows flexible mounting options, such as behind a display, under a desk, or on a table.
