When choosing a USB audio switcher for a classroom or conference room, consider the number and types of host inputs, USB peripherals, AV sources, and displays it must connect, along with whether it supports switching between conferencing hosts and routing devices such as cameras and speakerphones. Audio mixing, microphone ducking, public address muting, amplification, line-level output, and control options can also help the system accommodate presentations, lessons, and hybrid meetings.

USB audio switchers connect cameras, speakerphones, microphones, and other conferencing peripherals to an integrated USB hub, typically through dedicated USB ports. The switcher routes those devices to the selected host computer, allowing users to switch peripherals between two host devices for video conferencing and unified communications applications.

When comparing USB audio switchers, review support for USB host and peripheral connections, USB audio routing, and analog line inputs for microphones or other audio sources. Also compare the available outputs, such as de-embedded HDMI audio, line-level output for assistive listening or external equipment, and integrated amplification for connected speakers.

USB audio switchers can integrate with displays through control options such as TCP/IP, RS-232, or Consumer Electronics Control (CEC), and some models can automate display power based on system activity. USB routing between host devices and connected peripherals, such as cameras and speakerphones, also supports unified communications platforms for video conferencing and hybrid meetings.
