The perfect desktop audio mixer for novices and experienced users alike, the AT-UMX3 is a compact, feature-rich USB mixer that delivers high-quality sound for livestreams and other applications. Featuring a high-performance A/D converter (up to 24-bit/192 kHz) and plug-and-play operation, the AT-UMX3 lets you connect to your computer or mobile device to easily produce professional-quality mixes.

The AT-UMX3 is the simple solution for feeding multiple audio sources into a stream. Connect a condenser or dynamic microphone (with XLR or ¼" plug), guitar, and keyboard into this handy, all-in-one interface, then use the intuitive controls and a pair of connected headphones to mix the audio from the mic and one instrument into a single stream. Your mix will be sent to your stream audience exactly as you hear it.   

If you’re looking to incorporate background music, game sounds, or other audio into your stream, you’ll appreciate the mixer’s loopback switch, which automatically mixes sound from your computer with the live mic and instrument audio – and outputs the complete stereo mix back to the computer for streaming.

Designed and tested by Audio-Technica’s pro audio engineers, the AT-UMX3 USB mixer comes with a USB-C to USB-A cable and USB-A to USB-C adapter for hassle-free connectivity, and features an advanced noise-resistant design to prevent the pickup of unwanted electronic noise from smartphones, Wi-Fi routers, and other sources.

The feature-rich AT-UMX3 makes it easy to mix all your livestreaming audio elements and monitor the results – so you can be confident the mix is right.
