Audio Technica AT-UMX3

The AT-UMX3 from Audio-Technica is the perfect desktop audio mixer for both novices and experienced users. This compact, feature-rich USB mixer delivers high-quality sound for livestreams and various other applications. With a high-performance A/D converter (up to 24-bit/192 kHz) and plug-and-play operation, the AT-UMX3 enables seamless connection to your computer or mobile device, allowing you to produce professional-quality mixes effortlessly.

The AT-UMX3 is an ideal solution for integrating multiple audio sources into a single stream. You can connect a condenser or dynamic microphone (via XLR or ¼" plug), guitar, and keyboard to this versatile, all-in-one interface. The intuitive controls and a pair of connected headphones let you mix the audio from the mic and one instrument into a single, cohesive stream. What you hear in your headphones is exactly what your audience will hear.

For those who want to incorporate background music, game sounds, or other audio into their stream, the mixer’s loopback switch is a standout feature. It automatically combines sound from your computer with live mic and instrument audio, sending the complete stereo mix back to the computer for streaming.

Designed and tested by Audio-Technica’s professional audio engineers, the AT-UMX3 USB mixer includes a USB-C to USB-A cable and a USB-A to USB-C adapter for hassle-free connectivity. Its advanced noise-resistant design effectively prevents unwanted electronic noise from smartphones, Wi-Fi routers, and other sources, ensuring pristine audio quality.
