Audio-Technica AT-UMX3WH USB audio mixer, White

Compact desktop USB audio mixer

The Audio-Technica AT-UMX3WH is a compact USB audio mixer designed for livestreaming and desktop production. It connects to a computer or mobile device through USB-C with plug-and-play operation and no special drivers required. The unit draws bus power at 5 V and 500 mA, consuming a maximum of 2.5 W. High-performance A/D conversion reaches 24-bit and 192 kHz for clear sound capture.

Inputs and outputs for a streaming setup

A single XLR/TRS combo jack accepts a microphone with switchable phantom power, while two 6.3 mm jacks handle high-impedance guitar and stereo keyboard sources. A USB stereo input brings computer audio into the mix, and a loopback switch merges everything into one stream sent back to the host. Monitoring is provided through a 3.5 mm headphone output with its own level control, letting you hear exactly what the audience hears.

Replaces a basic interface or software mixing

This mixer upgrades from a simple USB audio interface by adding hardware gain, phantom power and zero-latency monitoring in one box. It also removes the need for a separate loopback cable or virtual audio routing software when combining mic, instrument and system sound. The step up is worthwhile when you want tactile control over multiple live sources without installing extra drivers or running additional power supplies.
