Audio-Technica AT-UMX3 USB audio mixer

Desktop USB mixer for streamers and podcasters

The Audio-Technica AT-UMX3 is a compact desktop audio mixer built for live streaming and podcasting. It combines a high-performance A/D converter supporting up to 24-bit/192 kHz resolution with plug-and-play USB connectivity. The unit weighs 0.75 pounds and measures 8.07 by 8.07 by 2.68 inches, making it a small-footprint addition to any content-creation desk. It ships new with a USB-C to USB-A cable and a USB-A to USB-C adapter included.

Check your mic, instrument and device ports

Before ordering, verify that your microphone uses an XLR or 6.3 mm plug to match the Neutrik combo jack, which provides 48 V phantom power for condenser models. Confirm whether your instrument needs the switchable Hi-Z setting for guitar or bass, or the stereo line input for keyboards. Ensure your computer, smartphone or tablet has an available USB-A or USB-C port for the supplied cables, as the mixer draws power directly from the host device via corded electric operation.

Loopback and monitoring change the workflow

The built-in loopback function routes system audio from a Windows PC or Mac directly into the mix, letting you blend game sound or playback tracks without extra cables. A dedicated headphone output provides real-time monitoring of the combined microphone and instrument signals. The advanced noise-resistant design reduces unwanted pickup from nearby smartphones, Wi-Fi routers and other electronic sources, so the recorded stream stays clean. Bundled connectivity adapters remove the need to purchase separate dongles for different host ports.
