Ideal for creators on the go, the AT-UMX3 runs on USB power and packs versatile functionality into a lightweight, travel-friendly frame.

Channel 2 easily toggles between a Hi-Z input for electric guitars and a stereo line input for synths or keyboards, giving musicians the flexibility they need.

Channel 3 handles loopback audio from your connected computer, letting you integrate background music, gameplay sound, or external audio sources into your stream or recording. With intuitive level controls and crisp audio fidelity, the AT-UMX3 makes professional-grade mixing and broadcasting accessible from virtually anywhere.
