The U-44 is a compact, 4-in/4-out audio interface that enables you to record and perform wherever you are. Small enough to fit in the palm of your hand, the U-44 comes equipped with the features you need to record 24-bit / 96 kHz audio anywhere.

The U-44 offers the same high-quality, low-noise mic preamps as our acclaimed H5 and H6 Handy Recorders, plus compatibility with Zoom’s Interchangeable Input Capsules for incredible possibilities. Use the U-44 with your PC, Mac, or iPad via USB—or as a standalone AD/DA converter and mic preamp. No other audio interface provides this much versatility, value, and performance.

Wherever you want to record, the bus-powered U-44 forms the perfect centerpiece of your mobile studio. Connect instruments, monitors, and other devices when you’re recording at home—or hook it up to your iPad to make music on the go. If bus power isn’t available, the U-44 can run on just two AA batteries, allowing you to record anywhere.

Note: Requires 2 AA batteries or optional AC adapter for power, plus an Apple iPad Camera Connection Kit or Lightning-to-USB Camera Adapter for connection to iPad.
