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 H5andH6 Handy Recorders, plus compatibility with Zoom’s Interchangeable Input Capsules for incredible possibilities. Use the U-44 with your PC, Mac, or iPhone/iPad via USB—or as a standalone AD/DA converter and mic preamp. No other audio interface provides this much versatility, value, and performance.
The World is Your Studio
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 iPhone/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.
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 iPhone/iPad.
Can your interface do this?
Thanks to its 10-pin Zoom connector, the U-44 is compatible with all of our interchangeable input capsules (sold separately), representing a powerful field recording setup. Choose from six capsules—X/Y, Shock Mount X/Y, Mid-Side, Shotgun, Stereo Shotgun, and Dual XLR/TRS Combo Input—each with its own unique applications. Record the audience during your live performance, or connect our SSH-6 Stereo Shotgun for dialogue and sound design on your latest film project.
Pristine Recording and Playback
Inspired by our Zoom H-series recorders, the U-44 is equipped with high-performance, low-noise mic preamps that enable recording and playback at resolutions up to 24-bit/96 kHz. You can also use U-44 as a studio-quality headphone amp and listen to your favorite music in full fidelity.
It’s All About Connections
The U-44 features a full array of inputs and outputs so you’ll always be prepared for any recording or live performance. Two combo inputs with independent gain knobs and multi-color level indicators provide flexibility for connecting mics, keyboards, and mixers. 48V phantom power can be supplied to inputs 1 and 2, and input 1 supports Hi-Z input for connecting passive guitars, basses, or other instruments. MIDI I/O jacks enable synchronization with devices like electronic keyboards, controllers, and synthesizer or sampler modules.
Multiple output options—including 1/4”, RCA, and S/PDIF—allow you to connect DJ mixers, speakers, and more. Monitoring your mixes is easy thanks to a dedicated headphone output with independent volume control. The direct monitor knob makes it possible to blend your headphone mix between the input and playback signals—perfect for live electronic music performance and DJ’ing.
Ableton Live Lite
Bundled with Ableton Live Lite, the U-44 has everything the modern music creator needs. This integrated software lets you record tracks quickly and intuitively, enhancing them with studio-quality effects like EQ, compression, reverb, delay, chorus, filter, and more. Plus, Ableton’s performance workflows let you take your music to the stage where you can mix and record live.
