* 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.
Control Your Mix
With advanced monitoring options, the U-44 lets you dial in your ideal mix. Create a balanced headphone mix between your click track and main out signals during live performances. Or balance the cue and main out signals when you’re DJ’ing. The outputs of channels A and B can be muted, providing even more control. Plus, direct monitoring enables you to hear the live signal you’re recording without latency—simply adjust between the input and computer playback signals to create the perfect mix.
Standalone AD/DA Conversion
When you’re transferring audio, high-quality AD/DA conversion is critical. The U-44 functions in standalone mode as a high-quality mic preamp and AD/DA converter to ensure complete transparency when converting audio formats.
You can choose between a 44.1 or 48 kHz sampling rate for conversion.
