The U-44 from Zoom is a compact, 4-in/4-out audio interface with 48V phantom power that provides all of the essential tools you need for recording and performing high-resolution, 24-bit/96 kHz audio anywhere you go. It can be used to connect to your Mac or Windows computer, or iPad* via USB, to record with mics, instruments, and more.
The U-44 interface uses the same high-quality, low-noise preamps as the Zoom H5 and H6 handy recorders. It features two TRS/XLR combo jacks for inputs, in/out S/PDIF Optical Toslink and S/PDIF Coaxial on RCA, MIDI In/Out, two TRS 1/4" unbalanced jack outputs, RCA line-level outputs and a standard stereo headphone jack. In addition, it is powered by two AA batteries, providing up to four hours of continuous operation with phantom power turned off. The U-44 includes a download code for Ableton Live 9 Lite software to get you started right away.
Purchasers can also register for a free download of a special version of Pro Tools | First, which contains a valuable collection of twenty-one AAX audio software plug-ins.
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 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.
Zoom 10-Pin Connector
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, Shockmount X/Y, Mid-Side, Shotgun, Stereo Shotgun, and Dual XLR/TRS Combo Input—each with its own unique application. 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 the Zoom H-series recorders, the U-44 is equipped with high-performance, low-noise mic preamps (-119.5 dB EIN) 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.
Get Connected with the U-44
The U-44 features a full array of inputs and outputs so you'll always be prepared. 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, and other instruments. MIDI I/O enables you to use electronic keyboards, controllers, synthesizers, and drum machines.
Multiple Output Options
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.
