Zoom U-24 Portable 2×4 USB Handy Audio MIDI Interface

Zoom U-24 Portable 2×4 USB Handy Audio MIDI Interface

The U-24 features two low-noise microphone preamps with switchable phantom power and XLR-1/4″ combo jacks. Both preamps can handle mic or line inputs, and input 1 sports a Hi-Z switch for when you need to track an electric guitar or bass. Thanks to mix-adjustable zero-latency direct monitoring, stereo 1/4″ main outs, four RCA line outputs, and a 1/4″ headphone port, the U-24 can simultaneously feed speakers and headphones with independent volume control. The headphone output features its own balance knob, which lets you blend computer playback signals 1-2 and 3-4 for customizable cue mixes.
The Go-Everywhere Interface
The bus-powered U-24 packs all the essential tools into a compact form factor that fits in the palm of your hand. Record with mics, instruments, and more at home or on the go—the U-24 is iPhone/iPad compatible and small enough to take anywhere. It can even run on just two AA batteries for recording in the most remote locations.

Proper connectivity and operation with an iPhone or iPad requires separately available accessories—two AA batteries or the Zoom AD-17 AC adapter for power, plus an Apple iPad Camera Connection Kit or a Lightning-to-USB Camera Adapter. A USB Type-B to Type-A cable is included for hookup to your Mac/Windows computer.
Pristine Recording and Playback
Inspired by the popular Zoom H-series recorders, the U-24 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-24 as a studio-quality headphone amp and listen to your favorite music in full fidelity.
Get Connected
The U-24 is equipped with an essential collection of inputs and outputs for streamlined recording. Two XLR/TRS combo inputs with independent gain knobs and multicolor level indicators allow you to connect mics, keyboards, mixers, and more. The 48V phantom power can be supplied to both inputs, and input 1 supports Hi-Z for connecting guitars, basses, or other passive instruments. MIDI input and output jacks allow you to use devices like keyboards, controllers, synthesizers, and drum machines.

Separate TRS and RCA output jacks provide multiple options for connecting DJ mixers, monitors, and other gear. Finally, an independent headphone output with dedicated volume control gives you complete flexibility while monitoring. Each output (1-2 and 3-4) also has its own mute button.
Your Mix, Your Way
The U-24 has flexible monitoring options for dialing in the perfect mix with zero latency. Balance the cue and main out signals when you’re DJing, or create a mix of click track and main out signals during live performances. Each connector and knob is strategically positioned for fast access, so you can set up and control the U-24 with ease.
Ableton Live 9 Lite
Bundled with the U-24, Ableton Live 9 Lite is a powerful DAW program that 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.
Steinberg Cubasis LE
Cubasis LE, a 4-track audio recording/editing/mixing app for iPad with an intuitive touch user interface, is also included with the U-24.
