Overview

Armed with the Zoom U-24 portable 2x4 USB essential audio/MIDI interface, it's easy for musicians, songwriters, and producers to record two sources simultaneously to their computer, iPhone, or iPad, and integrate MIDI gear, too. At home, outside, or while traveling, the U-24's tactile controls and high-resolution 24-bit / 96 kHz converters help you capture your creativity with quality. Plus, it comes with Ableton Live Lite and the Steinberg Cubasis LE iPad app to provide the software you need to take your music from inspiration to a finished production.
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.
