Soundcraft Ui24R - 24-Channel Digital Mixer/USB Multi-Track Recorder with 10 XLR Combo/10 XLR Mic Inputs and WiFi Control in Black Finish

The Soundcraft Ui24R is a 24-channel digital mixer and USB multi-track recorder that delivers a comprehensive, rack-mountable solution for live sound and recording applications. Designed with flexibility and ease of use in mind, the Ui24R allows wireless control from up to 10 devices via built-in dual-band Wi-Fi, making it possible to manage your mix from anywhere in the venue. With its streamlined design and roadworthy reliability, the Ui24R is ideal for musicians, venues, live engineers, and AV professionals who need a powerful and portable mixing and recording system. The device doubles as a stagebox and is built to work in the most demanding live and studio environments, providing 24 simultaneous inputs, including 10 combo 1/4"-TRS/XLR inputs, 10 XLR mic inputs, 2 line inputs, and 2 digital USB playback channels.

At the heart of the Ui24R are 20 professional-grade, Studer-designed preamps, delivering warm and rich audio quality for live performances and multi-track recording. The mixer integrates industry-leading HARMAN signal processing, including dbx compression and Lexicon reverb, delay, and chorus, allowing users to create polished mixes with ease. Additionally, DigiTech guitar amp modeling provides excellent tone-shaping capabilities, particularly useful when a low stage volume is desired. For live applications, dbx AFS2 automatic feedback suppression is built into all monitor outputs, ensuring a clean and feedback-free mix.

The Ui24R's wireless control capability supports cross-platform compatibility, allowing control via iOS, Android, Windows, Mac OS, and Linux devices without the need for additional apps. The system's dual-band Wi-Fi ensures a reliable connection, even in busy network environments, and up to 10 users can control the mixer simultaneously. This allows band members to adjust their own monitor mixes while the front-of-house engineer manages the audience mix. The Ui24R's intuitive user interface is easily accessed through any web browser, giving engineers and musicians the freedom to mix from anywhere in the venue.

In addition to its mixing capabilities, the Ui24R is a robust multi-track recording system. It allows dual-path recording of all 22 inputs and your stereo mix, both to a USB storage device and a connected computer simultaneously, providing redundancy and peace of mind. The Ui24R can also function as a 24-input, 24-output USB audio interface for recording to your favorite DAW, making it an ideal tool for studio production and live recording.

Housed in a compact 4U rackmount design, the Ui24R is perfect for installations and portable setups. The system offers full recallability of all settings, making it easy to switch between different shows or events. With features such as subgroups, mute groups, view groups, and more, the Ui24R provides comprehensive control over complex mixes, and the ability to save and recall shows and snapshots ensures consistent performance. The Ui24R also includes Ableton Live 10 Lite, a powerful software tool for creating, producing, and performing music, adding even more value to this already feature-packed mixer.
