Free firmware download expands the capabilities of the Ui24R with advanced new features, including Speech AutoMix, Multi-Ducker, Chinese-localization and more

NAMM (Booth #14811), ANAHEIM, Calif.—HARMAN Professional Solutions, the global leader in audio, video, lighting and control systems, including networked AV, today announced the free Soundcraft Ui24R 2.0 firmware update is now available.

The free update includes several significant additions and workflow enhancements to the Ui24R feature set. The Speech AutoMix function automatically reduces the noise floor in panel-discussion or theatre situations by prioritizing the current speaker. The Multi-Ducker feature, designed for radio or TV broadcast workflows, allows for automatic ducking of user-specified sources. Language localization provides the option of setting the browser-based user interface to Chinese.

"Ui24R 2.0 Firmware adds new features and advanced workflow enhancements that enable users to mix with greater flexibility and speed," said Scott Wood, Solutions Manager, Mixing at HARMAN Professional Solutions. "For engineers and mixers working in broadcast or performing arts environments, innovative features like Speech AutoMix and Multi-Ducker make the Ui24R even more powerful and user friendly. This is the fourth free firmware update we've released since the Ui24R debuted last March, demonstrating our commitment to continually expanding the Ui24R’s capabilities."

The Speech AutoMix feature is designed to prevent significant noise-floor increases in situations where multiple mics are open, such as a panel discussion or theatrical production, by automatically prioritizing the current speaker and deprioritizing the other open mics. Speech AutoMix also provides a "weight" compensation for adjusting for stronger or less prominent voices in the group, as well as a single control for modifying the speed of response between channels.

For content creators working in broadcast environments, the new Multi-Ducker feature greatly simplifies the mixing workflow by allowing groups of mic channels to be routed to numbered subgroups. When signal is present in a lower-numbered subgroup, the higher-numbered subgroups are automatically "ducked" and compressed to a lower level. When the people on mics are speaking, the music subgroups will automatically duck their levels, and when the speaking pauses, the music channels return to the same level.

To support the rapidly growing Chinese user-base for the Ui24r, users can now easily switch Ui24R's HTML5  browser-based interface from English to Chinese. This marks the first ever language localization in a Ui product.

The Ui24R digital mixing and recording system delivers flexible I/O, pristine sound quality, intuitive wireless control and roadworthy reliability—all in a streamlined design. The system can be controlled by up to 10 devices via Ethernet or built-in dual-band Wi-Fi, making it possible to control mixing and multitrack recording wirelessly. Renowned Lexicon, dbx and DigiTech signal processing ensures pristine sound, while 20 Studer-designed microphone preamps deliver more professional inputs than any other mixer in its class. The compact, rack-mounted Ui24R is part of the HARMAN Connected PA ecosystem and offers unprecedented control, versatility and power at an incredible value.

The Ui24R v2.0 firmware update is compatible with HTML5 browsers on Windows 7 and 10, Mac, Android, and iOS. For more information, please visit
