Soundcraft Ui12 - 12-Channel Digital Mixer with 4 XLR Combo/4 XLR Mic Inputs and WiFi Control in Black Finish

The Soundcraft Ui12 is a 12-channel digital mixer designed for seamless control via Wi-Fi, offering a range of remote-controlled features and cross-platform compatibility with iOS, Android, Windows, Mac OS, and Linux devices. With its ability to support up to 10 control devices simultaneously, the Ui12 allows musicians, sound engineers, and live performers to manage their mix from anywhere in the venue using smartphones, tablets, or PCs. This mixer is ideal for small to medium-sized live performances, houses of worship, recording studios, and corporate events where flexibility and high-quality sound control are essential.

Equipped with four XLR combo mic/line inputs and four XLR mic inputs, the Ui12 provides eight total mic preamps, all of which are fully recallable and remote-controlled for gain and phantom power adjustments. Additionally, it features two Hi-Z/instrument inputs for direct connection of guitars or basses, a stereo RCA line input for media devices, and a 2-channel USB media player for playback of MP3, WAV, and AIFF formats. The mixer also offers two balanced XLR Aux outputs, two 1/4-inch headphone outputs with independent level control, and balanced stereo XLR and 1/4-inch main outputs for versatile connectivity.

The Ui12 integrates industry-leading HARMAN signal processing, featuring renowned dbx AFS2 feedback suppression, DigiTech amp modeling, and Lexicon effects. Each input channel is equipped with 4-band parametric EQ, high-pass filter, compressor, de-esser, and noise gate for precise sound shaping. Outputs include a 31-band graphic EQ, noise gate, and compressor, along with a real-time frequency analyzer (RTA) on both inputs and outputs. The three built-in Lexicon effects processors offer reverb, delay, and chorus, allowing users to add professional-grade effects to their mix with ease.

For added flexibility, the Ui12 includes subgroups, mute groups, and view groups, all of which can be controlled remotely. It supports full Show/Snapshot recall, allowing users to store and recall entire mix settings, making it perfect for fast setup between different performances or events. The security lockout feature allows administrators to limit access to specific functions or mixes, which is ideal for multi-user environments. The Ui12 also provides independent network interfaces for simultaneous control via both Wi-Fi and Ethernet, ensuring a stable connection in any situation.

In addition to its rich feature set, the Ui12 is housed in a rugged chassis designed to withstand the demands of live performance environments. Its compact size makes it easy to transport, while the integrated Wi-Fi allows for cable-free setup, making it an ideal solution for musicians and sound engineers looking for a powerful and portable digital mixing system.
