Flagship effects built into the console
The SQ5+ introduces four dedicated RackUltra FX engines, bringing processing previously reserved for Allen & Heath’s flagship touring systems into a compact mixer format. Alongside premium reverbs and delays, you also get vocal tuning, harmonisers, saturation, distortion, and advanced pitch processing directly inside the desk. This gives engineers far more creative control without needing external plugins or additional rack units. The mixer still includes eight RackExtra FX engines too, allowing you to run multiple reverbs, modulation effects, and delays simultaneously. Dedicated stereo sends and returns keep routing flexible, helping you build polished mixes for live sound, theatre, worship, broadcast, and streamed productions.
Modern workflow for demanding productions
The updated workflow centres around a larger 9-inch capacitive touchscreen with a redesigned dark GUI that stays easy to read in darker venues and control booths. Navigation feels quicker thanks to the drag-and-drop channel layout, custom naming, and improved visual feedback throughout the interface. Illuminated high-grip encoders make hands-on adjustments easier during fast-paced shows, while the Chromatic metering system provides clear level indication across every strip. Seventeen motorised faders and assignable SoftKeys keep commonly used controls within reach, helping engineers work faster under pressure. The overall experience feels more streamlined and modern, especially for users handling complex live productions or hybrid events.
Expanded mixing for AV and broadcast
The SQ5+ is designed to handle more than traditional live sound. Its expanded bus architecture includes six mono or linkable matrix mixes, making it well suited to installations, livestreaming, multi-room audio, and broadcast feeds. Advanced automatic mic mixing adds even more flexibility for speech-focused applications. Two independent 24-channel AMMs can run simultaneously, or combine into a single 48-channel AMM for larger conferences, council chambers, panel discussions, and education environments. Combined with detailed channel processing, low-latency performance, and comprehensive routing, the SQ5+ adapts easily between front-of-house mixing, monitor duties, installed AV systems, and streamed productions.
Flexible connectivity for scalable systems
The SQ5+ is built to sit at the centre of larger audio systems thanks to its Intelligent SLink connectivity and extensive expansion options. The 128x128 SLink port connects directly to Allen & Heath stage boxes, personal monitoring systems, and compatible consoles, allowing systems to scale as requirements grow. An onboard expansion slot supports Dante, Waves, MADI, and additional SLink cards for integration into complex networked audio environments. USB recording has also been refined for modern hybrid workflows, supporting multitrack recording and playback directly to USB storage or through the built-in 32x32 USB audio interface. Whether you're handling touring productions, installed AV, or broadcast applications, the SQ5+ is designed to integrate cleanly into professional setups.
Expand Your SQ+ System
The Allen & Heath SQ+ range supports a variety of expansion cards, helping you tailor your mixer for recording, broadcast, installed audio, and larger digital audio networks. You can add Dante integration, additional stagebox connectivity, Waves processing, or MADI support depending on your setup requirements.
Each card installs directly into the SQ+ option slot, making it straightforward to adapt your mixer for different live, studio, broadcast, and installed audio environments.
Please Note: Expansion cards are sold separately.
