Allen & Heath has announced SQ+, a major extension to the SQ range, introducing RackUltra FX processing, expanded DEEP processing power, and a bigger and bolder interface across three new models: the SQ5+, SQ6+, and SQ7+. At its heart, SQ+ packs the same 48-input, low-latency 96kHz XCVI core that underpins the SQ range, but now with significantly more processing headroom for studio-grade effects and the latest generation of DEEP Add-Ons. The headline addition is four RackUltra FX engines, each with dedicated stereo sends and returns. Developed for the flagship dLive system, RackUltra FX delivers a suite of effects including reverbs, vocal tuning, pitch processors, amp modelling, and saturation. All four engines come as standard on every SQ+ model, with Add-Ons available from the Allen & Heath shop. The user interface is built around a larger 9-inch touchscreen and a new dark GUI for improved clarity in all mixing environments. The range has three frame sizes: the SQ5+ with 17 motorised faders and 16 XLR mic/line inputs; the SQ6+ with 25 faders and 24 XLR inputs; and the SQ7+ with 33 faders and 32 XLR inputs.
