Allen & Heath SQ5+ 48-channel RackUltra FX Enabled Digital Mixer with DEEP Processing

The Allen & Heath SQ-5-PLUS is a next-generation digital mixing console built around a powerful 96kHz XCVI core, delivering ultra-low latency performance and phase-coherent mixing for professional live sound environments. Designed for owner-operators, mid-sized venues, small touring setups, and high-demand AV applications, it offers exceptional audio quality, flexibility, and system integration in a compact, intelligent format. With its expanded processing power and upgraded user interface, the SQ5+ elevates the already industry-trusted SQ series to a new level of performance and usability.

At its core, the SQ5+ features 48 input processing channels, a stereo main LR bus, and extensive mixing architecture including 12 mono/stereo mix outputs, 6 mono/linkable matrix outputs, 4 FX sends, and 4 dedicated RackUltra FX engines. These advanced processing capabilities are complemented by DEEP processing support, allowing engineers to run high-end channel modeling and effects directly within the console. Connectivity is equally robust, featuring 16 XLR mic/line inputs, 3 stereo line inputs (including TRS and 3.5mm options), 12 XLR outputs, 2 TRS outputs, and a dedicated XLR talkback input for professional communication workflows.

The SQ5+ also introduces a refined hardware design, including a larger 9” touchscreen with an updated graphical interface and a sleek carbon-on-graphite control surface that enhances workflow speed and clarity. Built for demanding live environments, it combines intuitive control with powerful routing and processing flexibility, making it a reliable choice for concerts, installations, corporate AV, and touring applications where performance, speed, and audio fidelity are critical.
