Allen & Heath SQ7+ 48-Channel Digital Mixer

When productions grow larger and workflows become more demanding, engineers need a control surface that keeps critical channels, mixes and routing decisions immediately within reach. The Allen & Heath SQ7+ 48-channel digital mixer is designed for high-channel-count live sound, installed audio and touring environments that require expansive hands-on control without sacrificing processing speed or routing flexibility. Built around Allen & Heath’s 96kHz XCVI FPGA core, the SQ7+ delivers ultra-low latency performance, phase-coherent mixing and extensive onboard processing for complex productions. A redesigned 9" capacitive touchscreen interface, integrated RackUltra FX engines and Allen & Heath’s DEEP processing architecture provide advanced channel shaping and workflow customization directly within the console. With 33 motorized faders, expanded local connectivity and a full-scale control surface layout, the SQ7+ is built for engineers managing demanding front-of-house, monitor and multitrack production workflows.

96kHz XCVI Processing With Ultra-Low Latency

At the center of the SQ7+ is Allen & Heath’s XCVI FPGA processing core, operating at 96kHz with a system latency of less than 0.7 ms for highly responsive live mixing and monitor applications. The engine supports 48 input processing channels alongside stereo main LR, 12 configurable mono/stereo group and aux mixes, four FX sends and six linkable matrix outputs, giving engineers the flexibility to manage large productions with confidence. By maintaining phase alignment and coherence across the signal path, the SQ7+ preserves clarity and stereo imaging even during demanding routing and high channel-count scenarios. Whether managing front-of-house, monitors or multitrack playback sessions, the console’s processing architecture is designed for consistent operation under professional touring and installed audio workloads.

RackUltra FX and Integrated DEEP Processing

The SQ7+ expands the platform’s processing capabilities with eight internal FX engines and four dedicated RackUltra FX engines with dedicated stereo return channels, featuring advanced Allen & Heath algorithms designed for modern live production. Effects such as Spaces Reverb, Plate Reverb, Saturator and Amp+Cab processing provide studio-style depth and tonal shaping directly within the console, reducing reliance on external processors and outboard racks. The mixer also supports Allen & Heath DEEP processing, allowing engineers to integrate premium compressor, preamp and channel processing models directly into input and mix channels without adding additional latency. Advanced vocal tools including Vocal Tuner, Vocal Shifter and harmonizer processing further expand the console’s utility for contemporary live performance, theater and worship applications.

Large-Format Workflow With Expanded Surface Control

Designed for engineers who require immediate access to larger channel counts and mix layers, the SQ7+ features 33 motorized 100 mm faders arranged across six customizable channel strip layers for extensive simultaneous control during fast-paced productions. Its redesigned 9" capacitive touchscreen improves visibility and navigation across routing, processing and effects management tasks, while 16 assignable SoftKeys and eight assignable Soft Rotaries provide flexible hands-on access to critical functions. Configurable chromatic channel meter LEDs further improve visual feedback in dark stage and theater environments. The expanded control surface layout makes the SQ7+ especially effective for larger worship productions, theater mixing, touring systems and professional live event environments where rapid access and workflow efficiency are essential.

Flexible Connectivity for Touring and Installed Systems

Built to integrate into large-scale professional audio systems, the SQ7+ includes 32 local XLR mic/line inputs, 16 XLR outputs, stereo line inputs, AES3 digital output and a 128x128 Intelligent SLink port for expansion with Allen & Heath stage boxes and networked audio systems. A built-in 32x32 USB-B audio interface supports multitrack recording and playback directly with Mac and PC systems at 48kHz or 96kHz, while SQ-Drive functionality enables stereo or multichannel playback and recording directly to USB media through the USB-A connection. The mixer also supports optional Dante, Waves, MADI and additional expansion card formats through its 64x64 option card slot, allowing the SQ7+ to scale into complex broadcast, installed and touring audio infrastructures as production requirements evolve. Remote network control through Allen & Heath control apps further expands operational flexibility for front-of-house, monitor and system management workflows.

Full-Scale SQ Control for Demanding Productions

Combining high-resolution FPGA processing, expanded onboard effects, scalable networking and the largest control surface in the SQ+ lineup, the SQ7+ is designed for demanding production environments where direct access, workflow speed and routing flexibility are critical. Its expanded fader layout and increased local connectivity provide engineers with immediate control over complex productions while preserving the streamlined operation and processing depth of the SQ platform. From touring systems and theater productions to houses of worship and large-scale live events, the Allen & Heath SQ7+ digital mixer delivers flagship SQ-series workflow and processing performance for professional live production environments.
