Allen & Heath SQ6+ RackUltra FX Enabled 48-Channel Digital Mixer

48-Channel Digital Mixer for Touring, Broadcast, and Professional Live Sound
The Allen & Heath AH-SQ6-PLUS is a professional 48-channel digital mixing console designed for live sound engineers, touring productions, houses of worship, broadcast facilities, recording studios, and corporate A/V environments that demand high-resolution audio quality with advanced workflow control. Building on the success of the original SQ6 platform, the SQ6+ introduces expanded processing power, RackUltra FX integration, a redesigned touchscreen workflow, and enhanced control capabilities for modern audio production environments. With powerful FPGA processing, extensive I/O flexibility, and premium onboard effects, the SQ6+ delivers professional mixing performance for demanding live and installed audio applications.

96kHz FPGA Audio Engine with Ultra-Low Latency Performance
At the core of the SQ6+ is Allen & Heath’s XCVI 96 kHz FPGA processing engine, capable of delivering professional-grade audio clarity with less than 0.7 milliseconds of latency. The system supports 48 input channels, 44 buses, advanced routing configurations, DEEP processing, multichannel recording, and extensive effects processing simultaneously without compromising audio performance. Full channel processing includes high-pass filters, parametric EQs, compressors, gates, inserts, graphic EQs, and advanced dynamics tools designed for precise live mixing and studio-level sound shaping.

Large Touchscreen Interface with Motorized Faders and Fast Workflow Control
The SQ6+ is designed for efficient operation in fast-moving live production environments. A responsive 9-inch capacitive touchscreen paired with Allen & Heath’s redesigned dark-mode GUI provides excellent visibility in venues, theaters, studios, and outdoor events. Twenty-five 100mm motorized faders, customizable SoftKeys, SoftRotaries, illuminated encoders, and drag-and-drop channel assignment allow engineers to build highly personalized workflows for front-of-house mixing, monitor control, livestream production, and broadcast applications. Integrated Chromatic channel metering offers clear visual feedback with detailed signal indication down to -72 dB.

RackUltra FX and DEEP Processing for Studio-Quality Mixing
The SQ6+ includes an extensive library of integrated effects and advanced processing tools suitable for both live and studio applications. Eight RackExtra FX engines provide dedicated stereo returns for reverbs, delays, modulation effects, and classic processing tools, while four RackUltra FX engines introduce premium vocal processing, advanced reverbs, saturation, pitch correction, and harmonic enhancement derived from Allen & Heath’s flagship dLive platform. DEEP processing support allows analog-style processing models to run directly inside channel strips and mix buses without introducing additional latency.

Expandable Connectivity for Touring Systems and Audio Networks
Designed for scalable professional audio systems, the SQ6+ features a 128x128 Intelligent SLink port for integration with Allen & Heath stage boxes, remote expanders, and additional consoles. Expansion card compatibility allows Dante, Waves, MADI, and additional SLink networking for broadcast systems, monitor splits, installed audio systems, and large-scale touring rigs. The integrated 32x32 USB audio interface supports multitrack recording, virtual soundcheck, livestreaming, playback, and DAW integration at both 96 kHz and 48 kHz sample rates.

Advanced Mixing Tools for Houses of Worship and Corporate A/V
The SQ6+ includes advanced Automatic Mic Mixing functionality that is especially valuable for conference rooms, educational facilities, panel discussions, broadcast productions, and houses of worship using multiple live microphones. Two independent 24-channel automatic microphone mixers can operate separately or combine into a single 48-channel system for larger applications. Remote control apps for Windows, macOS, iOS, and Android allow engineers and performers to manage monitor mixes, front-of-house sound, and venue-wide audio control from virtually anywhere.

Tour-Ready Construction with Integrated Recording and Remote Control
Built for demanding live environments, the SQ6+ features a rugged all-metal chassis engineered for touring, permanent installations, and mobile production setups. Integrated SQ-Drive functionality allows direct multitrack recording and playback to USB storage devices without requiring a separate computer or DAW. SQ MixPad and SQ4You apps provide wireless mixer control and personal monitor mixing for performers and engineers alike. With advanced audio processing, flexible networking, premium effects, and professional-grade construction, the Allen & Heath AH-SQ6-PLUS is built to handle high-pressure live sound and studio production environments with confidence.
