Allen & Heath SQ6+ 48-Channel Digital Mixer

The Allen & Heath SQ6+ expands on the proven SQ platform with more hands-on control, advanced effects processing, flexible connectivity, and the same high-performance 96kHz XCVI FPGA engine that has made the SQ series a favorite for professional live sound applications.

Designed for venues, touring systems, houses of worship, production companies, and demanding live engineers, the SQ6+ combines 48 input processing channels, extensive routing, a large control surface, and powerful onboard processing in a compact and efficient digital console.

At the center of the workflow is a bright 9-inch capacitive touchscreen with a redesigned user interface, giving engineers fast access to channels, routing, processing, effects, and system functions. With 25 motorized faders, 16 programmable SoftKeys, and 4 assignable soft rotaries, the SQ6+ gives you significantly more physical control than smaller models in the SQ range.

Professional 96kHz XCVI Processing

The SQ6+ is powered by Allen & Heath’s advanced XCVI FPGA processing architecture, operating at 96kHz for exceptional clarity, low latency, and precise signal handling.

With up to 48 input processing channels, engineers have plenty of room for full bands, complex stage setups, multi-mic productions, and larger venue applications.

The console also supports Allen & Heath’s DEEP processing models, allowing premium-style compressors, preamps, and processing tools to be integrated directly into channels without requiring external hardware.

More Hands-On Control

The SQ6+ is designed for engineers who want fast access to more channels without constantly changing layers.

Its control surface includes:

• 25 motorized 100mm faders
• 16 customizable SoftKeys
• 4 assignable soft rotaries
• 9-inch capacitive touchscreen

This larger surface makes the SQ6+ especially well suited for live production environments where quick access to multiple mixes, channels, effects, and processing parameters is critical.

Expanded Effects Processing

The SQ6+ provides a powerful internal effects system with:

• 8 Multi-FX engines
• 4 RackUltra FX engines
• Support for DEEP processing
• Additional premium processing options through Allen & Heath expansion packs

The included RackUltra FX Essentials package provides professional effects such as:

• Spaces Reverb Vocal
• Spaces Reverb Instrument
• Plate Reverb Vocal
• Plate Reverb Instrument
• Saturation

Additional RackExtra and DEEP processing options further expand the console’s capabilities for vocals, instruments, live mixing, and system processing.

Flexible I/O and Expansion

The SQ6+ includes a generous amount of onboard connectivity and is designed to expand easily as your system grows.

Its 128-channel SLink port supports compatible Allen & Heath digital stage boxes and remote I/O systems, making it possible to build larger distributed audio systems.

The 64-channel I/O Port expansion slot also supports optional cards for professional audio networking systems such as Dante and Waves.

This makes the SQ6+ a strong choice for installations, touring rigs, recording systems, and networked audio environments.

32 x 32 USB Audio Interface

For recording and playback, the SQ6+ includes a built-in 32-in / 32-out USB audio interface.

This allows direct multitrack recording to a Mac or PC without requiring a separate audio interface.

The console also features SQ-Drive, allowing multichannel audio recording and playback directly through compatible USB storage devices.

Whether you're capturing a live performance, running virtual soundcheck, or recording rehearsals, the SQ6+ provides a highly flexible recording workflow.

Automatic Mic Mixing

The SQ6+ includes Automatic Mic Mixing for up to 48 channels, making it especially useful for:

• Conferences
• Panel discussions
• Corporate events
• Houses of worship
• Presentations
• Speech-heavy productions

Automatic mixing helps manage multiple open microphones while improving clarity and reducing unwanted buildup.

Plenty of Power for Complex Productions

The Allen & Heath SQ6+ is built to handle demanding live sound applications with a generous combination of onboard I/O, flexible routing, and an expanded hands-on control surface.

With 24 local mic/line inputs, 48 input processing channels, 12 mixes, and 6 matrices, the SQ6+ gives engineers plenty of room for full bands, multi-mic productions, larger venues, houses of worship, and touring systems.

The surface features 25 motorized 100mm faders, 16 programmable SoftKeys, and 4 assignable soft rotaries with LCD displays, giving you fast access to important functions without slowing down your workflow.

For connectivity, the SQ6+ includes 24 XLR mic/line inputs, stereo line inputs, multiple analog outputs, AES digital output, and dedicated talkback connectivity. Its 128-channel SLink port and 64-channel I/O expansion slot allow the mixer to grow with larger systems, digital stage boxes, Dante networks, Waves systems, and other professional audio workflows.

Whether you're running a club, church, touring rig, corporate production, or permanent venue installation, the SQ6+ provides the processing power and expandability needed for sophisticated live sound systems.

Allen & Heath SQ6+ Specifications

Expandable I/O for Growing Systems

One of the biggest advantages of the SQ6+ is its ability to expand well beyond the console itself. The built-in 128-channel SLink connection supports compatible Allen & Heath stage boxes and remote I/O systems, allowing your inputs and outputs to be positioned directly on stage.

The dedicated 64-channel I/O option slot provides even more flexibility with optional network cards, making the SQ6+ easy to integrate into Dante, Waves, recording, broadcast, and larger installed audio systems.

Designed for Fast Live Mixing

The larger SQ6+ control surface gives engineers more immediate access to their mix compared with smaller consoles. With 25 motorized faders, extensive customizable controls, and a large touchscreen, important channels and functions stay within easy reach.

That combination makes the SQ6+ especially well suited for live bands, clubs, theaters, churches, corporate events, touring productions, and professional AV installations where speed and control matter.
