Allen & Heath SQ5 Plus Digital Mixer

The SQ-5 already had a loyal following before Allen & Heath decided to give it a glow-up. The SQ5 Plus keeps everything that made the original a go-to for owner-operators, mid-sized venues, and small tours — then throws in more processing power, a crisp 9" capacitive touchscreen, and a redesigned GUI that actually makes sense to use.

Crystal-Clear 96 kHz Processing

Some mixers claim "pristine audio" and deliver something closer to AM radio static. The SQ5 Plus is not one of those mixers. Under the hood, the 96 kHz XCVI core processes 48 input channels with ultra-low latency and phase-coherent mixing — which is just a fancy way of saying your audio will sound clean, tight, and honest. Plus, with direct DEEP processing, you get classic studio preamps and compressors built right into the system with zero added latency, saving you from laggy external plugins.

96 kHz XCVI Core & DEEP Processing: Run premium analog emulations directly on the core, earning nods of approval from even the most cynical sound engineers.
8 FX Engines with RackUltra: Four dedicated RackUltra FX engines join four standard engines, giving you a sonic arsenal that will make your reverb-loving guitarists very happy.
Comprehensive Bus Routing: Rigid signal paths are for people who like rules. Route your signals wherever you need them with total flexibility.

An Intuitive Surface

Nobody got into live sound because they love menu-diving like a digital archaeologist. The SQ5 Plus rescues you from sub-menu purgatory with a gorgeous 9" touchscreen and an intuitive GUI that puts the right controls exactly where your fingers expect them. Combined with 17 motorized faders, it’s as satisfying to use as it is easy on the eyes under stage lights.

9" Touchscreen & Reimagined GUI: Navigate 48 channels without feeling like you're trying to defuse a bomb in the dark.
17 Motorized 100mm Faders: Customize your layout to match how your brain actually works, rather than how a designer in 2009 thought it should.
Carbon-on-Graphite Finish: Refined controls and updated artwork give this mixer a premium look that says, "Yes, I absolutely know what I'm doing."

Allen & Heath SQ5 Plus Connectivity & Control

Connectivity & Control That Goes the Distance

An audio console is only as good as its connections, and the SQ5 Plus has plenty of them. From traditional XLR analog inputs to a 128x128 SLink port and a built-in USB interface, it fits seamlessly into your workflow. It's also fully network-ready, so you can tweak the mix from an iPad at the bar — or from the parking lot, if the band decides to play that song again.

128x128 SLink Expansion Port: Massive system integration options so your setup can grow without requiring you to buy a whole new console.
Built-In 32x32 USB Audio Interface: Record multichannel audio straight to your DAW, making your laptop an official part of the rig.
Network-Ready with Remote Apps: Control the mix on iOS or Android devices, giving you the freedom to step away from the desk and actually hear the room.

The Mixer That Does the Heavy Lifting

The Allen & Heath SQ5 Plus is the console that quietly becomes the backbone of your setup — like a great stage manager, you only miss it when it's gone. It delivers 96 kHz audio quality, serious processing headroom, an intuitive surface, and connectivity built for real-world demands. If you're after a digital mixer that punches above its weight, this one deserves a closer look.
