Digital Mixer

Allen & Heath SQ-5 Digital Mixer

The Allen & Heath SQ-5 is a professional-grade digital mixer with 48 channels, 36 buses, and an intuitive touchscreen interface that handles complex IEM mixing workflows with ease. Its SLink digital audio bus supports up to 128 channels of I/O expansion via remote stage boxes, and built-in DEEP processing provides high-quality dynamics and effects. While it requires a shelf to rack-mount, its processing power and sound quality put it a tier above budget rack mixers.

01 · What it does—and what that changes in your rig.

Product overview

Start with the payoff, then work through how it functions, where it fits, and the details that change a real build.

The payoff

Digital Mixer decisions, organized around the whole rig.

The SQ-5 is the small-format console that refuses to mix like one: 48 channels and 36 buses on a 96kHz FPGA engine, with latency low enough that stacking it in an IEM chain doesn't smear the timing performers feel through their ears. For worship rooms and self-mixing bands it hits the middle of the Venn diagram — professional bus architecture, a touchscreen workflow volunteers can learn, and a footprint one person carries.

Function

How it works in the path

The SLink port is the rig-design centerpiece: 64 channels each way over one Cat5e to A&H's stage boxes and expanders, which is how the console's onboard preamps grow into a full stage without a snake trunk. The same ecosystem feeds ME-series personal mixers downstream, and the USB-B port records 32×32 for virtual soundcheck. It's a surface console rather than a rack brain — plan a case and a doghouse, not rack rails — with the 80–100W draw and the mix position real estate that implies.

Best fit

Where it earns its place in the system

Comparison shoppers land here between an X32-family rig and a dLive budget: the SQ sits deliberately between them — cleaner engine and ecosystem than the former, a fraction of the latter's price, with deep-show automation as the main thing you'd still be missing.

Details worth deciding before load-in.

  • One SLink run to a stage expander carries the whole stage — keep the spare Cat5e rule here too.
  • Feed ME-500/ME-1 personal mixers from the same ecosystem for a one-vendor monitor path.
  • Virtual soundcheck over USB-B is the volunteer-training superpower — record Sunday, rehearse Tuesday.

03 · What this product asks of the rest of the system.

Compatibility

Treat connector names as the start of the check—not the answer. These are the boundaries that determine a complete working path.

Best fit · Digital Mixer

Use it as digital mixer tracked outside rack rails; follow the manufacturer’s mounting and form-factor guidance.

Plan the companion path

Complete the path with upstream and downstream gear that matches connector, direction, signal type, protocol, and wiring standard.

Protocol boundary

This product declares SLINK; matching plugs alone do not make other protocols compatible.
