What the Allen & Heath SQ-6 Is

The Allen & Heath SQ-6 is a 48-channel digital mixing console from the British manufacturer's SQ series. It sits in the mid-size range of the lineup, with 24 onboard mic preamps, a 12-inch touchscreen and motorized faders, aimed at live sound, houses of worship, touring and fixed installations.

The name is often typed as "allen heat sq6" — the correct spelling is Allen & Heath SQ-6. It is the same product; the search term is simply a common misspelling.

The SQ-6 is built around Allen & Heath's XCVI 96kHz FPGA core, which is the processing engine behind the series. That 96kHz operation and low-latency design are the main technical selling points compared with older 48kHz consoles in a similar price bracket.

Key Features at a Glance

  • 48 input channels with 24 local mic/line preamps
  • 96kHz XCVI FPGA processing core
  • 12-inch capacitive touchscreen plus a physical control surface with motorized faders
  • Built-in SQ-Drive for multitrack recording and playback to USB
  • Dante, Waves and other option cards via the SQ option card slot
  • Scene and show memory for repeatable setups
  • App control for remote mixing from a tablet
  • Compact footprint relative to channel count, which suits smaller venues and mobile rigs

Exact I/O counts and expansion options should always be confirmed against the current Allen & Heath datasheet, since firmware and hardware revisions can differ.

Who the SQ-6 Suits

Live music venues and clubs

The SQ-6 handles typical band setups — drums, bass, guitars, keys and several vocal mics — without needing an external stage box for many small-to-mid rooms. Its scene memory makes it practical to recall settings between different acts on the same night.

Houses of worship and corporate AV

Fixed installs value the touchscreen workflow and the ability to lock down scenes for volunteer operators. Remote app control lets a technician walk the room during soundcheck.

Rental companies and integrators

The SQ series is widely used, so rental inventory and operator familiarity are strong. For integrators, it is a common spec item in mid-size venue projects.

Studios and content production

SQ-Drive recording and the option card slot make the SQ-6 usable for multitrack capture, though it is primarily a live console rather than a dedicated studio desk.

Buying a Used Allen & Heath SQ-6

A tested used SQ-6 is a sensible way to get 96kHz processing at a lower cost than new. When evaluating a second-hand unit, check the following:

  • Fader condition — motorized faders are a wear item; confirm they move smoothly and hold position.
  • Touchscreen responsiveness — check for dead spots or delamination.
  • All mic preamps — test every input for noise, gain and phantom power.
  • Firmware version — confirm it is current or updatable, and that the unit is not locked.
  • Option card slot — verify the slot works if you plan to add Dante or other cards.
  • Power supply and fan — listen for unusual noise and confirm stable boot.
  • Physical condition — knocks around the connectors and screen bezel are common on touring units.

Buying from a supplier that tests and documents condition is safer than an untested private sale. Acoustrade supplies tested used pro-audio equipment, including digital mixers, alongside amplifiers, speakers, line arrays and microphones, so a full venue system can be sourced together.

SQ-6 vs Other Options

Within the SQ family, the SQ-5 offers fewer channels and a smaller surface, while the SQ-7 adds more faders and I/O. If you need more inputs than the SQ-6 provides, an expansion stage box or a larger console may be the better fit.

Compared with older analog desks, the SQ-6 brings scene recall, built-in recording and app control. Compared with entry-level digital mixers, it offers higher sample rate processing and a more capable control surface.

FAQ

Is "allen heat sq6" the same as Allen & Heath SQ-6?

Yes. "Allen heat" is a common misspelling of Allen & Heath. The product is the Allen & Heath SQ-6 digital mixer.

How many channels does the SQ-6 have?

The SQ-6 provides 48 input channels with 24 local mic preamps. Confirm exact I/O against the official datasheet for your firmware version.

Can the SQ-6 record multitrack audio?

Yes. It includes SQ-Drive for recording and playback to USB, and the option card slot supports expansion cards for additional connectivity.

Is a used SQ-6 a good buy?

A tested used unit can be good value, provided faders, preamps, screen and firmware are verified. Buy from a supplier that tests equipment and documents its condition.

Does the SQ-6 work for fixed installations?

Yes. Scene memory, app control and a compact footprint make it a common choice for worship venues, clubs and corporate AV rooms.
