Why the Allen & Heath SQ-6 Is a Smart Choice for Your Venue

If you're outfitting a live music venue, a KTV club, a house of worship, or a touring rig, the Allen & Heath SQ-6 is one of the most rider-friendly digital mixers on the market. It packs a 96kHz FPGA core, 48 input channels, and a 12-inch touchscreen into a compact, road-ready chassis. Buying a used Allen & Heath SQ-6 from Acoustrade gives you that same professional performance at a fraction of the new price.

At Acoustrade, we specialize in tested, second-hand pro-audio gear. Every SQ-6 we sell is inspected, cleaned, and functionally tested by our technicians before it ships. You get reliable gear without the new-box markup.
