Allen & Heath SQ-5

16 Onboard Preamps / 12 Stereo Mixes + LR

Allen & Heath

Product Highlights

  • SQ features 8 stereo FX engines and the acclaimed RackExtra library, which includes emulations of legendary classic reverbs, gated reverbs, delays, modulators, and more. Each engine has its own dedicated stereo return, you won’t have to use any of your 48 input channels.
  • SQ includes all the processing you’ll need to create the perfect mix. Each input has an HPF, a super-fast gate with sidechain and filter, a musical 4-band parametric equalizer, and a Peak/RMS compressor for level and transient control and shaping.
  • Mixes include a parametric and 28-band graphic EQ, as well as a compressor, all of which are ready to use when needed.
  • Expandable to 48 Input Channels.
