Buying a Used Allen & Heath SQ-6

When shopping for a used SQ-6, consider these points:

  • Firmware and feature licenses: Check that the unit has the latest firmware and any DEEP processing licenses you need. Some licenses are tied to the console.
  • Physical condition: Inspect faders, encoders, touchscreen, and connectors for wear. Motorized faders can be a wear item.
