Although Calrec no longer manufactures analog audio gear, their older Polar consoles featuring the 1549 4-band parametric EQ remain legendary. The circuit has since become a favorite among DIYers, and now it is available as a kit for the 500-series from DBDawg Audio.

CEQ Features:

  • Wima capacitors, metal film resistors
  • Bournes potentiometers
  • relay-controlled Q, shelving, and bypass
  • 4-band parametric, bell/shelf switch on high and low band


  • $375 for full kit
  • $165 for partial kit (contains only PCB, faceplate, pots/knobs)
  • $580 for assembled/tested
