Solid State Logic E-Series EQ Module

Loved by Generations of Professional Producers

The SSL E-Series EQ Module 500 series reproduces the legendary sonic signature of an early 80’s classic, the equalizer section of the Solid State Logic SL 4000 E console channel strip, which has featured on countless classic recordings from the 1980s to the present and shows no sign of stopping. The 611 design E-Series EQ also features on Solid State Logic’s latest audio production console, ORIGIN.


  • Immortal SSL 4000 E Series circuitry
  • “Black-242” and “Brown-02” twin EQ design
  • Versatile 4 band channel EQ
  • Bell curve option on HF and LF
  • Fully parametric LMF and HMF with Q
  • Based on the classic 611E console channel strip

Unique response & tonal character

The E-Series EQ Module features two different EQs found on editions of the console produced between 1981 and 1989. Each EQ has unique response curves and tonal character. Historically the type of EQ fitted in an individual console was distinguished by the colors used on the LF knob caps so the two flavors have become known as the ‘Brown’ and ‘Black’ EQs. On the E Series EQ Module, you can switch between these two different flavors of EQ that have been loved by generations of professional producers.
