Authentically reproducing the sonic signature of an early 80's icon, the SSL E-Series EQ 500 Series Module captures the equalizer section of the SSL 4000 E console channel strip, a unit featured on countless hit recordings from the 1980's to today, and beyond. Features 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 classic 611E console channel strip Featuring two different EQs found on editions of the SSL 4000 E console built between 1981 and 1989. Each EQ has unique curves and tonal footprint. Traditionally, the type of EQ in a console was distinguished by the colours used on the LF knob, so the flavours have become known as the 'Brown' and 'Black' EQs. On the E Series EQ 500 Series Module, you can switch between those two different characters of EQ, granting you access to the flavours adored by generations of producers and engineers.
