Reproduce the legendary sonic signature of an early 80's classic

The E-Series EQ Module for 500 Series racks reproduces the legendary sonic signature of an early 80's classic, the Solid State Logic SL 4000 E console channel strip, which has featured on countless classic recordings from the 1980's to the present. The E-Series EQ Module features two different EQ's 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' EQ's. 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. The 'Brown' EQ, featured on the discontinued SSL E-Signature Channel Strip, is now uniquely available on the E-Series EQ Module.

If I was outfitting a console with 500-series EQs, and budget was not an issue, I would choose the 611EQ as my primary EQ, as it can pretty much handle anything you throw at it. Maybe that's one of the reasons why SSL desks are always in high demand. - Tape Op Magazine 2017
