The new E Series Modules reproduce the legendary sonic signature of an early 80's classic, the SL 4000 E console channel strip, which was featured on countless 1980's recordings.

The E Series EQ Module features two different EQ's found on editions of the console produced between 1979 and 1987. Each EQ has unique response curves and tonal character. They are 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.
