Solid State Logic 500 Series 611 EQ Module

Legendary SSL sound quality and vibe

Since the early ’80s, producers, engineers, and artists have revered SSL E Series consoles for their huge sound and distinctive character. A big part of the sound came from the E Series channel strip, and you get the same circuits in the 611EQ module.

“Brown Knob” EQ: the original SSL EQ, sweet and musical

Early SSL E Series consoles sported the “Brown Knob” EQ design (named for the color used on the LF section’s knobs). You get 15dB of cut/boost, and a special design that ensures the 3dB up/down points for each band fall at the same musical interval from the center frequency. Said another way, no matter where you cut or boost the 611EQ, the results sound natural and highly musical.

“Black Knob” EQ: a more aggressive EQ for modern styles

In the mid-’80s, SSL worked with the legendary George Martin to develop the 242 EQ circuit, or the “Black Knob” EQ to be found on later E Series consoles. It’s more aggressive than the “Brown Knob” EQ, with up to 18dB of cut or boost, and a different control circuit layout that gives you much tighter reign over low frequencies.
