500 Series 2-band EQ, 25 peak and 12 shelf settings, stepped gain +/-6dB, vintage-style inductors, stereo matchable, solid-state, single-slot module
The Electrodyne 511b is a modern expansion of a classic, bringing the legendary sound of the original 511 and vintage 711L equalizers into a 500 Series format with significantly extended flexibility. Using the same custom inductors, opamps, and transformers as its predecessors-still crafted by the original manufacturer-the 511b delivers unmatched tonal smoothness and musicality across the entire gain range.
With 12 shelving and peaking frequencies per band and switchable wide/narrow Q options, the 511b provides a total of 37 precise EQ settings. Each band offers six peaking and six shelving frequencies, with stepped-gain controls in 1 dB increments for exact adjustments, ideal for both tracking and mastering. Whether you're sculpting individual sources or dialing in a stereo pair, the 511b maintains consistency and warmth with a design that honors its roots while meeting today's demands.
