The E12G was designed for the need for a high quality graphic equalizer in a 500 series module format. Its ease of use for sound shaping and frequency correction during tracking makes the E12G an indispensable tool in the studio. There are no IC chips in the frequency bands, as customary of other graphic eq designs. Instead of IC’s, the use of Class A preamps for each band was designed to keep your music from sounding “processed”, and help to bring out every detail of harmonic richness captured by the microphone and a high-end mic preamp. Additional frequencies 12kHz and 22kHz was chosen to fill a void in the high frequencies, not found in other graphic equalizers. The Ingenius® input stage, designed by Bill Whitlock of Jensen Transformers®, provides clarity and performance found in high end input transformers.
