The musical-sounding API 5500 Dual Equalizer embodies more than 40 years of tradition, beginning with the original 550 console equalizer module designed by Automated Processes Inc. founder Saul Walker. An industry first in the 1960's and the same as it ever was, the original 550's proportional Q filter design with reciprocal boost and cut is used.

API Audio's 5500 Dual Equalizer is a stereo equalizer which is essentially two API 550's within a single casing. This is an analog piece of gear that has XLR connections for both inputs and outputs, and also has a 1/4" input for each channel as well. It is rack mountable and will only take up a single space in a traditional rack casing.
