Tired of working completely in the box? Add a 500 series EQ to your recording studio and get the analog warmth we all love with modules such as the API 550a, MAAG Audio EQ4, or Pultec EQP 500A. 500 series modules offer every style of EQ from classic parametric, to precise graphic EQ. Most often they will include a high and low pass filter, multiple frequency bands, side chain options, or added line input gain staging to oversaturate you signal for pleasant harmonic distortion.

Don’t let the size fool you, 500 series EQ modules are just as powerful as their larger counterparts, just packed into a convenient smaller package. They are a great way to add overall EQ to your mix bus, attack to your drums, depth to synths, and attitude to bass and guitars. Easily use them as subtle enhancements, or crush the original signal to create a completely unique sound. Contact your sales engineer to find out what the best 500 series EQ works best for you.
