The MinEq is a 2hp simple 3 Band Equalizer Eurorack Module.

This hybrid Baxandall circuit provides +/- 20dB~ of boost or cut control over the Low, Mid and High frequency bands of an audio input. The circuit is capable of up to 20vpp~ of boost(with a 10vpp signal) and attenuation down to 1-2vpp depending on the input. The frequency bands are centered near 30Hz(Low), 1kHz(Mid), and 10kHz(High). The circuit is AC coupled and will invert the input. With all the potentiometers at noon, the MinEq passes the signal relatively unaltered.

The graph of frequency response curves are from the National Semiconductor Handbook are an approximation of how the circuit will work exactly.
