H-EQ Hybrid Equalizer.

H-EQ is a seven-band equaliser where each band can take a different console character, chosen from seven models covering US and UK vintage, US and UK modern, and two digital designs. That per-band choice is the reason to use it, since a low shelf and a presence lift rarely want the same circuit. Five bands are fully parametric, high and low pass have selectable slopes, and it processes left and right or mid and sides independently.
