Re: Parametric eq with only two opamp sections
FYI - The Q-range on that Crest EQ is 0.7 to 3.0

Re: Parametric eq with only two opamp sections
Here's a SIM I did on this some years back on the Crest Century V12 which has variable Q in this topology:
Looks to me like Q and gain are not interacting too much.
Here's the schematic (also a JP design):

Parametric eq with only two opamp sections
Hello, Just registered on this forum and thought I should make a small contribution - perhaps it will be of interest to some of you. Parametric eq's (with independently variable centre frequency, bandwidth/Q and cut/boost) are by large created using a state-variable filter consisting of to integrato...
