[QUOTE="John Roberts, post: 97211, member: 126"] Re: Death to... test what you think you know In the interest of completeness it may be worth inspecting how "most" GEQ are designed. They first create individual bandpass filters for each GEQ center frequency then add or subtract that BP signal to the dry path to create boost or cut. These are pretty much a blunt instrument, a dull knife so to speak, with different topology/design philosophy variations. How adjacent bands combine and interact with each other will vary with different circuit topologies and different design trade-offs. (insert my tired Q definition rant here). A smart digital GEQ could be taught to interpret adjacent "death to" slider settings differently, but conventional GEQs will give conventionally poor combined results. Adding deep GEQ cut near a critical crossover pole is asking for trouble as crossovers are not just about amplitude but phase response in the critical transition region. JR [/QUOTE]
