[QUOTE="Michael John, post: 4870, member: 830"] Hi, I've been looking over 3-way DSP presets for some high end touring products and occasionally I notice odd out-of-band filters. For example in one preset, the mid range channel has a narrow boost of about 6 dB at a frequency that's at least 1 octave lower than the low-mid crossover frequency and where its high-pass filter is at least 20 dB down. (I could understand a cut, to reduce a resonance, but not a boost.) Can anyone explain why there might be narrow out-of-band parametric filters? Boost or cut. Cheers, Michael [/QUOTE]
