Hi,

Is there a simple way to translate the db/octave filters I used with a DCX2496 to the Q used in the MiniDSP.

In other words, what is 6dB Octave and 12 db Octave in Q?

Thanks

Hi Steve - I'm not much familiar with the DCX, but in the miniDSP the crossover filters are 6dB, 12dB, etc. Q applies to the parametric eqs. Is this for a low/high-shelf filter?

As already answered by John, I think that you're mixing up two things here... db/oct would be for a filter (e.g. LPF/HPF) in the central part. It's showing as such in the DCX I would believe.. The Q setting is there but embedded in the "Type" of LPF/HPF i.e. Butterworth or Linkwitz Riley. But I really doubt that DCX uses different convention on these...

As for the Q on the Parametric EQ, that's a standard setting that you can copy and paste between the DCX PEQ settings to your miniDSP.

Hoping this clarifies... have a google online for more information about filters if this is still confusing.

Sorry, I wasn't very clear.

It is shelving filters I am referring to.

The DCX has either 6dB or 12dB shelving filters which I would like to match with the minidsp. What should the Q value be?

And, as a feature request, could you have the ability to select the slope of shelving filters in dB/Octave rather than Q factor?

Empirically (just having a look at the plugin) it appears to be 1 and 2. I couldn't explain why exactly though...

maybe first order and second order?


I dont see how these correlate though. "Q" is a measure of bandwidth. for a PEQ, if you have a center set at 500hz and Q of one, then it will effect everything for 1 octave up and down. Q of 2 and two octaves. db/oct is a rate. it specifies how steep a slope is and has nothing to do with bandwidth.
