Q values for equalizer. How does it measure?

(1/2) > >>

gorman:
I read the manual and I understand that a smaller value affects a narrower set of frequencies but... on what unit of measure?

Llorean:
Q is a specific term relating to equalizers. As far as I know, "Q" actually is the unit of measure (more or less) and the range it covers depends on the frequency it's centered around. That being said, I don't use it often, and more detailed information would probably best be sought with Google, as it is a more or less standard term.

Ooops, I didn't know this. I was used to the Rio Karma parametric equalizer that used a different terminology. It would be nice to fill in details in the manual about this, as it's pretty mysterious to uninitiated.

I know, I was thinking this while I typed the previous message. If I'll manage to wrap my head around this I'll try to contribute.

Thanks a lot for the help.
