can anyone pls explain the the value of Q in parametric equalizer? Yamaha suggests, lower the value of Q; wider is the bandwidth and viz a viz. Is there any formula to calculate it or just trying different values and judging the effect by gutt feeling is the only resort??? Being an engineer myself, I don't go on gutt feeling and need to know the exact thing. Any help is highly appreciated....

Unless specified like on the BFD, it is an arbitrary measurement. The BFD specifies the Q as 1/60 octave. Have you tried to contact Yamaha or ask in the Receiver section of the forum?

Filter Q refers to bandwidth – how wide an area the filter affects. Since you’re an engineer, here’s an on-line calculator. Since you mention “trying different values,” I assume you’re already using an equalizer. As you can see from the graphs at this post, functional bandwidth can vary from one to the next for a given value (i.e. how wide a path they cut). Regards, Wayne A. Pflughaupt
