Q107 State Variable VCF - "Constant Bandwidth"?

Author Q107 State Variable VCF - "Constant Bandwidth"?

I saw this many moons back, never thought to ask the forum about it.

"Constant Bandwidth" label on a "SWSPDT" header on the PCB.

"SWSPDT" - ok I get that part, it's a header for a SPDT switch.

But what is "constant bandwidth" and why would I want it?

Here's a screen grab from the Q107 datasheet:



Thank you.

AH! Now that makes sense! I remember learning about that set of issues back when I was selecting graphic EQs for my bass guitar setup a few years ago.

I suppose there's no reason I can't just try it out on the Q107 then. I mean, Roger put it there for some reason, right?

Thanks for chasing that information down.
