And looking at the text regarding Q, they're contradicting what's shown in the graph and agreeing with what's been said here:

Quote:
"As the level of boost increases, you are not just boosting frequencies within the defined bandwidth. There will still be considerate boost outside the defined bandwidth, especially with lower "Q" settings."

But then they also add a sentence that says that the Q value doesn't remain constant while you fiddle with the boost knob on their amps - so the graph still makes sense for their implementation of the circuitry:

Quote:
"Please note that the "Q" setting marked on the amplifier is referenced to maximum boost. "Q" will drop in value as boost" [text is cut off there, I assume it should say "level is decreased." or something similar]
