Hello Everyone, I am hoping for some coaching on how to use the FBQ 2496. Please disregard the second graph, I couldn't figure out how to remove it once I started the post.
The first graph shows what REW recommends for filtering and how the new curve will look. I've been reading Wayne's house curve information, but I wanted to try adjusting the BFD first to see if I can do the settings properly. I am inputting the measurements manually into the FBQ. The green lights on the FBQ are peaking on the third notch, so that could be part of the problem.
The measurement is for full-range speakers without a sub. Upon reading Wayne's write-ups on house curves and the manuals, I am unclear on how to set band-width properly on the FBQ. It appears that I need to set it on '1' (.167) for two of the settings and '2' (.20) on the middle peak. Though I think Wayne may have said it is better to set them for something close to a 1/24 octave -- I'm curious what bandwidth setting that is on the FBQ?
Also, should I be trying to increase the null at 56hz, or just leave it alone? I can't do anything about the suckout at 180hz because I have the FBQ only attached to the subwoofers on my speakers that cross over around 92hz.
I tried doing the settings and then ran another measurement. The curve was exactly the same, so I don't think I had the FBQ operating properly. The light on the PEG button is off (it seems it should only be on when making adjustments). Can someone please tell me how the FBQ should 'look' when it is operating?
Thank you in advance,
Nick
