Just got my BFD for $134 shipped from www.lentines.com (a B&M music store in Cleveland). I'm trying to tame a 50 Hz peak. I also understand (from Wayne?) that I should gradually bump up as I approach 20 Hz. I'm working with a Yammy 2092 and an SVS 25-31PC. Hookup was a breeze, with RCA cables and Radio Shack (part 274-884) monaural 1/4" jack adapter (phono plug to 1/4" phone jack, gold plated). I also used a cheater plug on the power cord so I didn't have to worry about ground induced hum. People have spoken about the complexity of dialing in this parametric equalizer. I agree it is tricky but I think within the capabilities of any of the subscribers to the HTF. As I see it, the whole key is understanding that only the frequency setting actually displays a frequency. The bandwidth and fine buttons really are in 1/60 of an octive. The fine button moves you up or down in from the preset frequencies stored in the frequency button. I think the biggest confusion is that the numbers for fine and bandwidth aren't in HZ but in 1/60 octave. For example, if I set the frequency button to it's preset of 40 HZ, if the fine button reads +6, it means my frequency is really centered at 43 Hz. In order to know this, you must follow BFD's chart in their manual. If I want the bandwidth around 43 to be from 41 to 45, I would set it to 8; which is really 8/60 octave. Again, you must use the BFD chart to determine this. My point is that once you understand the above (and it's easier to understand once you're doing it on the BFD) the whole thing falls into place. Another tip is when you're storing your changes, you press the store button twice. One press starts the preset number flashing; you must press store again to really save it. This second store must be pressed while the preset number is still flashing. Hope this helps, I'm waiting for my Stryke CD101 (www.stryke.com) to come in so I can really dial this puppy in.
