Behringer BFD Feedback Destroyer Pro DSP1100p Parametric EQ If you're looking at this, you know what it is. Great for equalizing room induced peaks out of a subwoofer's response. http://www.behringer.com/02_products...1100P&lang=eng 24 bit internal processing, 20 bit AD and DA converters. 2 channels, 12 filters each. (Can use this to eq a stereo sub setup too.) Includes a copy of the manual. (I have the original around here somewhere, but if I can't find, I'll download a copy from their web site.) Buyer pays shipping. Cashier’s check, money order, personal check (must clear 1st), and Paypal accepted. My ebay id is kcb-5. Check it out: NO NEGATIVE FEEDBACK. Ever. Zip, zilch, zero negative comments from anyone who has dealt with me. I'm not a dealer out to make a buck. Just an audio/videophile who likes to try different things. I'm looking to get $60 for it. If you check ebay and other places, that is a very reasonable price. Cheers!
