...It is a TWO channel eq right ? ..can you eq one sub on one channel and then eq another sub with a different set of parameters on the other channel and use them both at once ?. One channel will be getting an lfe signal and the other channel will be getting everything from 80 hz and down from the main l/r channel. Im wanting to eq my main l/r speaker's woofer's (wired in paralell as one speaker) on one channel of the bfd and then the lfe sub (svs) on the other channel of the bfd...I was gonna get two bfd's but thought maybe I could do it all from one bfd.Any help would be apreciated. Do I need one or two bfd's?
