Ok, I have been researching how best to implement the BFD and have two conflicting sources. The SVS website says that when setting up the subwoofer that one should turn the amp all the way up and manipulate the sub signal via the receiver. The information on the BFD seems to say the BFD likes a hot signal and that it is best to turn the sub out signal as high as possible, but not high enought to clip the BFD, and then use the sub volume to produce the desired output level. So, what do we all think is the best advice? I guess the idea behind running the sub out hot is due to the possibility of the BFD not being very accurate for low signal strength, say if I am listening at -10 or -20 db from reference. If my typical listening level is -15 db from reference then do you think running the sub out hot is wise? I guess if someone would put together a start to finish installation of the BFD( I have seen what is out there but none of them are complete enough) that would help a bunch of people out. Thanks again.
