ok, this may be a Jakeman question, but I noticed something that makes no sense. I have my subs daisy chained togethor, so I have receiver to 350(1) to 350(2) to 600. I've tried using seperate coax lines to them but I get the same results with the spl meter, so looks like daisy chaining is ok. ?
Anyway, I noticed something weird tonight. I'm using the SMS-1 to just plot my graph right now, I am not running any of the subs throught it, just using the mic to see what happens as I move mysubs around, etc.
Anyway, I have a very high hump around 40hz or so, so I was trying to move my 600 around, wewwww, to see if that helped. So then I turned off the power to the 600 and the graph didn't change much, other than the slope fell off sooner in the lowww hz.
Then I unplugged my line in cable to the 600 and my graph from 25-40hz pegged at the top range of the SMS-1 graph. Plugging the cable back into the Line In on the 600 dropped the graph as I was seeing before.
If the sub is turned off and all I am doing is unplugging/plugging in the line in cable, how can the change the graph unless there is some type of feedback going back to the 350's in the chain?
