Question on proper volume levels for testing


I apologize if this has been asked, but I searched all over and I appear to be the only dumb one with this question:

My sub is connected to my BFD, which is connected to my receiver. When I use REW, I connect the soundcard to the BFD, and remove the connection to the recevier (unless I'm mistaken already). When I do the setup for the REW, i.e. levels, calibration, etc., how high should the volume knob be on my sub?

Or am I missing the point? Should it be set to whatever it needs to be so that the Radio Shack meter reads 75db?

Assuming then that I finally manage to EQ the sub (if I can get the above questions resolved), when I go to re-integrate it with the rest of my system, which device do I plug the external sound card into at this point to run a sweep to say 200hz (or higher?) to see how the sub matches with the other speakers (I'm guessing the receiver at this point)? And what volume level should I run these tests at?

I feel like I may be making a lot out of a nothing issue, but for some reason I'm having a mental block on these items. Thank you in advance for any advice.

Re: Question on proper volume levels for testing


Hi there,

The sound card should go into the receiver's analog inputs. So it goes like this:

Soundcard->Receiver->BFD->Sub

I'd suggest starting with the sub volume somewhere in the middle, and then adjusting the receiver volume till you get 75 dB. Then go from there.

Good luck

I'm an idiot, completely overlooked that drawing even though I saw it previously.
