Re: sub hums if I turn on SPL meter

I don't understand why the BFD is already necesairy to be connected between the receiver and the sub if all frequenties in the BFD are still set at 0.0db so they won't change anything in the signal.
I'm confused about why you are concerned about this. What are you proposing and why?

I set the level of my receiver so that my spl needle indicated 75db but on the VU meter in REW it only reads 40db.
Sounds like the SPL meter is not connected properly to the line-in of the soundcard. You're not getting a signal from the SPL meter into REW through the soundcard input. Does the SPL meter and cable function properly - you can test the meter and its cable by plugging it into the receiver (AUX input) and test it like any other microphone....
