Hello, I have a couple of questions for the forum. The first is I am noticing a hum noice in my center speaker when playing my blue-ray player. The second question is regarding speaker distance form receiver. I have an onkyo sr705. I did the calbration. The left front speaker is saying 12 foot but in reality it is only 6 foot. Is the calibration feet from the receiver or is it something else. All of the other speakers are off too. The third question is a quarter from zero, the subwoofer is making a hum. I have a 350V3. Any input would be greatly appreciated. Thank you.

Speaker distance is the distance from the main listening position to the speaker. Is that where you put the mic when you did the calibration?

If you have cable as your source of TV, and I suspect you might, the subwoofer hum *may* be a ground loop from your cable source ... make sure you have your TV cable well grounded. Regarding the Blu-Ray and the hum, I'd probably take a close look to make sure that particular series of cables has a tight connection on all inputs. Just a guess, so I could be and probably am way off base.
