In Reply to: Re: SPL Readings for HT posted by kotches on February 02, 2002 at 17:14:35:
That makes sense. Originally, what I did was to set all speakers to 0.0 dB within the individual settings for each. Set the meter up, and moved each individual setting up or down as needed until I leveled off at 74dB on the SPL meter (each speaker is within +/- .5 dBof each other). That is accept for the sub which, even with meter set on slow, bounces around between 73 - 75dB (average around 74.3). (I do have a little weaker bass response on the far left side of my viewing area so run the bass little higher).I normally watch movies at -15 dB on my Ref 30 and I would assume, based on what you said, that if I ran the Video Essentials or Avia disks at 0.0 dB on my Ref 30 the readings on my SPL meter would probably approximate what I have already found. That is why, when I run these disks at a normal listing level the test tones seem soft. Thanks for your response. Any other info would be welcomed.

KM,Correctly set for reference level, you need to set to 75dB ;-) I think 74 will work just fine!
AVIA is recorded at -20dBFS (20dB below full scale signal) so 85dB with volume at 0.0dB is what you should get. VE is recorded at -30dBFS so 75dB is what you should get. The LFE channel has 10dB extra on it. Both discs account for this and attenuate by 10dB so that the subwoofer ends up at the same level as the other speakers.
Assuming you're using the Radio Shack SPL meter, you should calibrate the subwoofer 2 to 3 dB below the other speakers, as this meter is inaccurate at both frequency exteremes.
Regards,
I use the Ref 30, it's a good pre/pro.
