Axiom Home Page Forums General Discussion Technical Questions Test tones - which ones to believe?

Hello everyone,

I recently purchased a SPL meter. I have calibrated with the Yammy's built-in test tones, as well as the Yammy DVD-A/SACD player tones.

In order to get the right balance between the receiver and DVD-A player, I had to drop the receiver's sub output level to the lowest setting (-20db), and crank the DVD-A player's sub level to max (+6db)...and then set the volume on the sub. So far, all is not too bad...sub output is about 1-2db above reference.

When I play the test tones on the S&V Home Theatre Setup, the sub tones are waayyyy off the scale.

Has anyone encountered the same issues? Which test tones should I believe?
