    Channel calibration

    I'm using RadioShack Analog-Display Sound Level Meter (model 3302050) to calibrate channel levels on a Rotel RSP-1066/RMB-1075 combo, together with "Avia: Guide to Home Theater" DVD. However I get different results if I use the samples within the AVIA DVD when compared with the build in test tones of RSP-1066. Question is, what samples of pink noise should I use, the ones from RSP-1066 or the one from AVIA DVD? What are the differences in both methods?

    I´m using a calibrationdisc.
    Cause I believe that it will be more correct.

      Personally, I use the S&V calibration DVD. But realistically speaking here, the calibration tests are just that, a calibration test of each speaker in reference to other speakers. SO in theory it doesn't make a difference which source you use because ultimately you'll still end up with the same "speaker level compensation". The true difference is at what volume do you need to set your AVR to get your "reference" sound level. The calibration DVD will be much louder than the internal pink noise generator so thus, you could have your 75 db reference point at a lower volume setting on your AVR then the internal pink noise generator.

        Pbarta,

        By getting different results, do you mean the relative levels between the speakers are different or your getting absolute SPL levels on the meter? If you are getting relative differences between the speakers, I'm not really sure whats going on. On the other hand, if your getting an absolute difference as to the position of the volume to reach 75 dB, you are probably seeing a difference between the Avia recorded signal level and the Rotel test tone signal level.

        FWIW...I use Avia.
