    Get my anologue SPL meter in the post this morning, set it all up to calibrate my 3802, start the tones. All my previous 'done by ear' settings were dead on 75dB @ 00!


    The method I used to do it by ear was;

    Listen to 2ch CD
    Adjust front levels so image appears central
    enable 4ch stereo (i have no center) adjust rears so image remains central
    Match front right to rear right by ear.


    Lucky that I got them all to 75dB but they were all equal.

    I'm not that talented. I just got one this week and, to me, it was amazing how far I was off.

    How do you adjust the front levels? On my Sony 5ES, I can only adjust the center and surround levels.

    I can get to within 2 or 3 dB adjusting by ear, but I got the meter anyway, since I want it to be perfect [​IMG]

    It is useful for more than just that.

    You can also measure a speaker's frequency response graph with an SPL meter and a Cd that has a broad range of test tones such as the Sterophile Test Cd's. Ste your volume the go through each test tone and mark its dB level on a graph once done with all test tones connect the dots and you have it.

    Anyone know how accurate the HK EZSet remote is? It adjusted my center and right front to +10(which happen to both be off to the right due to room location). It seems weird since they seem closer than my left front which was set to +5.

    I like to calibrate then "fine tune" by ear, especially the center channel.[​IMG]

    For $30, an SPL meter is pretty much the best investment in audio.

    I use mine for all the above but also:

    I used it to see which car of my friends rides are the quietest.

    How loud my commercial theaters are during THX intros.

    Who can scream the loudest

    An spl meter is also loads of fun at party's.
    Take readings during first cocktail.
    Take readings during second cocktail.
    take readings of your buddy's voice after he's had too many (you know the loud one, everybody's got one)
    Take more readings after everyone is laughing about how loud the loud guy is, 110 db baby, yeah.

    My SPL is a must have. Anytime I do the smallest changes in my room I break out my SPL meter. It was amazing to see the first time that I calibrated my system I realized I had all my settings set too high espcecially the rears. Now the sound is more realistic and natural.

    It would be cool to see new receivers come with a SPL meter. Or at least give you a rebate to purchase one for free from RS in case you already own a SPL meter.

    With electronics and signal processing advancing as they are, I sure hope that my next receiver in two or three years comes with a microphone to place in the listening position, and then the receiver can auto-calibrate levels and equalization. I don't see any good reason why we still need to do this manually.

    Eric,

    Right now the Pioneer 49TX comes exactly what your asking for. The new Pioneer comes with a feature called MACC. It includes a microphone and does everything automatically. Not only does it calibrate the levels and distance, but it also EQ's the sound depending on the size of your room. This feature has been highly praised by many members here.
