    All,

    Does anyone know at what db I must measure the spl when use the Sound & Vision DVD for speaker calibration? No where on the DVD that gives a definitive setting instruction except for the chapter "how to use the RS meter" that shows the setting at 70. Based on what set in this chapter, I calibrate the speaker to 75db. The subwoofer has a 5db hot.

    Not sure that 75db is a designated level for this S&V DVD.

    In my opinion it doesn't matter so much as long as you get the volume set identically for each speaker at a level you are comfortable with.

    Tam,

    I agree with James. I set my receiver at what sounded like the level I liked than calibrated all speakers to match.

    Thank you all. 75db is the level I calibrate at. Well I just leave it at that. With this calibration level, my ref is at -10db, which is at sometime i measured the peak spl at 100[​IMG]

    Since calibration levels are specifically coded on the DVDs to calibrate the playback level based on specific recording levels, one should always use the -75dB level for VE and the -85dB level for AVIA.

    Since this DVD is a somewhat pared down version of the AVIA DVD, I would expect the 85dB calibration level to be the correct one, unless instructions say otherwise.

    Our ears are not as sensitive to lower frequencies at lower volume levels (Fletcher-Munson curve). I'm not sure, but if you don't calibrate to the recommended dB level, you may not get bass levels represented properly during DVD playback.
