  1. Doing SPL tests on an advanced PA system.

    Important when you do this work is to have proper PPE on your corpus (latin).

    The system was running between 37dB SPL (sound pressure level) and a massive 110dB SPL. Note1

    It's important to keep your corpus safe so a proper set of earmufs is a must.

    This PA system can run all the way up to 125dB SPL but that level was not needed in this test. The signal limiting systems were tested with this setup, since those are the last stop between your speaker systems the signal and burning speaker coils...

    Note1
    My dB meters are calibrated so the values are accurate. I use one consistent system of calibration accorss all my dB meters to get similar results on similar acousting ENV
