    Absolute level cal with REW generator and SLM

    I'm having a tough time level calibrating my new Anthem AVR MRX 1140.

    Calibration Of Soundcard

    Hello Everyone, I calibrated my sound card but the high end looks odd. Why wouldn’t it be a flat line? As you can see it’s affecting the room measurements in the opposite way. Plus phasing look weird.
