Hi Folks. Why is the K system calibrated at 83dB? It feels too high a level to work for hours on end. I went to a professional mixing room today and calibrated the monitors to 83dB according to the Ksystem guidelines: 1. Setup a pink noise generator at -12dB (-12dB, -14dB or -20dB, depending on desired K-Scale) 2. Move monitor output level knob until dB meter at sweet spot reports 83dB I proceeded to play some mastered music and felt this level was way to high for my taste. Did I do something wrong? How do you callibrate your levels to work with K metering?
