Good question. In general, I think analogue gear uses dBVU (Volume Unit) unless otherwise stated (like a PPM {Peak Programme Meter} for recording programme material to digital storage media). Digital equiment uses dBFS (Full Scale) to give a good (ish) idea if you're clipping.Originally Posted by Basil Rush
Digital distortion is nasty. Analogue distortion is far more forgiving, and can be beneficial.
