It seems that I have to buy a precise voltmeter or good digital oscilloscope to get these results :-) Anyway, the voltage levels expressions are described nicely here: http://en.wikipedia.org/wiki/Decibel >From above pro-equipment works with 0.775V as reference volume (0dBu) and consumer electronics with 1V as reference volume (0dBV).
