I think the idea is that is the average level is 0dBV on the meter, you
still have 20dB headroom for peaks. If the +20dBV level is 14V (max
opamp output), 20 dB below that would be about 1.4V peak. Now we can
get into another argument about where the average for music is... is
it .707 like rms for a sine wave, or .637 like avg level for a sine
wave, or just .5 or 6dB like 'music power'?
dBV isn't used much these days for audio.
What do you mean by an average anyway ? The dynamics of different styles of
music push the level allo ver the place from one moment to the next. The
concept of average isn't teriibly helpful. You need to avoid distorting the
loud passages.
