Well, both :-) Actually if it is dynamic range and an amp can do a dynamic range of120dB or more but I turn it down so the loudest level is 60dB SPL atmy ear, the smallest level will be 60dB-120dB=... well, it will besilent enough to be not to be heard.

We are talking about music-production for the mainstream and PA, notmusicians amps. :-) I haven't seen anyone firing his home equipment to have 120dB andsitting 1m or less away from it... <snip>> 120 dB dynamic range is an incredible amount, it corresponds roughly> to the difference between whispering and a rifle fired at 1 meter.> Even the humble CD can capture the difference between whispering and a> chainsaw. 120dB is the difference between just loud enough to be heard by yourear (1dB) and the loudness when the bones in your ear bow to protectit. At higher levels (>120dB) your ear aches but it will recover ifthe noise isn't permanent. At least thats the definition I learned...

Agreed! :) (*) At least if my physics aren't completely wrong...-- visit http://www.arnoldarts.de/---Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklichverhindern könnte, würde ich mir noch heute einen Stapel Brenner undeinen Sack Rohlinge kaufen.
