What does the volume setting actually mean ?

    Hi All,

    I'm sure this applies to other amps as well, but I have a Sony STR-VA555ES amp and the volume goes from:

    - infinity dB

    up to

    -0 dB

    I.e. the first is zero volume up to the latter which is fecking loud.

    If I have the amp at -65dB does that relate in anyway at all to the actual amount of noise in the room or is it just some figure plucked out of thin air that indicates in some way how hard the amp is working ?

    Cheers

    Ian

    Think mine goes from -70 to +15 - quiet to loud - its a Denon.

    From what I have seen all manufacturers have their own system for describing volume levels, with no consistancy.

    Like micb3rd said its in DB's with 0 being the reference level and supposed to be the Dolby reference level. Although they are set up in the factory they will all be different depending on the equipment etc used so you still need to calibrate the system yourself with an sound pressure meter.
