They aren't really indicating volume in dB, they are, as you noted,
showing the amount of *attenuation* between pre-amp and power amp in
dB. Very different thing.
hmmm ...
well, if you look at the "tradition" i was trying to point out, while the
number on the dial seems to literally mean attenuation in the case of my
receiver, it's clearly something else in the case of Rick's; the reference
point and the direction are different, but what is consistent is that effective
relative _volume_ is being _indicated_ in dB; so i think my use of the term
"indicating" is accurate whether or not actual spl (sound pressure level) is in
direct proportion to these values
