In your High Level Amplifier example:
Rated output is 1V
Total High Level Harmonic Distortion in the next line is given at 5V.
1V does not equal 5V
In the next example
Rated output is 2V
The specs for distortion are given at 8.0V, which is also given as the maximum output.
The examples you have included don't support your claim. The 3rd example doesn't support the "never" claim.
It's always good to take a deep breath or two, when someone disagrees with one of your posts, before you reply.
It's probably a good idea, to take that breath and perhaps go read, say a few hundred listed specifications/service manuals for preamplifiers and then come back with your findings on consistency and truth in specifications.
Rated outputs are one thing, maximum outputs are another. The examples I listed above are just excerpts from considerably more comprehensive specifications for the two preamplifiers concerned. Comprehensive, in that they separate the high level, low level stages and specify them individually. Both preamplifiers I have sitting right here, should you have any more queries.
The
rated output of the first example preamplifier is 1.0V. quite clear (as is the JC-2).
The
rated output of the second example preamplifier is 2.0V, again, quite clear.
The frequency response, signal to noise and other parameters are referenced to the
rated outputs. Where they are not, it is specified.
The second example THD <0.005% is referenced to the rated output of 2.0V on
any inputs (Accuphase guarantee a worst case figure for any input) and, as a bonus, it also is achieved at 5V out on the RIAA EQ and Line stage.
So, if you want a discussion on specifications, truth in specifications and ratings, start a thread on it- I'll be happy to add my two cents.
