The parameters are as follows unless otherwise
specified.
The word clock (FS) is set to 96 kHz.
Only the channel being measured is ON.
PAN: Center
GAIN : MIN
PAD : ON
FADER : NOMINAL (0 dB)
0 dBu = 0.775Vrms
0 dBV = 1Vrms=2.2 dBu
0 dBFS = 0 dB full scale
The oscillator output impedance is 150
Ω
.
The oscilloscope, level meter, etc. input impedance
is set to at least 100 k
Ω
.
Noise measurement is corrected with a 12.7 kHz,
-6 dB/octave low pass filter.
(These are not effective values, but measurement
with average values.)
Distortion measurement is corrected with an 80
kHz, -6 dB/octave low pass filter.
For analog output inspection, the following
parameters are added or changed.
For maximum output measurement, unless
otherwise specified, output 0 dB from the internal
oscillator.
