(1)Filter condition:
THD+N: 20-Hz HPF, 20-kHz AES17 LPF
Dynamic range: 20-Hz HPF, 20-kHz AES17 LPF, A-weighted
Signal-to-noise ratio: 20-Hz HPF, 20-kHz AES17 LPF, A-weighted
Channel separation: 20-Hz HPF, 20-kHz AES17 LPF
Analog performance specifications are measured using the System Two Cascade audio measurement system by Audio Precision in the averaging
mode.
(2)Dynamic performance and dc accuracy are specified at the output of the postamplifier as shown in Figure 37.
