(1) Filter condition:
THD+N: 20-Hz HPF, 20-kHz apogee 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

Analog performance specifications are measured using the System Two
t 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 36.
(3) Dynamic performance and dc accuracy are specified at the output of the postamplifier as shown in Figure 37.
