(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

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 38.
