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 24.

(3) Dynamic performance and dc accuracy are specified at the output of the measurement circuit as shown in Figure 25.
