8 Parameter Measurement Information

All parameters are measured according to the conditions described in the Recommended Operating Conditions, BTL Configuration, SE Configuration and PBTL Configuration sections.

Most audio analyzers will not give correct readings of Class-D amplifiers’ performance due to their sensitivity to out of band noise present at the amplifier output. AES-17 + AUX-0025 pre-analyzer filters are recommended to use for Class-D amplifier measurements. In absence of such filters, a 30-kHz low-pass filter (10 Ω + 47 nF) can be used to reduce the out of band noise remaining on the amplifier outputs.
