Burst Power

Burst Power is used for measuring the dynamic power of a power amplifier. Burst Power measurement provides information about power reserve and power supply resources of an amplifier, as well as the output capability of the output devices. It is usually done with a 20 ms sine wave burst followed by a considerably longer period at a lower level. QSC for example use 480 mSec at -20 dB.
Editor's comment: As far as we know there is no general standard published yet. But manufacturers (Yamaha, QSC and more) all use a 30mSec burst.
