What does PMPO stand for?
PMPO stands for “Peak Music Power Output.” It is a term commonly used in the audio equipment industry to denote the maximum power output of a sound system or speaker over a short burst of time. This measurement is particularly important for consumers shopping for audio devices as it indicates the capability of the system to deliver peak volume levels during audio playback.
However, it’s crucial to understand that PMPO does not represent continuous power output, which is typically measured in RMS (Root Mean Square). The PMPO value might appear inflated compared to RMS ratings, leading to confusion among consumers. Therefore, while PMPO can give a brief indication of power potential, it should be considered alongside other specifications for a comprehensive understanding of an audio device’s performance.
How is PMPO measured?
PMPO is measured by taking the highest level of power that an audio device can produce during short and intense bursts of sound without distortion. This measurement is often conducted using specific electrical and acoustical testing equipment that pushes the product to its operational limits. Manufacturers will often conduct these tests in ideal conditions, aiming for an impressive result.
