PMPO (Peak Music Power Output). There's no technical definition I can find for this, but it appears to be marketing speak for: "Let's find any excuse we can to advertise more watts"! So we use the peak power rating mentioned above (a fictional double of the RMS power), usually a stereo system, so double again, then sprinkle the fairy dust
. There are suggestions that because some music played on these systems is highly percussive (such as techno), that the system can deliver much more power to handle these peaks for very short times. This mutiplies the figure yet again by some arbitrary figure, but more importantly, it's very relevant to guitar amplifiers.
Said Eddie Robison, "Our deadline, coupled with a massive number of shots, presented very specific challenges on this project. Our approach to the overall look was a sort of stylized version of reality, rather than absolute photo-realism. We used a lot of dramatic camera moves, and some flashy tricks I've learned over the years, to really sprinkle on the 'fairy dust' and bring this animated story to life!'"
