[QUOTE="Moble Enclosurs, post: 7555993, member: 634917"] You are not seeing a drop because of clipping, but because each frequency has its own power level, thus measuring voltage when a song is playing, you will see it jump all over the place. But going back to what was said about setting voltage to 1500@1 around 38V, this is a good response and is acceptably accurate. But you cannot judge voltage on multiple frequencies, like a song, because again it will jump. But this is not due to voltage drop, but recording capabilities of the -3dB tone vs the recording of the song, which can vary upon each song if they are from multiple sources. So, you will likely always see a lower voltage from a test tone to a song, because of the recording quality and output when played. If a song is copied multiple times, if not digitally, to retain quality, this will effect voltage as well. So, go with the idea given of 38V setting with a test tone, and disregard the changing voltage of a song...this is normal. [/QUOTE]
