That helps a bit, V. Big Grin | :-D

By the way, honest manufacturers have always used RMS ratings; only a few played dirty using other terms. RMS is simply an acronym for a mathematical formula - Root-Mean-Square. What it means is that, for each point on a signal waveform, you square the value first, then calculate the mean of all the values. Since an ac signal has positive and negative, calculating the mean directly won't work, since most of the samples will be cancelled out by equally valued samples of opposite sign. The last step is to take the square root of the mean to return the value to a real scale. The reason we use RMS is to compare apples to apples when dealing with random samples of music signals. No matter what the wave shape might be, RMS reduces it to a common measure. It's easy to explain mathematically, but difficult in words. If you're curious, I'm sure Wikipedia has a decent explanation, with examples.
