I am putting a pair of Icepower 200asc class-d boards into separate boxes. Do you need, or should you use a AC line filter with these? and if so, any recommendations.
Good question! I think it would be a good idea. I don't know what sort of filtering the Icepower modules have on their AC lines, but a little extra, to prevent excess noise polluting the AC power, and getting into other, sensitive gear, is a good idea.
