I'm thinking "what setting?!"
Do they mean a f/w setting or what? Either way, it sounds like the problem's been resolved.
But then there is this weird thing, why did some users notice the noise also with P.EQ and some did not? Sadly no one answerer to my firmware version question. Now I noticed, that some user had fw version 1.000, but my unit had 1.001. So did Alpine release even more buggy firmware after the initial version and I was one of the "lucky" ones that had it? This latest fw version is 1.003.
