Here in the USA, it is not uncommon for television stations to turn up the volume during commercials. Normally, this is not that big of a problem. Lately, I have noticed that the volume goes WAY up during some commercials. I called a couple of different television stations today, and they insist that they do not turn up the volume to any significant degree during commercials. Because I do not notice that significant of an increase on my den or bedroom televisions (utilizing their built-in amplifiers and speakers), I was wondering if this could be problem inherent to my Arcam AVR300. Any thoughts?
