Thankyou for your reply Ben. I understand where you are coming from. Many moderators have far too much to say, and i know we dont want that. There have been times when i felt an informed response from you would be appropriate though. Like when we are continually hashing and rehashing an issue and not getting far with it (exasperating remote problems come to mind).
I, for one, would like to see you jump in more often, with informed information like you just provided about the sub/lfe trim. Ive wondered about that for years, and now i know where the designers were going with that! Manuals do not always explain things intuitively.
