Ron and Tom, I'm sort of mystified about the various controls and whatnot on my new 16-PC46, and the manual isn't terribly helpful. In particular, what is the purpose of the +3dB and +6dB bass boost switch? When would someone want to use this? Really, may I suggest that for the PCs that you include in the manual a more in-depth discussion of what all these things are and what they're used for. The present description is pretty scanty and seems to assume that we already know all about them (not all of us do). ------------------ "This movie has warped my fragile little mind."
