Here's the deal: The receiver appears to have stopped recognizing the bass signal from the CD player. It's fine when I play a CD in the DVD player, or when I play a tape on the tape deck (remember those?), but I get no bass from the CD player anymore (this is new- it was fine last week). What can be the deal here? Is this a player issue- has anyone heard of this before? Can it be the receiver? It doesn't seem like it to me. Getting to the back of my system is a big deal, as it is enclosed in an armoire. All settings are correct. There haven't been any new adjustment made to the settings, any wire changes, nothing, nada. I don't want to reset the receiver and lose the programming just yet. Any thoughts?
