Yamaha PEQ
Bassman,
I have a comparable Yamaha HTR-5860. As you described, my receiver has an Automatic PEQ or a Manual Center EQ. It will not let you manipulate the results of the PEQ like higher end models. In my experience, the PEQ features on this and other entry level receivers are not much benefit. I leave the PEQ off and for 2 channel use the pure direct mode.
