Please help in setting up a SONY STR-DE875 before it goes into PROTECT MODE!! All my revious receivers have allowed the independant selection of front and rear speaker channels with the turn of a dial or the pushing of buttons. This allowed the use of either the fronts, the rears, or both using any component (particularly FM, and CD). Is this possible with this model? I have been through the manual five times, and Sonys help line was less than helpful. One would think the answer lyies in the surround set up options but I am beginning to think this too much to ask. The closest I have gotten is a 2-channel swap mode, which swaps the output from front to rear (until you touch ANY buttons on the receiver or remote).For all the new technology, I am serouslly contemplating hooking up my old Teac AV-30XXX, which lacks 75% of this sonys surround features, but has two nice buttons for speakers A & B. ANY help is greatly appreciated. Thanks.
