Home Theater Setup

Sounds like you have a short in that wire or connection somewhere. Disconnect the speaker wire for that channel from Denon and try it again - it shouldn't shut off then. If it does, the unit is defective.

Look at the speaker wire at both ends and make sure there aren't any strands touching the other connector on the speaker binding posts - this is the most likely culprit...

I just looked up the owner's manual for the PC600. It looks like there are two ways to hook up the fronts and sub.

First is to run the speaker wire from the receiver to the sub, then to the L and R speakers. Sounds like this is the way you did it. Seems weird, but this is the way Def Tech recommends it. Set the L and R speakers to "Large" and no sub in the receiver.

Second is to run speaker wire directly from the receiver to the L and R spekers and to connect the Sub with an RCA cable to the receiver. This is the more conventional way of hooking up speakers, but like I said above, for some reason Def Tech recommends the other way. Set the L and R speakers to "Small" and Yes to the sub in the receiver.

And it sounds like you either have a short in the LR speaker wire or speaker. Try running temp wire to the LR and run the setup again. If is still shuts off, try swapping the LR and RR speakers while still using the temp wire and see if it now shuts off with the RR speaker. This would let you know if the speaker is bad. If is still shuts off on LR, it may be a faulty receiver.
