Hi David,

If you are refferring to L/R back being the center, it is possible, but you would need a seperate decoder/receiver such as Larry Fine's setup.

You would route the L/R rear signal from a line level output to the secondary decoder/reciever and then set that up to run at 3 channel pro-logic mode, which will give L/C/R rear.

The only way to run it as you propose is to have a receiver or pre/pro that has this possibility. I know certain Yamahas do, but I am not sure of the other brands that have this capabilities....Tony
