I have a Yamaha HTR-5540 with the matrix 6.1 processing. Unfortunately, it doesn't have pre-amp outputs. I'd have to drop the amplified rear channel signals with a level converter in order to connect to an old pro-logic reciever.
My question is : do the amplified rear channel signals still carry the matrixed encoding that teh pro-logic reciever can read, or has the reciever already "cleaned" them out by the time they've reached the amps?
If the encoding is still there, would I want it on regular 5.1 mode or the 6.1 mode?

Thanks for your help

The signals are still there, mixed in with the left and
right surrounds. Yamaha's matrix 6.1 is just a manipulation
like SRS sound, designed to kind of simulate a centre
rear channel. None of these techniques works like a real
speaker. Try it with the 5.1 and see if you can get decent
results then try it with the 6.1 mode to see what it sounds like. Most of these matrix modes (phantom style, no speaker) tend to bleed more sound into other channels
so the discreteness of 5.1 is compromised and the overall
sound is weird. Sony's got a bunch of them for 4,5 channels
in the rear of "phantom" speakers. You can't beat the real
thing.
