    Can 5 speakers, when coupled with a receiver capable of the 6.1 formats (DTS ES and DD-EX), 'phantom' a sixth speaker?

    Clearly the effect won't be as discrete, but is it possible, and does it make a difference?

    ALL receivers that recognize 6.1 "fold" the rear center info into the 2 regular surrounds if the unit is setup with no rear center.

    Would one consider it a "phantom" setup? I guess it depends on one's terminology. I do think it's fairly safe to say that anything that would have been sent to the rear center would be sent to both surrounds. I am certain that nothing is lost.

    Marantz 6300 manual says nothing about that. Are you sure all receivers "fold" ...

    Yeah, they fold. (Or if you're not comfortable with my term fold, how about retain or blend?)

    If they did'nt, you would be losing part of the signal. Both 6.1 DTS and DD discs do not lose any of the program if you stay as 5.1.

    Re: Yamaha 5540 Reciever:

    From Yamaha's website:

    POWERFUL SOUND PROCESSING With powerful and varied sound processing, the HTR-5540 provides Dolby Digital, Dolby ProLogic II, and DTS Digital Surround decoding. Yamaha's Quad-Field CINEMA DSP allows enjoyment of Dolby Digital EX and DTS-ES Matrix 6.1 sound formats in the ***Phantom mode (using 5.1 channels)***. The HTR-5540 provides 21 surround programs and offers a total of 41 surround environment variations.

    ))))))))))))))))))))))

    As someone who does have a 6.1 set-up, I really can't see how this "phantom" mode would equal a true 6.1 set-up, but maybe the effect would be halfway decent, I don't know.

    I believe that the Pioneer VSX-811S has what is called a Virtual Surround Back mode. Ill check my manual when I get home to see exactly what it does.

    In any case, phantom or not, the rear info is still played by the rear speakers in a 5.1 setup (basically the definition of EX).

    My former setup was 6.1, but in my new place, I physically cannot have a rear center. The lack of the 6th speaker is very noticable on EX/ES material.

    Guess you're right, it's weird that they would do it that way.
