    Messing with the wiring this way is certain to release the magic
    smoke. Wire it up the way they say and rest assured that neither your
    CDs nor your vinyl will be reproduced in surround. They will play
    perfectly normally in stereo through the front left and right
    speakers.

    Confusing using a modern 5.1 system with the trick we used to use of
    connecting the two rear speakers in series between the two positive
    connection on the front ones to extract the out of phase reverb?

    I didn't expect them to be reproduced in true surround, I just wanted
    listen to them only from the front speakers.

    I have two other complete (non-surround) stereo systems in my home so I
    guess I'll just listen to my CDs and LPs on them.

    Or maybe I can just use the "+" and "-" center and rear level controls
    in the front of the surround-sound receiver, it would be helpful if
    there was some kind of graphic indicator for those on the front but it's
    just the four buttons. Then you're supposed to run some test with a
    sequence of beeps coming from each of the four speakers to get the
    optimum balance from the front and rear.

    BTW this receiver I'm using isn't even a more modern "5.1" surround
    type, it's an old "Dolby Surround Pro-Logic" from early in the century.
    I have HDMI running from the Blu-ray player to the TV but for the TV's
    audio out to the receiver I use the old RCA jacks (the only kind the
    receiver will accept).

    Please stop. Just put it together exactly as recommended. Stereo
    sources will produce stereo sound from the front speakers. If you hear
    stuff from rear speakers you have turned on Pro Logic. Turn that off.

    You are simply inventing problems for your self.

    No. When it is going through the surround decoder, it will route the appropriate dematrixed signals to the center and surround channel. The dialogue will be in the center, the ambient rear sounds will be in the surround just the way it was mixed.
    I was just interested in hearing CDs and LPs from the front speakers
    only with a surround set up, the way I've been listening to music for 50 >years.
    I am not sure what you mean by this. Those recordings are not recorded in surround. If you were to run them through a surround decoder the effect
    would be unpredictable with the stereo image constantly moving around.
    With my previous straight stereo receiver I just had the front speakers >hooked up to "A" and the rear speakers hooked up to "B" and I could turn >the rear speakers on and off when watching video or listening to CDs >accordingly.
    That would give you the same signals in the front and rear, and no surround effects of any sort. No center channel either, which is really annoying if you aren't sitting on the center line of the room.

    Tickled my surround system in Pro Logic / PLII quite pleasantly and with much stability. Especially the lead vocals. The percussion and rhythm stayed focused in
    the center channel, with the vocals and reverb evenly spread between front mains and
    surrounds.
