    I have an Elite VSX-37TX. IN order to take advantage of the 7.1 feature, I need to use a second amp for the back surround. I want to try this out using the old Elite as the second amp. I need some guidance on the wiring. The manual only indicates where to go out from the 37TX. What do I input to on the 2nd amp? Which speaker terminals do I connect to on the second amp?

    Any suggestions?

    thanks!

    If the old Elite is a receiver, 2 channel, it might

    have something on the back called, "Main in" and "pre-out"

    which means you can break the amp-preamp chain in it and

    use it's internal amp. You'd just plug your rear-centre

    channel output from the new Elite into the "main ins" on

    your old one and you'd use the speaker outputs on the

    old amp to power your rear centre channel speaker.

    If it's an older surround receiver, it may still have

    "main ins" which you can use. Some older surround

    pre-amps had these "main ins" in addition to the

    regular, volume-controlled inputs for CDs, phonos, tape

    decks, etc. If you don't have a main in, you could simply

    plug in your centre outputs from your new Elite into

    any of the inputs for those other devices. You'd then select it as the output device on the old receiver

    and you would have to work with the old Elite's volume

    control and centre rear output control on your new

    Elite to obtain the level you need from the rear-centre

    speaker. You might experience some noise if you are forced

    to do it this way since the old analog source will no

    doubt add some noise. You may also have "gain" problems.

    Hopefully, the old Elite has a main input.

    Lastly, you can either plug the centre rear output

    connector into only one input on your receiver (either a

    left or right channel input) but this could (but may not)

    cause some problems because the old receiver expected to

    receive dual inputs, L and R, just like from any old

    stereo source like a CD player. If your new Elite features

    dual rear-centre outputs, use them both, plug them into

    the left-right channel main inputs on the old receiver.

    If your new Elite does not have dual outputs, then you

    can use an RCA 1 to 2 splitter (Radio Shack) and then

    it will match with the left-right stereo component input

    on the old receiver.

    Good luck!

    Hey Ed,

    Nice to see another Elite owner posting! I bought the Elite amp for my system instead of using my old (3 yr) Yamaha receiver to drive my rear channels. Sounds incredible and a much cleaner setup to show off. If you don't have a SPL meter yet, get one! I was suprised at the improvement in the soundfield of my system after I calibrated the right way.

    Make sure you post again and let us know how you like the sound with the rear channel working.
