    Default Bi-amping a speaker ?

    Hi all, I have a question abut bi-amping speakers.

    I have read in some manuals, that I can use channel 6 and 7 if not in use to bi-amp the main speakers.

    What that means to me is that I will take speaker cable from the receiver's rear channels (6, and 7) to the dual connectors in the back on the main speakers.

    If this was to be done using an amp I guess I will interconnect the rear channels from the receiver to the 6, 7 channels on the amplifier and from the speaker terminal in the amp to the main speakers.

    I hope that I have above info right?.

    Finally the question: I have also read that there is no need to amplify the 4, 5, 6, and 7’s (surround and rear surround) channels since they actually contain small amount of sound compared to the main and center channels, which I agree since I have a 5.1 setup.
    If this is right, wouldn’t it be that if you use the 6, and 7 channels out of the receiver, then the results would be rear surround signal going to your mains which in my mind would be: 1 the wrong information going to the wrong speaker, 2 very small amount of sound, (again rear surround signal) going to your mains which will actually make the sound not as good as just simple not using the bi-amp capability.

    What am I missing where am I going wrong with my logic…

    I think you will find what you need to know here.

    Plus the drawing below shows how it is done with an NAD T-773.

    Hi all, hearingimpared thanks for the link.

    I have done a bit more research into this and this is what I found.
    The pioneer elite vsx94txh the latest version of the elite series. The manual says that you can use the surround back connectors for Bi-amping. The way it is acomplished is that you will set it up and then you go into the settings and set it to Bi-amp. The older versions the only settings available were on, off, auto, but this just meant for the receiver to detect the surround back speakers.
    The new setting seam to say the processor will send main signal info to the surround back connections if set to bi-amping which is what I though need it to happen.

    I hope this is helpful.

    My AVR sets up the same way with unused rear channels. Works well and helps to feed my hungry 9's.

    Never found biamping to help much unless using a tube amp for the mids and tweets and a solid state amp for the woofers. The logic is that the tube amp will provid better highs than a solid state amp.

    I was considering this when I was looking for an amp to power my tweeter arrays. The reason I didn't go with it was because I was advised that tube amps and sand amps have different speeds and they would sound out of sync with each other.

    Do you actually have experience with bi-amping with a tube amp on the highs and a sand amp on the lows?

    PS: when I bi-amp'd my 1.2 TLs with two sand amps, this made all the difference in the world sonically for the better.

    I biamped a tube amp and a sand amp many years ago. Did it with a Nikko Alpha 230 and a Dynaco (I think) tube amp on my DCM Timewindows. Can't really remember that it made a huge difference, but there's a good chance that I've killed those brain cells over the years, too. Looked cool, though.
