Bridging channels on multi-channel amp

[bradandbree]

I've seen that some recent high-end receivers allow bridging some of the channels to increase power to those channels. I have a 5.1 system with no real intention of moving to a 7.1 system, but I'm planning on getting a new receiver for other reasons. If I were to bridge the left and right rear surround channels (6 and 7) with the left and right front channels (1 and 2), I would have more power driving my mains, which would be great for 2-channel listening. But does this have a negative effect on the center channel or surrounds when the power is unequal?

are you talking about bridging or Bi-amping?
most receivers with the bi-amping feature let's the user choose between a 7.1 setup or a 5.1 setup + bi-amped fronts.

if you were to bi-amp the front channels, there will be no negative effect on the other channels because you are supposed to level match them anyway.

btw, this also applies even to bridged channels.

Or did you mean biwiring?

You cannot biamp unless you have separate connections (high and low frequency) on the rear of your speaker.

Sorry about my terminology. I did mean that bi-amping feature of 5.1 + bi-amped fronts, and just assumed that's what bridging meant. Glad to hear that this can provide some benefits. Thanks.

No, I don't really have any interest in bi-wiring, but I do appreciate your help with my question. My speakers are indeed ready for bi-amping.

Thanks again to both of you for your input.

Bridge amp channels

You cannot bridge the amp (or receiver) channels unless it is specifically designed for that purpose. A receivers with the "bi-amp" feature is different from bridging the amp channels and you need a speaker with 2 sets of binding posts.
