Is this dangerous ?

I am trying to incorperate my 2 channel and home theater without comprmising sound .

Here is what i want to do : keep my 2 channel amp wired to the speakers as usual , the speakers are biwireable. I want to use the second binding posts on the speakers for a receiver for home theater .

Both sources would be wired at the speakers . I figure if only one source is powered on at a time this would work .probably use a independent powerstrip for each and keep the source i am not using turned off at the strip .

My main question is if both sorces would send a signal to the speakers at once what would i hear ? would it mix the two together and make some funky noise ? Would this damage the speaker ?

You can try it and see what happens. I would certainly never do that. And I'm assuming you have jumpers between the 2 sets of speaker jacks.

Wouldn't the signal feedback through the second set of cables?

Hopefully, one of the electronic techs will weigh in here. But until one does -- I advise don't do it.

As Meiwan surmises, I too suspect that if both amps are tied in simulataneously, the outputs will short unless the amp not in use is disconnected from the circuit.

Perhaps a call to the factory would be worthwhile.

Is this dangerous ?
Yes, it absolutely is dangerous, mainly to the amplifiers. The outputs of two power amplifiers (or the power amplifier section of a receiver or integrated amplifier) should never be connected together. See this thread for further explanation, and for suggested solutions.

Get a 2-channel preamp with a home theater bypass circuit. Then follow the instructions on connecting it all together.

Or, if your HT receiver has preamp outputs, connect the Left and Right front channel pre-outs from the receiver to a pair of line level inputs on your amp (or preamp--you're not very detailed on what your setup is).

If your AV receiver doesn't have pre-outs, sell//trade it to get one that does. The ones that do aren't that expensive.

My plans are to get a pair of tube amps for 2 channel which i do not want running day and night . I can either unplug the receiver when not in use or swap the speaker cables each time. Lots of wear on the bannanas that way though . Unplugging the receiver is probably the best and safest way . I do not want to invest in expensive items to remedy this issue. ie: new bypass preamp.
