Balance issues?


Hey all. I'm having this issue when I adjust the balance control on my Cambridge Audio Azur 740a all the way to either the left or the right, I am still getting signal out of both channels. I have checked my wiring a thousand times. 
When I hook up a different pair of speakers, same issue. When I reverse the wiring, same issue.
When I switch to my other older amp, balance works as it should. 
Is it possible there is a problem with the azur 740a?
When balance is at zero it sounds ok, maybe even in the middle. But I can't help but think it sounds under performed. I should mention I bought this amp used.
Thanks

You should be able to set your balance control so that the central image, usually the vocal, is right in the middle of your soundstage.  If you can't do that there is a problem with your balance control. 

You don't say how loudly the L or R channel plays when you have the balance control set all the way to the other channel.  If  it's more than minimal volume, that would indicate a problem with the balance control also.

Thanks for taking the time. When the balance is all the way to the left channel it is definately louder than the right and vice versa, but doesn’t silence the opposite side as it should.
Some designs DO NOT SILENCE the other channel fully. The balance knob is not to create one channel mono. just 'balance'. So I would suggest if you manage to get in touch with the company, they will tell you that is how they designed it.                        
Good luck.                
When the op writes "as it should'. You are not really saying it must, (or it is not a balance control) you are saying it is what you EXPECT. Sorry that the device does the job (balances the signal), but not what you expect. (shuts off the other channel completely)
