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

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)

This is how most balance controls work.

Since usually balance is only off a few dB, you don't want a very wide range balance control. Something that adjusts maybe +- 6 dB to +- 12 dB is more than ever gets used. This lets you adjust with finer control.

Best,

I like the fact a balance knob usually shuts off one channel. It allows one to 'check' for various problems! (also, in the past, audio books sometimes used a technique of having one stereo channel to be a separate set of book chapters from the other stereo channel (which could become extremely frustrating if no ability to cut off one or the other channel... like in a car) or apparently the Cambridge Audio Azur 740a
