I have a Yahama RX-V1300, when I try to shut off the "A" speakers, they stay on. Also is there a way to shut of the sub woofer when turing of the "A" speakers? Any ideas?

Hi, I have an Rx-V1300 and dont have any problems with the speaker set 'A' not turning off. Does the 'A' & 'B' icon appear and disappear on the little screen?

Not sure about the sub, have you got a manual?

Assuming you have checked that the A and B outputs are correctly wired to the speakers and that the + & - leads have not been transposed with the B anywhere.
Because you can bridge/paralell) these two outputs to create one huge power output, Im guessing this is why you cant shut down output A properly 

Usually you can select  A, B  and A+B   therefore   if you have bridged the outputs the speakers will essentially be in mono (but who can tell anyway), with a higher output. 

AS for switching off the sub, does the remote not have this function for SW volume?  Does the sub have its own power on/off?  
You could try installing a small switch to make it eaiser.....   id personally go for the remote option.

Because the sub is recieving the low freqs from the amplifier, its not a good idea to wire this with your A output ! 

(assuming the sub output is dedicated). 

I guess you could wire it to the A output, but make sure you use a decent filter/crossover at the sub....but then again ya would have just reduced the impendance of this entire system....  so not really a good thing to do !

I do have the icons for A & B. The A icon disappers when I push the buttopn, however the center speaker and the sub stay on. I also have the manual and have checked to make sure I have the wiring correct, at least I think I do. Thanks for the reply.

Thanks for the reply & info. I will recheck the wiring. I am told by a Yahama dealer that the sub should shut off when I turn of A. So far no luck.

Hey dude, 

I just read the manual for your amplifier,  very nice ! 
Anyhow, it might pay to check your "speaker set", "set menu settings"  on page 24. 
Also make sure you have selected the correct impedance. (look on the speaker itself). Just remember if your using an 8ohm speaker on a single output and then add another speaker to that same output, the impedance will be reduced by half.

Good luck. 

How many speakers are you using?   
Page 25 shows you what settings to use for different speaker set ups.
