I have an AtlanticTechnology T70, 5.1 speaker system with a T70 PBM powered subwoofer. It is connected to a Yamaha RX-V659 AV receiver. Last week I suddenly realized that my subwoofer is not working at all. I emailed Atlantic Tech and they sent me info. on how to test the sub. Both the sub's amp, and speaker are working according to the tests BUT there is no sound coming out.


I've checked and rechecked the AV Receivers settings (speakers set to small, sub set to Subwoofer.) All sound level settings are OK.


I've also checked the wires and have used 4 diffferent wires to check but no sound from any of them.


It seems that the AVReceiver isn't sending out any signal but I don't know how to check that.


Any suggestions on what to do next? I spent about 6 hours, yesterday, checking and rechecking. No Sound.

What connections are you using on the AVR and the sub?

What are all the settings on the sub?

Does the sub show that it is powering on?

What are you using for the sound source?

What mode is the AVR set to for the input device?

What speakers channel icons are showing on the AVR front panel for input and output?

Oh, my god not another member with, blown sub bass!

You didn't say if you had a power LED light on the sub? If that is the case then check mains plug fuse then open up the sub and look for slow blow fuse and check it to see if it's blown!

Sorry. Fuse is OK.

Because the SW icon does not show, then the AVR is not routing anything to the sub. I suspect you have some mode set to stereo instead of one of the multichannel modes.
