This sounds similar to what was reported here:

David Young's solution might fix your issue too.

If it's only a matter of removing the back plate, it shouldn't void your warranty.

Hi Malcolm,

you wrote that the two satellite speakers work normally, but the Subwoofer doesn't. This means that the problem MUST be with the Subwoofer, because:

The satellite speakers are passive, so these two amps (which are built into the Subwoofer) work.

The stereo signal from the Genos to the Subwoofer (via the 8-pin mini DIN cable) is transmitted properly because the satellites are working. (The same signal is used to control the power amp for the Sub loudspeaker.)

I suspect that there is a problem with one of the following components:
- Sub pre amp
- Sub power amp
- Sub loudspeaker
- Defect of an internal cable or a circuit break on an internal circuit board somewhere between the 8-pin mini DIN Input socket and the named components.


If the Subwoofer still does not emit any sound, a Yamaha service technician will have to take a closer look at the device. But since it is, as you wrote, still brand new, I recommend that you simply send the device (the GNS-MS01) back to the seller and insist on an exchange for a faultless device.


Best regards,
Chris

Chris,

He is still having problems with his external speakers and the aux out ports as well.

Hi everyone and thank you for all the replies. I have delayed responding because I was waiting for a conclusion to the matter from the shop and Yamaha Spain.

To cut a long story short, the GNS MS01 issue was confirmed by Yamaha to be a faulty unit right out of the box.

The situation with the Line Out issues is not so clear as it was suddenly it was there and I am not sure what action I took that restored it. It may or may not have been a firmware update.

Anyway, all is good on the music front now. The store which is a mega music store in Barcelona were very helpful throughout and put me in contact with a local Yamaha person who even made a house visit. All the more impressive since we live in the country half way up a Spanish mountain!

As I said, this was a contact supplied by the store. Less than impressive were the listed Yamaha contacts who never replied!

Feliz Navidad to you all.
