Bose 312 Sound Cuts in and out

Hi Anonymous, you are surely taking the signal for your wireless headphones, from the headphone output of your Bose sound system
This usually cuts the sound in the external speakers
Try to find another type of audio output for your headphones
Comment on what Bose system you have, so I would try to find a better solution
I hope you comment

Trata de buscar otro tipo de salida de audio para tus auriculares
Comenta que sistema Bose tienes, as? tratar?a de encontrar una mejor soluci?n

If you only pull the plug out for 5 minutes this will have nil effect as most systems have a power battery that curves up during use and keeps setting etc during power cuts so until you unplug it for at least 24 hours which is longer than most power cuts the settings put in won't change and go back to factory settings

Chances are it has what is called a cold solder connection /or the audio ic heats up and cuts out

Try the following:

1) Switch the unit off completely, using the powerswitch on the back of the bass box.
2) Switch the unit back on via de switch on the bass box.
3) The display should read BOSE 321 and than be dark.
4) Insert a CD and switch the unit on with the remote by selecting the CD/DVD mode.
5) When the sound is now OK, it means that you need to contact Bose to ask them for the latest software update for your unit. After updating your system. The problem will not reoccur.
6) in case the problem continues and at start-up using a CD, no improvement of sound is heard, the system should go into repair. Contact Bose in your country and ask for return instructions.

It sounds like you have a intermittent problem in the driver output stage, it should be exchanged for a new one, because this is a problem that can not be fixed easily.

you can try uninstalling and reinstalling the drivers,or also try to update it

It sounds like the speakers are either peaking and shutting down or they are dodgy. Check the volume going into the speakers and turn it down see if that works, otherwise take the speakers back. It might be worth trying a different set of speakers as well

What you describe, sounds like a speaker short. Are you using the Bose wiring with their ends and no cuts in the wire? (splices) It's not too uncommon to extend or shorten a wire. The fastest way to find a short is to disconnect your speakers at the speaker. Be careful to keep the wires separate if they are not on plugs and turn on. If it cuts off (power) or says (protection) on the display that lets you know your speakers are ok and you have a short in the system or a wire. Next, disconnect wires at the sub one by one and test until it causes the system to cut off or short. Leave that speaker disconnected from the sub and test with all others connected. Now you've located the channel that has the problem. First just connect the wire again to the sub. if it cuts out, run a new wire from the sub to the spkr, for testing purposes make it a short wire if possible and test. If you need to use a Bose plug at the sub to test spkrs go buy one at Bose, don't cut your factory wire just yet. If a new plug works then cut and replace. Make sure you use electrical tape not scotch tape or duct tape. If it works fine, test the new plug on the old wire and see if it works. If it does your done, if it doesn't, run a new wire to the speaker with the new plug on it. If after all this and it still doesn't work. Sounds confusing I know, It's just process of elimination, that's how we do it in the field. If all your speakers are disconnected and it still cuts out, it could be the sub or the receiver. Take it to a Bose store and they can check each piece for functionality. If it needs repaired let Bose do it. Hope this helps.

Hi, your system has some problem on the bass module which overheats the thermal sensors built in the bass module/subwoofer. I recommend that you bring the bass module to the Bose service center near your location.

That is the only solution...

Hi when you turn on check all your speakers work check connections make sure the wire has no stray strands touching the fault could be in the sub unit this is possible / or your speakers one or more could have gone short circuit due to exessive volume thats if you play loud. Had a party lately .Just joking .Regards kirk
