Bose S1 hum/hiss noise

Hi all,

 

Recently, my Bose S1 pro has been making a hum/hiss noise about 10 seconds after I turn it on. The noise increases when I turn up the volume on input 1 and 2 even when it’s not plugged in. The hum/hiss is there when music is playing. 
I think it started after I charged up the battery to full. I have tried having it plugged in but still makes the sound. 

Any help/people who have experienced these issues is massively appreciated.

Thanks.

Re: Bose S1 hum/hiss noise

Hi Stanley,

Welcome to the Bose forum! Thanks for stopping by. 

Please could you confirm whether the sound you hear is more like a hiss, or more of an electrical 'hum'? 

 

Also, does this still occur if the battery is removed completely?

Re: Bose S1 hum/hiss noise

Hi Dylan,

 

Thanks for your reply. It is more like a hiss than a hum to be honest.

I have not tried to take the battery out but will let you know if the sounds continues when the battery is removed. 

Thanks again,

Ant
