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.
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?
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.
