Thank you for joining the Bose Portable PA Community.
As a general question, is it normal for your S1 Pro to heat up while in use? I don't mean warm.
The units may get a little warm.
There is burning heat coming off
That doesn't sound right. Do you mean it's uncomfortable to hold your fingers on it for a few seconds?
and I just bought the System a few days ago and have only connected my guitar. The heat comes from the controllers not the battery.
Ive have bought speakers before and this usually happens after a year of use or more (speakers have amplifiers).
If the unit gets uncomfortably hot, please call Bose Support.
