I pushed my mackie Thumps to hard and now they are only playing high frequency sound no low end at all. In the manual it says that this may occur and it is a protection feature. The manual says that if the unit heats up it may independently shut down the only the low freq amp.It also says once the unit cools down it should start working again which is has not happened days later. Mackie support was no help and unwilling to help be identify the issue.. I checked the fuse and nothing has happened. I have two of these speakers and have tested the other speaker with the current cables, I have verified the audio source isn't the issue, Please help guys I am desperate,. Basically I want to take this thing apart and troubleshoot/repair it. but have no idea what I am doing.
Thanks for the help
