This is for the SXA 180. That's all i could find.
Edit: Looking at it. I've seen this exact class D Amp schematic before in HK and JBL subwoofers. Is Electro Voice related to HK? Of is this some standard module manufacturers buy?Last edited by proditaki; 09-18-2023, 04:22 AM. -

Hello everyone.
I need help with my Yamaha MSR400 - Powered PA Speaker that I bought it used recently.
It is power on, and sounding good / working perfectly fine. However after 3 - 5 minutes, the heatsink is starting to get warm, and it smells burning a little bit.
I did tried multiple times on different day, event the speaker is not playing any song (input does not connect to any source, and the volume level is zero), after it turns ON, 5 minutes later, the heatsink is starting to get warm, and it smells burning a little bit. I am afraid keeping it ON longer than 5 minutes... -
