Crescendo s4

Recommended Posts

I have a crescendo s4 that after 15 mins or plat the speakers sound muffled. Amp is tuned with a dd1,  -5db @ 45 on the deck. Clean signal to 49, I don't play over 40. Amp is overheating,which is odd since it's a class d. The old class ab ( hypnotic) in the same spot could play for hours, when you touched it you could hear your fingers sizzle.  Kinda disappointed in the crescendo. Any suggestions? I sent a email to crescendo, if no resolve I will send back.

Never heard of those components either. But they look really nice. If they are a 4ohm load, i dont see why the board would be getting that hot, that fast. Bummer. Does it shut down, thermally ? or just start muffling ? Or both ? Thats a bummer. Send it back. I dont know those comp sets from adam, but, they look quite nice. Best of luck getting to where you wanna be mate. 

 

EDIT -  for fun, put a meter on the output, when its fine, take reading, then let it eat, take note with meter when it goes to shit. Just for fun.
