PRX715

p19978

My PRX715 stops working after a few minutes of play. The LED in the front goes from blue to red; obviously no volume from the speakers when the light goes red but it works/sounds fine while the light is blue.

The fan works while the speaker sends out volume but stops when the light goes red.

I have tried both inputs and different cables.

Any advice?

It may be power safe mode.
When input signal level too low it switch to this mode.
Try compromise with sending line signal from desk and gain level on the speaker to enough loud signal
