Can a bad ground cause an amp to go into protect mode?
What does the protection light mean on an amp?
The BX250 and many other amplifiers use the same solid red light to indicate both that the signal is muted and that the amp is in protection mode. If your unit goes into protection mode, it is a good and bad thing- good that further damage is being prevented, but bad in that it may delay the gig.
Why does my amp go into protection mode when the bass hits?
Put simply, bass, the lower frequencies, require much more power than the high frequencies to produce equal loudness. When the bass hits, you’re asking your amp to produce more clean power than it can. So it shuts down to protect itself, and your speakers.
