Exclamation Powered Mixer/PA hitting protection way too early

I have a powered mixer that hits overload protection mode way too early. Itíll peak and hit it at a regular talking volume. Rather than cut out though it majorly distorts and lowers the sound. Any idea how to fix it? Iím on a strict budget. I do have soldering skills etc.

Cheers!

How many years old is the set? Perhaps it's calling for a recap if >10 years.

Check first if there is DC on the outputs, that tells You if You have a blown amp or incorrect rail voltages. Then proceed to the overload circuit troubleshooting.

I'm wondering if there's a short somewhere on the output and it's going into over-current limiting.

+1 for wrong impedance load, including shorted speaker wiring.
