I have a Yamaha EMX 512sc powered mixer that gets heavy use. Recently a new problem has arisen ... it seems like the L output is way more sensitive than the R and the limiter light for main L is flashing even at very low (below the 2 setting on the knob) levels.

It seems to be across all channels and with different inputs. The speakers have been recently tested as well and do not seem to have any of their own issues.

Has anyone else encountered this problem and could help me out?​
