Hi
I have a client with a P90 that has been using the 1/4 L+R output jack. Recently he noticed the left side was much louder than the right side when playing through his mono powered speaker, but through headphones it sounds balanced. What would cause this issue?
The right jack (next to the L+R mono jack) is a switching jack that removes the right channel from the left jack when a plug is inserted. Maybe dirty contact in switching jack?
All of the outputs including the headphones come from the same source. Some resistor dividers reduce the levels on left/right jacks.
Thank you for the prompt reply!
