Lost main output channel

Post by Ultrakeys »

Anybody else had an issue with a lost main output channel? Whilst I can route to the individual outputs I lose the main volume control, which I have routed to the sliders but it’s a pain. Anybody know of a fix or is it a visit to the synth doctor?!

Manny years ago I lost an output after strange connections to a poorly grounded stage. Also on my Kronos 1. I replace the entire output board from our KORG service but I think you should replace the mute transistor on the L/R Circuit. Hope to not lost the A/D converter. These problems appear when there is a ground potential difference between two power supply sockets. I recommend to plug the output cables before the power AC cable.
