Help with Soundcraft schematic.

[Netlist]

Hi,
I'm looking for a Soundcraft Spirit folio 10/2 schematic.
The part with the output section would be enough.
The left output works, the right one doesn't.
I already changed all kind of opamps, without result.

Thanks

Hi!

This may seem too simple but most of the time with these kind of "everything-soldrered-on-the-main-board" mixers, the XLR output connectors solders cracks under stress.
In this case, only reheating the output connectors solders will cure the problem.

Hope it will work for you!
Anyway, let us know...

Good luck

Thanks Zappa,
But this is not the problem.
All inputs work, but when send to the outputs something is missing on the right side.
The build in 1Khz oscillator is handy to trace the signal, but with those very compact double sided PCB's it's very difficult to find the problem.

Just to let you know I found the problem.
The signal passes trough the Mix Insert jack socket that had bad contacts. It should be normally closed but with the bad contact it was open.
Thanks Zappa, your idea pointed me in the right direction
