Repairing a sound mixing console requires a specialist, but basic trouble shooting is whitin the scope of any

user if a few badic rules are followed.

The Diagram is a representative sketch of all the components of the console, showing how they connect and

how the signal flows through the system. Once you have become famliar with the various components, you

can understand the internal structure of the console and you can track down problems by elimimation.

• Swap input connections to check if the source is really present. Check both Mic and Line inputs.

• Eliminate sections of the channel by using the insert point to re-route the signal to other inputs that you

know are working

• Route channels to different outputs or to auxiliary to identify problems on the master section.

• Compare a non-working channel with an adjacent channel which had been set up identically. Use PFL to

monitor the signal in each section.
