Avoid running audio cables or placing audio equip- ment, close to thyristor dimmer units or power cables.

Noise immunity is improved significantly by the use of low impedance sources, such as good quality profes- sional microphones or the outputs from most modern audio equipment. Avoid cheaper high impedance mi- crophones, which may suffer from interference over long cable runs, even with well-made cables.

Fault Finding Guide Repairing a sound mixing console requires specialist skills, but basic Fault Finding is within the scope of any user if a few basic rules are followed.

Get to know the Block Diagram of your console (see inside rear cover)

Get to know what each component in the system is supposed to do.

Learn where to look for common trouble spots.

The Block Diagram is a representative sketch of all the components of the console, showing how they con- nect together and how the signal flows through the system. Once you have become familiar with the vari- ous component blocks you will find the Block Diagram quite easy to follow and you will have gained a valu- able understanding of the internal structure of the console.

Each Component has a specific function and only by getting to know what each part is supposed to do will you be able to tell if there is a genuine fault! Many ‘faults’ are the result of incorrect connection or control settings which may have been overlooked.

Basic Troubleshooting is a process of applying logical thought to the signal path through the console and tracking down the problem by elimination.

Swap input connections to check that 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 are known to be working.
