Recording and live gear: connectors and faders mainly suffer from contamination and mechanical stress

Mixers, interfaces and controllers collect dust and are connected and disconnected frequently.

Avoid cables pulling on sockets, protect faders during transport and remove surface dust before it is pushed into gaps. If an input becomes intermittent, first test with a known-good cable and source.

Internal cleaning of faders and potentiometers requires suitable products and access; do not turn external maintenance into unnecessary disassembly.
