Connection Cables

 

 

Take care of the connector cables, always holding them by the connectors and avoiding knots and 
twists when coiling them: This gives the advantage of increasing their life and reliability, which is always to 
your advantage. 
Periodically check that your cables are in good condition, that they are correctly wired and that all their 
contacts are in good condition: a great number of problems (faulty contacts, ground hum, discharges, 
etc.) are caused entirely by using unsuitable or faulty cables.
