Bonding cable shields at both ends to reduce noise

Example of RF performance of capacitor-filter connectors

Many equipment designers, including some in professional audio companies, have found that radiofrequency (RF) bonding the shields of cables to chassis/frame/enclosure at both ends helps greatly with EMC Directive compliance. They have also found that it does not compromise the signal quality when the equipment is installed – despite permitting power-frequency ground loop currents (earth loops) to flow in the cable shields. Professional audio companies using this technique have found that it also saves a great deal of time during installation and commissioning.
