Re: Cardas RCA (female) mounting question...

There are many apps where you want to conrol where the input and output grounds connect to the chassis...As an example, in a power amp, currents within the metal chassis (eddy currents from the transformer, as an example), may cause the ground to vary potential. If the input sees that ground potential, you may get hum.

The isolated rca's give you flexibility in where the input ground actually connects.

Just use the right size drill. I personally like the unibits, as they have only one cutting edge, and tend not to chatter. And the next size on the shank serves as a great chamfering tool, clearing any sharp edges that could cut the plastic insulator.

Solder the ground to the ring lug OFF the mount, as you can melt it.

Where to connect the ground? That varies by circuit, you'll have to try...You've given not enough details to answer that, other than a typical star ground.

Cheers, John
