oh, so you unbraid with this miniature cutter right?

cause it was sounding like you weren't connecting the shields.

no matter what cable you make, unbalanced, semi-balanced (or whatever you call it), or true balanced, you will always need to connect the shield to at least one end. otherwise it doesn't do anything. just making sure...

Have you heard of using a 150 Ohm resistor to connect the shield to ground? If so does it make an audible difference?

actually, no i haven't... is that the trend now?

what's the theory behind it?

I don't know where I read it but I think that perhaps it prohibits the ground signal from interfering with anything that the shielding picks up???

If someone knows something about this, I would like to know if it works or if it is just a gimmick.

well, i think it's safe to assume it's a gimmick... as you know, many companies even use more expensive copper shields, just for the fact that there's less resistance. i don't see why you want to resist the shield from grounding interference.

Erm, floating one end of the shield (i.e. one end connected to ground, one end disconnected) prevents the ground return from travelling through the sheild. The shield does its job best as a shield when there is no ground current flowing through it. Usually the source end is connected to ground. Not sure if this really matters, though. Anyway, this can cause the shield to act like an antenna, so instead of disconnecting the shield from ground totally, some people put a small cap between shield and ground at the load end only (with source end connected) to block HF interference.

but what of using the resistor?--different principle from using the cap right?

Oh right... Yeah, I dunno.

NOTE: Pacific Radio Electronics has a huge inventory of cable, connectors, patchbays and other supplies for the broadcast/post production professional. Only a sampling of them are offered here.
So when i call their number, i just ask for the switchcrafts to be added to my already placed order or tell them that i will place an order and for them to add them to it? Or should i just call and ask about it?

thanks again Demolition, you saved me more money!

I hadn't heard about using a resistor, so I Googled it and found this page. They suggest a resistor between 10-100 ohms.

However, from my understanding of how ground loops work, using a 10nf capacitor (instead of a resistor) is a more common practice.

Yeah, I just call or e-mail and ask them to source some parts that I couldn't find on their site. They usually get back to me in an hour or two with a price, then ask if I want anything else. That's when I load up on the other stuff that I want.

Demolition, thanks so much! I'll shoot them an email or call as soon as i order!
