Mic cable question

[Ptownkid]

I built a cable using some star quad recently and it's acting funny.

It is a lot quiter than my other cables and it feeds back a ton when I boost the gain to compensate, any ideas?

Star cable if wired correctly will always be quiter in noise floor. it's the twisted pairs inside that shield better against RF noise. assuming your mic is working properly, I suspect you have your cable wired incorrectly which is why it is much quiter(volume) or you have a broken conductor somewhere in the cable.. Two conductors should be at the hot. Two at the cold and then the ground. AS for the feedback part that is due to putting the gain all the way up on your mic pre. I suggest re soldering all your connections as a start. If that doesn't work look for a part in the wire that looks like it has been crimped or something to that effect. It's possible someone closed something or dropped something on it and severed one of the conductors.

Yeah, that's what i figured.

I'm sure it's wired and soldered correctly...

I'll try again.

Thanks for the reply

You got a test meter?

sorry to hijack but how is quad cable wired exactly?

pretty simple. just a pair of two:

oh ok, so the + signal is on one half of each twisted pair and the - signal is on the other..

thanks!

you could be a real masochist and do white/blue, white/blue. Someone once left cables here that were wired like that, I could never understand what must have been going through the dudes head when he made them up like that.

That'd be a bitch eh?

Yeah, I tested it with a meter and it was fine, so i redid one end and it's aok
