What makes a audio lead dirty?
« on: April 22, 2013, 09:18:44 AM »

Hey all.

Just wondering what makes a audio lead dirty, and I don't mean rolling it in random crap on the ground.

By dirty I mean I have a couple of cables that have perfectly clean and good solder joints at the connectors and comes up fine on my cable tester yet it does t actually worked when plugged into anything

Could it be from the manufacturing process or something?

Plus if there's any way to actually save them and get them working again then please let me know as I have a few 30ft+ cables that I would like to try and save.

This is a conflicting statement.  Your cable tester is 'something' . If the cable works in the tester then it should work in another functioning piece of equipment.  Or maybe your cable tester is broken, or perhaps you don't know how to use it.

Cable testers are imperfect while generally they will reveal obvious flaws.

Subtle connection issues may be under reported by a tester if mechanically different than mating connectors in the gear the cable is used with.

It's always something.

Are you testing for continuity and just a simple beep or are you checking for actual numbers on a multi meter?

might be a problem with the shield. I had a mic cable that would crackle if you stepped on it. Found a bubble in the insulation on one of the conductors.

It's just a simple tester which tests for continuity by showing two LEDs per pin.

Although I haven't tried using a multiple meter on it yet.

all that does is tell you if there is a short or ground. It does not in any way test the shielding. The best thing is to try another lead and see if the problem goes away. If it does, replace the cable.

Also check for shorts between pins.  I found 2 brand new cables built with 1 & 3 connected together.  I don't want to say the manufacturers name but it begins with ho and ends with sa.  :-)

When I find bad cables I shine them up with armor all and sell them to local DJs.  Yes, I am kidding.

Sometime I see mic cables that have such poor grade wire/insulation that while they can be fixed I would refuse to do so knowing they shortly would not stay fixed.
