help with canare cable

hey guys

i picked up some canare star quad cable and some neutrik liechtenstein xlr connectors to use with preamps. i just made 2, which were my first attempts and soldering since i made a couple in college. one worked right away and the other took a couple more attempts to get it to pass signal. now that both pass signal i compared them to other cables i bought and they both produce a fairly noticeable hum compared to the ones i bought which are basically silent. is this a connection issue? if so how can i go about fixing it? i checked the soldering and they all seem to have good connections to the xlrs. could it be that i didn't tie the wires together well enough?

thanks

My entire studio is wired with Canare Star Quad cable and Neutrik connectors. All custom made, by either me or a reliable source I use. Silent as a mouse. You MUST have something wrong. Do you have a multi-meter? Check for proper continuity on all pins, and make sure there are NO strands of wire touching any ground or other pins. Verify the resistance (or preferably lack there-of on all through pins and the shield.

Yeah you definitely did something wrong.

Things to check:
1- Did you overheat the pins and melt the insert.Are the pins loose?
2- As said above (no hairs touching)?
3- Are the wires cut to the right length so they don't short out when you screw the housing on?
Other than that,they should be quiet.

You mentioned its your first soldering atempt.
Maybe you are but if your not familiar with soldering plugs.
Use a desk clamp thingy or use a pair of vise grips.
If there's solder on the pins already,melt it off.

Cut the wires so there's not a lot of play, like a prong.You only need a tiny bit of wire showing at the tip.
Put a tiny bit of solder on the pins.
Put a tiny bit of solder on the wires.
Touch the wire to the pin and heat it up till it pools.
Hold it steady(3 secs) and let it set.
If you do that,your cables will be as quiet as pre fabs.
Its not rocket science.

thanks guys. i probably have the wires exposed a touch too much but it seemed that the gain on my board was way up causing the hum. i'm finishing up some more cables for comparison
