I have two custom made Canare star quad L-4E6S that I had made up years

Lift pin 1 on the XLR ends. Does the noise go away? You can use a
ground lift adaptor or you can modify the cable.

I already cut the 1/4 inch TRS connector off of both cables. :-(
I need to build another balanced cable and need the ends.

I just bought one from Markertek for the wiring job in question and I
have a bunch of TS in my possession.

I went 1/4" with inferior cable for grins and will be returning, but the
hum is much less noticeable when again cranking up the gain.

The reason why people use DI boxes on stage is that they contain
transformers that allow you to break ground connections with impunity.
You don't get QUITE as good an ability to do this just with an XLR input
that is electronically balanced, but it's not too bad.

It would help if you could show us what the actual wiring inside those
cables was.

I would like to avoid the direct box suggestion at all cost if possible
and was hoping to avoid this and as Scott brought up, yes this cable is
all I have and I have a bunch of it.

Why not the DI?

I would prefer no DIs in the studio and good ones can get expensive plus
it becomes an eyesore in my situation but thanks for asking Mike and
others just the same. :-)

If you want some cheap RG-174, give me an address and I'll send you a few
feet. It costs me pennies.

Thanks a bunch but I can afford that cable. :-)
