technical advice on long XLR cables...

["mvanoncini" mvanoncini]

Hello all,

this is my first post, so... hello everybody!

I'm looking for some advice on long microphone cables (50m or so...), I won=
der if anybody on this forum has some experience on this topic?
I'd like to connect 2 dpa4060  or a rode ntg2 to a Fostex FR2-LE, leaving t=
he microphones at a distance.
So, my questions for the moment are:

a) how do you decide if a cable is "good enough" for this application, base=
d on technical specifications?
What sort of numbers should I be looking at in terms of resistance and impe=
dence? Or is that not an issue at all?

b) does is it make sense to have an xlr to xlr connection at the middle, or=
 would that compromise sound quality?
That way I could have 2 x 50m cables instead of 1 x 100m, which would be ea=
sier to handle and would allow for 2 recording options: stereo @ 50m, or mo=
no at 100m


Thank you for all your comments...

Best wishes,
Michele
