I've been looking at several cable samples (the folks at Belden are great,
BTW), and have come down to a few selections, but am now seeking a little
wisdom
I can buy Belden AES-EBU cable (1800 and 7890 series) for analog snake
use, and then also be ready to send digital data down the snake when I can
afford to put pres and converters near the stage. AES-EBU cable is a bit
more expensive, but now I'm wondering if I'd ever run AES-EBU for
long haul data, or whether I'd wind up using something else, like the
appropriate baluns and a Cat6 snake of some type.
The AES-EBU cable is 13 pf/ft; the standard analog stuff (1900 series) is
26 pf. Others have posted that 26 pf/ft should not be an audible issue for
at least 600 ft. It'd be rare that I'm over 400 ft for the kind of venues
I'll be in (medium to small halls; no arenas). I also wonder if the higher
capacitance might help a little with RF immunity (short of going to star
quad which, at nearly 40 pf/ft, would probably be too reactive at those
lengths).
So, for the lower capacitance should I lean toward AES-EBU whether I ever
send digital or not, or stick with the regular analog stuff?
The other question is size: for mic runs under, say, 500 ft, do I gain
much by going to 24 gauge v. 26? That 24 gauge 180x series is big stuff;
even with an 8 channel might become a mechanical issue (rolling,
transporting, etc).
Thanks in advance,
Frank
