Q:
How do I avoid crosstalk over long
runs? |
A:
Crosstalk can occur between 2 channels over long runs.
To avoid crosstalk, where possible, avoid STARQUAD cable wired for balanced
lines.
The recommended cable is Belden 8723 for long runs. This a twin pair,
shielded 22AWG cable. However this cable does not like sun or rain and
personally I think expensive!
For more info visit Belden's
Website
Alternatives listed here are 88723, 87723 7 82723
The RECOMMENDED WIRING for twin pair and screen cable
is
XLR
Pin 1 = Screen / one leg of pair / one leg of pair 2
Pin 2 = the other leg of pair 1
Pin 3 = the other leg of pair 2
If you are suffering major problems of crosstalk and you are limited by
your cabling one tip is... having identified the line causing the most
problem:
- Insert one end of an XLR "Y" chord at the near end (from the PSU)
- Lift pin 3 on one XLR connector and pin 2 on the remaining XLR connector.
- These should now be plugged into 2 separate cables going to the far
end.
- Another normal XLR Y chord should now be plugged in at the far end.
- This will recombine the channels into the beltpack... Hopefully minus
the xtalk
