"Dave Plowman (News)"

You'd be surprised. Some time ago I made up 100v line XLR cables using
ordinary mains 2 core flex. Cheaper than screened cable. And found one in
use with a dynamic hand mic - because it was a nice shiny white, rather
than the more usual mic cable grey or black. And apparently worked just
fine. In other words it's the balancing that gives the majority of the
rejection of spurious stuff.


** If you wire a twin shielded mic cable in unbalanced mode - there is no
problem either.

Proving beyond doubt that balancing is irrelevant to noise rejection with
mics.

However - *IF* an unshielded pair is used for a mic, balancing ( plus
good RF rejection) becomes critical to a usable result.
