Phantom powering was first used by the telephone industry long before
TV of any sort. If the cable TV industry - hardly a bastion of good

they're the ones that are wrong.


The telephone system was based on the same battery powered model the
early telegraph lines used. In fact, the early hand crank phones used a
local dry cell battery to power the line to the operator's switchboard.
Then there were the 20 and 60 mA teletype circuits where the power to
drive the mechanical decoder was remote powered over the data lines. It
is an obvious technology, being used by quite a few fields. As usual,
some group wants to claim to be the 'One true prophet' for their phony
religion.

Indeed - and the pro audio lot certainly didn't use the name 'phantom' for
the first line powered mics. That was called AB or T power.
