Yes, the PRO4PIP is a 10 mm electret mono mic in a parabol, connected to
one plug in power channel just as usual, then a small capacitor leading the=
AC signal (only) to the other channel via a "too small" capacitor, thereby=
limiting low frequencies.
Then you get two mono recordings, one "full range" the other base limited.
It is, as far as I understand, the only simple way to make a base filter
with plug in power. The current available isn't enough for a low-noise
transistor filter. I have though of trying a transformer input one way or
the other, but never had the time to develop it.
When one starts to think of really carefully designed voltage step-up
circuits etc, - then the whole point with Plug In Power gets lost - the low=
cost and simplicity
