Re: Starting out with EM172

>>>SimpleP48RCA?<<<<? and EM172:
converting EM172 .....from 2-wire to 3-wire
?- question:?
do you mean to cut?paths connecting point 1 (GND of EM172) with an original capsule aluminum case and connect the point HOT (Drain) to capsule case? If yes, I'm not for this solution. Only to get an additional 10 meters and slightly larger SPL at the expense of reducing sensitivity in comparison with? SimpleP48basic

There are a couple of mistakes & misunderstandings in his otherwise
excellent blog. I hope I've clarified most of them in my latest version of
SimpleP48.pdf in Files/Ricardo/SimpleP48
> I want to build something with the EM172s that works with 20-30m cable
runs
SimpleP48basic with EM172 is good for 20m cable.
SimpleP48RCA should do 30m.

My vote goes to Zapnsparks detailed & complete Schoeps versions in our
Files.
> Is it also possible to mount the capsules in metal bodies without the
copper tape shielding and multiple layers of heatshrink?
Your metal bodies must take the place of the Cu tape and be connected to
the shield of the cable. The bodies must be insulated from the capsules ..
which is the purpose of the 1st layer of heatshrink.
Have a look at Casey Connor's pics in SimpleP48.pdf and try to understand
what he is trying to do. The final piece of heatshrink is just to tidy
things up.
