If we want an electret condenser mic, we want to provide the (>1,5V)
power (if the mic is without a battery inside).
For a professional condenser mic (no "electret"), we need the 48V
phantom power.
In both cases the amplification.

I personally don't want a dynamic mic, because I think they don't
sound so nice.

That's the point. It is not possible that this Shure converters do what
we want. We need a "battery powerer amplifier box".

As above, I don't think this is what we need.

I soldered this one:

But as descibed in another mail, I have tested it only with cheap mic
capsules and that doesn't sound good enough to me..

Bye, Uwe.
