Hey,

I have a mic rated 310 ohms and a preamp that goes from
150 - 3K ohms. should i match the impedance on the preamp
to the mic? i've heard conflicting stories about that i
should match it and that i should max out the preamp
impedance.

what do you guys think? i'm not an electrical engineer,
so i don't konw.


If you want to let your ears be your guide, just make an XLR adaptor
composed of a male and female jack connected together, with a 300 ohm
resistor connected between pins 2 and 3 inside one of the connectors. It
could be as simple as a 3' XLR jumper with the resistor added. Parts cost
under $10 and all parts available at Radio Shack. Plug it in, and listen.
Plug it out and listen.


This is good technical stuff, from the great unwashed, We should all
be so-so grateful he bothers to contribute, You can't get info like
this just anywhere

We've all learned today, how to plug something in,, Then we have
to master plugging it "out" . or is that a very precise way of saying
unplug the thing.
How fortunate we all are, NOT.

He got confused the other week, got a new job as a " stop // Go "
man,
only trouble was the pressure got to him, and he said ''Go'' when he
should have said "Stop", and some lucky **** run over the prick.
