Hello,
I need to record sound coming from a large space (a room) with a
microphone connected to a PC soundcard. So far the results have been
disappointing, and I've been suggested that I need to preamp the
microphone.
Can you kindly suggest a <VERY SIMPLE> circuit design (I'm a begginer)?
I don't need anything complicated, since I can sustain without problem
reasonable amounts of noise and distortion.
I built one of these once, albeit I don't remember the component values
exactly:

It was a Radio Shack dynamic, marked "600 ohms", for what that's worth.
It boosted the mic so that the sound card could "hear" it. One difference
is, I dropped RL, replaced RC with a pot, and connected CL to the pot's
wiper, then went right from CL to the sound card input.
Good Luck!
Rich
