I hope this is the right forum for this, pre-amp schematic?

Prismatic · 24th April 2006, 10:18 AM

Ok, so hopefully this is the right forum, seems appropriate, maybe not, if not, i'm sorry...

So I want to try and build a pre-amp for my microphone (Binaural, so.. stereo signal). I was looking around the net for the simplest one and came across this:

That appears to be the simplest version I could find for a mic preamp.

I have a couple questions, though. Im assuming this wont handle a stereo signal, and if so, what might need to be changed to handle a stereo signal? And two, (I'm really noob, so excuse me) Where would I connect the leads for the power? heh, was hoping to maybe run this off a 9v battery

Thanks in advance

Excuse me, but you must have forget some central. You can't amplify without any active parts or energy.

Hmm, so that isn't the gist of the circut? Darn =/ Any recommendations on an easy to build 9v battery powerd stereo preamp? heh

Presumably that's a feedback network to connect to a preamp?, to set the gain at 33dB - but the main part of the circuit is missing.

No simple ways to boost my mic signal to line level?

the simple way is to build a mic preamp

Well thats what I want to do, just cant find a good schematic for me to try out

(Im new to that also, I can solder, just never really made a circuit before heh)

Edit - How about this? http://www.ee.washington.edu/circuit...uits/Micro.GIF
