hei, I have a question not directly related to PD. But since this list is my favorite audio and device-hackers list I ask it here. (maybe you can refer me to a nice list about topics like that.) I have some microphones - a very cheap small microphone and a stereo mic- they work fine to record into my mp3-player. But I want to record directly with those mics into pd trough my soundcard (audio kontrol 1). And it's not amplified. How can i build a hardware amplifier for those mics- or buy something like that? any suggestions? (I prefer to buy something- since I have to hack allready a lot of other devices...)
thanks for any hints cheers [moritz~]
sorry for the ot question --sorry when this question came twice..

A nice circuit here but you have to build it: http://books.google.ca/books?id=dunqt1rt4sAC&pg=RA5-PA424&lpg=RA5-PA... If the url is too long, google for "single supply mic amp" and look for Op Amp applications handbook - Google Books Result by Walter G. Jung - 2004 Single-Ended, Single-Supply High-Impedance Mic Preamp.

this circuit gave me decent result: http://probing.wikidot.com/electret-microphone-pre-amplifier
you can listen a recording i've made with it: http://probing.wikidot.com/local--files/electret-microphone-pre-amplifier/em...
with a very cheap electret microphone (2$). pat
thanks a lot-- It seems that I have to spend some time into this because I'm not really the circuit constructor, I'm more a circuit bendinger ;) any cheap premade preamps out there?
cheers mrz

Hi,
I actually bought a two-channel Behringer thirty-band equalizer at an antique store a few months ago. It cost me about $15AUD -- roughly the price of three beers -- and it's only four or so years old. So while it isn't specifically designed for pre-amping, it seems to do it quite well and for that price I don't think I'd find much better..
Thanks, Amos Robinson

well, your choises are huge ..
have a look on diy-audio and head-fi forums for discussions of different options ..
if it's a totaly cheap mic - you can just plug it into soundcards like soundblester ..
i myself have an alen&heath 14 desk (zed-14) .. it's good for most of the stuff i do here at the moment. i got a funny '70s AKAI mic which is good enuf to shout into and make beatbox trought pd effects that i build.
but i'm planning to get a few SM-58's and some concer mic at some point .. but now i haven't got cash for that.
you see ..i cannot recomend you a preamp to your mic cause it's to complicated to answer such question - all depends how much cash you are willing to invest ..
may be, if you are after a cheap&cheerful option you could look at some usb-mics ??
but yeah ..check out the two formus i meantioned, they are populated by loats of decent audio gear diyers ;)
also sound-on-sound magazine may be ..for reviews on new gear.
but i have a feeling that a usb-mic is the right gadgd for you!

Hi,
I use an AK1 myself. It has two inputs channels, one with a mic preamp (and also 48V) built in it.
For your "cheap mic" (mono I suppose?) it is likely that all you need is an adapter to convert it to the relevant size... 1/4inch or XLR. Pop it into input channel 1 and select the input source to "MIC" using the front button.
If your "stereo mic" is one of those that are battery operated and has 1 output connector, it is likely you will need a connector to split the output to feed the two inputs in front of the AK1.
And last, if your stereo mic is NOT battery operated, you will probably need at least one external mic preamp cause the AK1 has only one built in.
If you can send me a photo of the mic including the connectors, I maybe able to forward you to the necessary adapters.

hello, thanks for all the replies!
This won't work with the AK1, because the level of those electret-mics is to low. The mic-input in AK1 is working for other mics like dynamic mics or condensator mics. Or am i missing something? (I'm not really educated in microphonics.)
Anyway, I found now my fast workaround: -(because the performance will be in less than 2 weeks, and I have to hack telephons and a lot of other stuff)- The cheap microphon goes into my mp3-player and will be amplified there in monitor mode and goes direct into the Audio Kontrol 1.
thanks again- When I have the time I build this "amp-circuit"..

Hi,
maybe your electret mic had no power? Like other condenser mics (it's actually a kind of condenser mic) it needs to have a small power source. See following page for more info on microphone powering:
