ArtGraphics Posted April 21, 2006 Report Share Posted April 21, 2006 (edited) I need to do a 9v Battery Box for a AT 831R Mic that only works on 9v-52v DC, 2 mA typical phantom power. Any schematics etc. from someone who has built one, or knows how to, are appreciated.AG Edited April 21, 2006 by ArtGraphics Quote Link to comment Share on other sites More sharing options...
MDfreak Posted April 21, 2006 Report Share Posted April 21, 2006 (edited) Circuit + description:http://www.mdcenter.nl/artikelen/mics/portablephantom.phpOh, I also built the circuit in a box not long ago:p.s. I used 2x 9V blocks in series to have about 18V. Otherwise you will get close to limit on which most mics don't work anymore. Also it is better to have a higher voltage when your mic has to deal with higher pressure-levels. Edited April 21, 2006 by MDfreak Quote Link to comment Share on other sites More sharing options...
ArtGraphics Posted June 5, 2006 Author Report Share Posted June 5, 2006 Thanks for that, But I will record on a Single XLR connected (AT831R) mic, not two.I plan to have a Stereo 3.5mm into the MD to avoid one silent channel and one with sound.Any info and schematics on that would be appreciated.
