monradon Posted June 14, 2007 Report Share Posted June 14, 2007 Is a battery box , power for powered mics ??? If so do you have to worry about overloading the mic. input ??? I am looking for a new mic for my sharp mdmt 15 and was looking at a audio technica pro 24 battery powered stereo mic. is this too much for my sharp or is there something better ???? I am not looking to record stealth just at jams and outdoors often . Quote Link to comment Share on other sites More sharing options...

I am not looking to record stealth just at jams and outdoors often .A battery box is a box, usually plastic, with a simple circuit and a battery. Its purpose is to supply bias current to electret condensor mics. The voltage supplied by the mic-in of most MD's is not that high. With the voltage supplied by the battery box you can record at higher volumes (SPL's) without having the mics distort. It is not a 100% guarantee against distortion, but it helps a lot.This board has an excellent post by Greenmachine on how to build this box. You can also buy one for ~US$50. The AT Pro 24 is just the type of mic which would profit from a BB. You may be better off spending about twice that at Sound Professionals and getting the AT-U853's with the 4.7Kohm mod. Their model number at SP is SP-CMC-4U. Microphone Madness also make a nice pair of Sennheiser's, MM-HLSC-1, which is a bit more. If you do any more recording than just a few sets you may as well bite the bullet and get a set of good, mid-priced amateur grade mics.Cheers Quote Link to comment Share on other sites More sharing options...
monradon Posted June 14, 2007 Author Report Share Posted June 14, 2007 Thanks for the info but they are kind of out of my budget right now. Quote Link to comment Share on other sites More sharing options...
A440 Posted June 19, 2007 Report Share Posted June 19, 2007 Back to your original question. When you plug a mic into mic-in it sends 1.5 volts of "plug-in power" to the mic, which needs a little bit of power to run. When you use a battery box, it sends whatever its voltage is--usually 9V--which opens up the mic's dynamic range and lets it handle louder sounds. The power goes to the mic, not to the mic input. A mic turns sound into an electronic signal, so the louder the sound, the stronger the signal. When you use mic-->battery box-->line-in, you're getting power from the battery box to run the mic and a strong signal (loud sound) to register on the MD.
