| 110629 | 2003-01-03 00:43:00 | Is there any difference between computer headset microphones and ordinary microphones used with a pa system? And why does the computer microphone have a stereo plug on the lead? I am trying to use my computer headset mic that I got with Dragon Naturally Speaking on a pa system in a tour coach. But it doesn't work. Thanks, Andrew |

If that plug is put into a mono jack, that could short out the signal, if the ground contact in the jack hits the middle contact of the plug :-( You could try a stereo-mono adapter (but try it in the shop ... if you can get a clued up assistant interested). |

| 110631 | 2003-01-03 01:10:00 | Hi Andrew: This is an interesting question, and one that is not generally understood. As you may know, the common monaural mics used for PA's & recording purposes are generally dynamic types. The typical computer mic as used for connecting to the soundcard, is very different. It is an electret mic which requires a small DC voltage to operate. This voltage is provided by the soundcard mic socket. Although the computer mic is not a stereo mic, this explains why a stereo mini plug is needed for the mic connection. The connections of this plug are: Tip: monaural audio. Ring: small DC voltage. Barrell: Earth. You will see this explains why your computer headset mic will not work for your PA system, without modification & provision of the DC volts. It also explains why it's not good practice to connect stereo lineoutput cables, or dynamic mics into the soundcard mic socket. Cheers. |

| 110633 | 2003-01-03 08:28:00 | Fine Andrew, I guess thats the best ting to do. The Electret mics are excellent quality, & are used extensively for phones, cellphones, & handsfree arrangements. For your information & other Press F1'ers, the following Shure Microphone site has information on the use of mics into soundcards. www.shure.com Cheers.. |
