Boom Mic - Just Mic
I have designed and built a headphone adapter/transformer
for some custom-molded in-ear headphones that offer excellent noise isolation (passive). I actually use them as a musician. In the plane, they sound very nice and are quite comfortable. So - what I want is a boom mic. I've actually ordered/purchased a couple off eBay, and find that they aren't quite working right. (I haven't lost much $, though.) Can anyone point to a regular ol' boom mic (head band or holder required)? Quite frankly, I like my earphones better than 5 or 6 over-ear sets I've tried (and mine are not very cumbersome). So I'd like to just buy (used of possible - money is an issue . . .) some boom headset that has the .206/.210" connector and use the yoke PTT switch. Any help would be greatly appreciated! Thanks, Gary |

Can anyone point to a regular ol' boom mic (head band or holder required)? That's the hard part. What you don't realize is that between this "regular ol' boom mic" and the radio (generally inside the earcup of a headset or in a little box on the headset cord) is an amplifier and matching circuit to take the relatively low output of the "regular ol' boom mic" and kick it up to match a carbon mic simulation. That's the hard part. Jim |

That would imply that some DC votlage is supplied along
one of the conductors (much like Phantom Power in sound mixing consoles). Does anyone know which pin and what voltage that is at? Thanks and regards, Gary |

12v across the mic plug ( on the ring and sleeve, not the tip ).

Perfect - thanks.
I can test the set I have now in our lab. |
