"Seeing your work makes me appreciate the difference between a 'real' mic tech like you and a guy like myself who just enjoys tinkering with the damn things....kinda like a shade-tree mechanic replacing oil and spark-plugs vs. the lead technician for a NASCAR or INDY champ!" — James T, Winter Springs, FL
I just wanted to mention a very good guy who just came through for me in a big way...he's Greg Heumann of www.blowsmeaway.com...my dilema was that I had a Samson wireless unit with the snap-in AX1 (not 1/4" guitar bug) low impedence transmitter. I contacted Greg and asked him if it would be possible to build me an adapter with both an impedance matching transformer and a volume control that would allow me to use my high impedence mics with xlr connectors with the low impedence snap-in Samson AX1 transmitter. He said no problem and in a matter of days it was in my mailbox. I connected it and it worked beautifully. I couldnt be happier. it also meant that I didnt need to shell out $169.00 for a transmitter that would allow me to use my bullet mics, but only useful on one frequency. Since my new transformer is not frequency dependent it has manymore uses as well which to me is an added bonus. Posted by Harpo on HarpTalk, 5-21-08
Here's a simple, but very commonly requested modification - replacing a built in cable like this Shure 520D had with a Switchcraft connector. Although this seems like a simple mod, in fact it is not as straightforward as you might think.
The 2501MP connector was designed as a "panel mount" device. It comes with threads and a raised knurled portion on the part you can't see in this picture. The knurled part is for use when the connecter is pressed in to a properly sized hole. But the shape of a mic shell makes it very difficult to support while pressing the part in properly, so most pros turn or grind the knurled part off. However the hole in the mic is usually still too deep to get a nut on the inside, so it must be drilled and tapped with the proper threads. The connector is then threaded in and secured with Loctite.
Then there's the matter of a ground connection. You have to electrically connect the shell to the ground side of the mic element. The 2501MP comes with a solder lug but this won't work if you can't get a nut on inside the shell. In that case you have to drill and tap a small hole somewhere, crimp/solder a lug on the ground wire and anchor it there.
There's no rocket science to this stuff, but the investment in proper tools and some experience are why folks sometimes pay people like me to perform this service for them. I have several thousand dollars invested in my shop tools, including a lathe and milling machine, electronic test equipment, temperature controlled soldering station, arbor press, and many custom jigs for holding/fabricating/assembling.
The pictures below show some "before and after" conversions. Both of these required precision machined threaded inserts to mate the Switchcraft connector to the original socket housing. In addition internal modifications were required to support a grounding connector.
I love a challenge. Half the fun for me is figuring out how to do what you want to do. I have satisfied hundreds of customers. Got an idea? Email me. I'm happy to discuss it. If I can't solve your problem I won't charge you a dime.
