Re: [Harp-L] questions re Shure 545S mic

["Ralf K. Buschner" <r_buschner@xxxxxxxxxxx>]

Hi,

you can chose the impedance by soldering the cable to the plug in different 
pins of the plug. Don't change the wiring inside the mic, you do it much, 
much easier in the 4-pin Amphenol plug, and that way you cqan change the 
impedance by using different cables. Need a Lo-Z-mic? Take this cable. A Hi-Z 
one? Take the other cable. Sounds simple, gee?
If you have the Amphenol 4-pin connector, i'll have a look inside mine and 
tell you, which pins you have to use, ok?

cu,
Ralf
