Yes. An RE11 or RE16 is even better, because they are directional and reduce background noise pickup (fans, room noise, etc.) > To use this unbalanced you > are correct to connect pin1 to pin3 (cold to ground) Yes, Pin 3 to Pin 1 is right, but Pin 1 is the SHIELD, not "ground," and Pin One must go to the SHIELDING ENCLOSURE (the chassis) to provide shielding and prevent "the Pin One Problem." The distinction between "ground" which some interpret (wrongly) as a connection to the EARTH, and a connection to the SHIELDING ENCLOSURE is important -- no connection to the EARTH is needed to prevent noise or RFI issues. > do not connect the XLR connector body to the ground it should be left > floating. Again, this word "ground" confuses the issue. Inside the microphone, there MUST be a connection between Pin One and the metal shell of the mic -- this provides shielding for the mic itself. AES Standards also call for a connection between Pine One and the shielding enclosure INSIDE EQUIPMENT, but require that there be NO connection between the cable shield and the cable shell. There are very important reasons for this that don't matter here. :) 73, Jim Brown K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
