The CM500 is NOT an omni-directional mic -- you've noted that it has proximity effect, and that's BECAUSE it is a cardioid (directional) mic. As to the proximity effect -- you can compensate that the same way that virtually ALL vocal mics are compensated within the mic -- with additional low end rolloff. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
