Jim: Its very mildly cardioid then! :) This aint no shotgun, Jim!
I choose not to compensate for the boominess with EQ and not eat this mic like an HC4 as it adds to the distortion I hear in the monitor and see on the scope. I would rather run the mic gain a little hotter and put up with the room tone than deal with the boominess electronically. I can always gate the room tone. I have always tried not to "fix stuff in the mix" but I'm severely crippled with a very poor operating environment for sound. Then again, this is Ham Radio, not work! And with 12 volt finals, I need all the signal cleanliness I can get :) Of course, you are right, but I'm walking a fine line between distortion and punch. I find the fatter foam windscreen from an Audio Technica Pro8HEx mic helps me place the CM-500 capsule at just the right distance from my mouth for me. -lu- Message: 27 Date: Tue, 05 Oct 2010 14:25:59 -0700 From: Jim Brown <[email protected]> Subject: Re: [Elecraft] SSB transmit audio - Where's the punch?

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 No virus found in this outgoing message Checked by PC Tools AntiVirus (6.1.0.25 - 6.14880). http://www.pctools.com/free-antivirus/ ______________________________________________________________ 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
