Interesting, So, given a decent mic insert the overall audio response is very much coloured by the housing of the the insert...
Close talking a mic gives a better S/N ratio, less background noise and room colouration, but yields too much bass due to proximity effect? How to overcome too much bass (besides moving further from the mic)? What effect do pop shields and the various muffs have on the sound? . I do understand and practice Tx audio EQ to restrict the Tx BW to 2.8-3kHz and attenuate useless audio below say 200Hz. for maximum communications efficiency. I'm interested in good communications microphones and technique, but not in spending, silly money (hundreds, thousands) when a decent mic insert can be had for pennies, (almost). I'm not interested in ESSB, done well or otherwise. A good clean 3KHz SSB signal stands out and is very noticeable on our bands today. There are some very knowledgeable audio and broadcast people on this list and I'm always keen to listen to their opinions. 73, F5VJC On 29 April 2014 20:53, Joe Subich, W4TV <li...@subich.com> wrote: > > On 4/29/2014 12:32 PM, Fred Jensen wrote: > > Not sure it is limited to dynamic mics. > > Proximity effect is not limited to dynamic mics.
