Brian, I can't recommend a specific model, but aside from a single quality rating, microphones differ in their pattern, sensitivity, and noise cancelling characteristics. Those differences change the best position of the mic in relation to the caller's mouth. A mic the caller isn't used to may not help. As a general suggestion, a somewhat directional pattern like cardioid and noise cancelling will cut instruments and speaker feedback. Common problems with intelligibility are level relative to the music, and room resonances. I've heard some pretty high pitched women's voices come across as boomy (and thus hard to understand) because of room response. The place to fix that is with equalization at the mixer board. There are microphones with narrow frequency response specifically for speech communication (as opposed to singing). I don't think I've seen one at a dance, and I think they use different connectors (adaptable though) than the usual XLR you see in stage equipment, and again, the same effect could be made at the mixing board. -Don On Wed, Jan 23, 2013 at 12:30 PM, Brian Appleberry <brianappleberry(a)yahoo.com> wrote:
