The Audio-Technica AT831cW - Mini Cardioid Condenser Mic requires an unspecific amount of power from its connection to the AT UniPak transmitter or similar.

question

I need to practically swallow the 831cW for it to pick up my voice. Is there a omni-directional mic that would work better? What am I doing wrong here?
Asked by: Anonymous
We have not had that issue with our mic , it was purchased as an upgrade from the mic that came with our wireless unit. It was a big improvement . It has always been clipped on tie not the lapel. Cables are very sensitive on all units we have used so don't wrap them. A lot depends on receiver position & how much power you have for system.
