    • Q:

      Audio-Technica Pro 45 very low pickup

      I have installed the Pro45 above our stage in the small hall we have in our school hoping to pickup our children when speaking. However, it picks up nothing unless you practically speak in to it from 1-2" away.

      I have a Phantom Power supply (48v) feeding it.

      Do you have any suggestions?

    • Q:

      RF interference

      Our church is about 2 miles from a strong AM radio station transmitter. We're picking up interference on this mic. We didn't get it with the previous mic or with other mics/cables in the system. Any suggestions on what we can do? Thanks
