          Excellent suppression of RF noise. Plugged the filter into the gooseneck microphone and into the mic base and the cell phone noise ceased. Placed a few more downstream as well. What a difference!

              We tried all the other fixes & nothing worked.
              These worked great on our Church Choir Mics.

                    Comments about Shure A15RF In-Line XLR RF Attenuator:

                    Had 2 ambient mics mounted high in a church. They were only being used for recording - and they were picking up an AM radio station with crystal clarity (770 AM - "News Talk Radio 77" to be exact). Only the church didn't want the radio station in the recording ...

                    I installed 1 at each microphone and the radio station went away. They worked like a charm.

                    I tried installing them downstairs at the sound system console - they did not work. I tried installing 2 in series at the console - that didn't work either. You have to install them at the microphone location (usually up high where the radio station is being picked up) - but they work really well. I recommend them highly.

                      This works. I had a pronounced RF signal coming through when using both my AKG and EV condensor mics. Tried everything else including magnetic clips on the wires. Inserted this between the connections and the noise is gone. Nice.
