Noise Canceling Microphone


     The Road-King 56 (RK-56) Dynamic Microphone is designed for voice communications applications requiring a rugged, hand-held microphone. Its noise-canceling design makes it particularly effective for use in noisy locations, and its excellent voice response characteristics make it a good choice in quiet areas as well.

     The RK-56 uses dynamic, differential type cartridge which discriminates against sounds greater than -inch (12 mm) away. A non-marking lip guard assures the user of correct microphone-to-mouth positioning. Best noise cancellation is achieved with the edge of the lip guard just touching the upper lip. The push-to talk switch is located on the top of the microphone housing. The RK-56 is equipped with the  Highest Quality, "BELDEN" six-conductor, receive coiled cord which is relieved at the microphone housing by a telephone type strain relief grommet. The cord may be wired for either relay or electronic switching.

This is a noise canceling microphone:
Don't forget the lip guard is there to remind you of the
close spacing required. To best describe the spacing,I would say your upper lip touches the rubber guard and bottom lip should almost drag the screen when talking. Take this mic away even 1" or tilt sideways from your mouth and 70% of your audio is GONE !!!


See this video on how to properly
hold this NOISE canceling mic.
