RK-56B Noise Canceling Microphone

More information

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 ½-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.
