| 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.
