The RoadKing RK56CHSS dynamic microphone is built for voice communication environments where durability and consistent performance are required. Its handheld design is suited for daily use in mobile radio setups, particularly in trucking and CB radio applications where reliability is important.
The noise canceling dynamic element helps reduce background interference, allowing voice audio to remain clear in high-noise settings such as vehicle cabs, while still maintaining solid voice response in quieter environments. The microphone operates with a frequency response of 100Hz to 8kHz, providing balanced audio reproduction for standard CB communication.
It features an output impedance of 2000 ohms, making it compatible with radio inputs ranging from 600 to 5000 ohms. Output levels are rated at -72dB open circuit at 1kHz and -55dB power level, supporting consistent signal transmission during normal operation.
The microphone includes a 4-pin connector and a 6-conductor chrome cord for dependable connectivity. A two-position momentary slide switch with normally open contacts allows straightforward transmit control. The chrome case adds durability for regular handling and long-term use in demanding conditions.
