BK-6B
Common name: RCA BK-6B
Production Status: Discontinued / Vintage
The RCA BK-6B is a miniature omnidirectional dynamic microphone for speech pickup in televison broadcast and public address applications. Includes lanyard clip type for ease of looping around the neck. A special internal acoustic resonator is employed to support the response to lower frequencies and a damped resonator placed in front of the diaphragm reduces high frequency emphasis while extending the high frequency limit. The microphone case is rugged, weather-proof and has an integrated 30 feet, two conductor shielded cable.
