This kit form B&H contains two Astatic 651 Small-Format Dynamic Palmheld Microphones.
The Astatic 651 features a small profile, making the microphone ideal for tight-mount spaces in life-safety and security systems, paging stations and more. A long-life, trouble-free leaf-switch provides quick momentary On/Off function and a four-conductor unterminated cable connects to paging systems, radio receivers, etc. The omnidirectional polar pattern provides a generous pickup area and is ideal for busy commercial use. Its rugged, black housing is ideal for rigorous use and the frequency response is tailored for speech.
