The Astatic 651 is a small-format squeeze-to-talk, dynamic microphone for critical communications applications. The omnidirectional 651 mic has a tailored frequency response providing clear transmission and maximum intelligibility of speech. The microphone's housing is built to withstand rough mechanical impact while the transducer resists atmospheric extremes. The 651 microphone has a simple-to-operate DPDT long-life, trouble-free, leaf switch. It has a low-impedance output and is factory wired normally open. The 651 mic may be rewired in the field if a line shorting function is desired.

The Astatic 651 mic is an excellent choice for any application requiring a small-format palm-held microphone for discrete or tight mounting spaces such as life-safety systems or paging stations where small size is required. The 651 microphone is also suited to most public address and general, multiple-use, commercial paging applications such as factories, airports, lobbies, restaurants, warehouses, etc.

  • For commercial public-address and paging applications as well as security, emergency and life safety
  • Small size for inclusion into life-safety systems or other paging stations where small size is indicated
  • Omnidirectional for forgiving pick-up of users that may not be committed to the mic
