CAD Audio 651 Small Format Omnidirectional Dynamic Palmheld Microphone with Talk Switch
The Astatic 651 is a small-format squeeze-to-talk, dynamicmicrophone for critical communications applications. The 651 has a tailoredfrequency response providing clear transmission and maximum intelligibility ofspeech. The housing is built to wIt’stand rough mechanical impact while thetransducer resists atmospheric extremes. The 651 has a simple to operate DPDTlong-life, trouble-free, leaf switch. It has a low-impedance output and isfactory wired normally open. The 651 may be rewired in the field if a line shortingfunction is desired. The Astatic 651 is an excellent choice for any applicationrequiring a small-format palmheld microphone for discrete or tight-mountingspaces such as life-safety systems or paging stations where small size isrequired. The 651 is also suited to most public address and general,multiple-use, commercial paging applications such as factories, airports,lobbies, restaurants, warehouses, etc.
Key Features
- For commercial public-address and paging applications aswell as security, emergency and life safety
- Small size for inclusion into life-safety systems or other pagingstations where small size is indicated
- Omnidirectional for forgiving pick-up of users that may notbe committed to the mic
