RF Resistant Omni Mini-Boundary Microphones Miniature installation omnidirectional "button" style condenser boundary mics for use in teleconferencing or voice lift sound reinforcement. Also may be used in surveillance, ambient recording or audio observation applications. Improved RF immunity to greatly reduce susceptibility to radio interference from GSM based cell phones, PDA/cell phones, cell phones with walkie-talkie capability and other similar devices.
