QR Code Link to This Post
The Astatic 651 is a small-format squeeze-to-talk, dynamic microphone for critical communications applications. The 651 has a tailored frequency response providing clear transmission and maximum intelligibility of speech. The housing is built to withstand rough mechanical impact while the transducer resists atmospheric extremes. The 651 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 may be rewired in the field if a line shorting function is desired.
