Telex 450D Dynamic Low Z Push-to-Talk Handheld Paging Microphone

The Telex Models 450D Dynamic Microphones are designed for voice-paging applications requiring a rugged hand-held microphone.

The 450D is a low-impedance, balanced-line dynamic microphone that provides smooth, peak-free response and trouble-free performance. The rugged design makes it particularly effective for use in busy environments (e.g. manufacturing and restaurants) where excellent voice response characteristics in a microphone are required.

Design Features
The 450D features a standard omnidirectional shock-mounted dynamic cartridge. Output impedance on both models is 200 ohms for matching low impedance input circuits. A push-to-talk switch is located on the microphone housing. The black microphone housings are constructed of molded ABS plastic, which will withstand the day-to-day abuse of hand-held mobile microphone applications.

Note:
Always talk close to the microphone, with the edge of the lip guard just touching the upper lip. This is important because the noise-canceling feature accepts close sounds best and discriminates against sounds greater than 1/2-inch (12mm) away.

The coil units are equipped with an unterminated black neoprene coil cord which is relieved at the housing by a spring-type strain relief. In addition, the microphones are equipped with a hanger button, and supplied with standard dashboard mounting bracket and hardware.
