The NC450D Dynamic Low-Z Handheld Microphone from Telex is a voice-paging, noise-canceling mic that's suitable for use in noisy locations. The voice response characteristics make it a good choice in quiet areas as well.
The NC450D microphone contains a shock-mounted dynamic, differential type cartridge, which discriminates and cancels distant sounds and noise in favor of voice inputs spoken close to the microphone. Output impedance is 200 ohms for matching low impedance input circuits. A push-to-talk switch is located on the microphone housing.
The black microphone housing is constructed of molded ABS plastic, which is engineered to withstand the day-to-day abuse of hand-held mobile microphone
applications. The NC450D includes a soft rubber lip guard which assists the user in employing correct microphone-to-mouth positioning.
