| Marketing Information | The Telex Models 450D and NC450D 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. The NC450D is a noise-cancelling design that makes it particularly effective for use in noisy locations and the excellent voice response characteristics make it a good choice in quiet areas as well. Design Features: 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. 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. The NC450D includes a soft rubber lip guard which assures the user of correct microphone-to-mouth positioning. |
