It has a 1-in. (25-mm) diaphragm mounted internally so that the axis of maximum sensitivity is along the microphone’s physical axis, ensuring that the microphone does not impede the viewing range of the announcer. The response of the C 4500 B-BC has been tailored so that at normal operating distances the microphone will have absolutely neutral low frequency response, and at high frequencies the response is smooth and extended. An exemplary dynamic range of 137 dB will allow it to cope with virtually all announcing and postproduction speech activities. The C 4500 B-BC is complete with its own suspended shock mount and pop/wind windscreen for further isolation from the environment. Extremely high internal electrostatic and magnetic field isolation ensures that the microphone can be operated in proximity to virtually any kind of electronic equipment, new or old.
