C 4500B-BC
Condenser Broadcast/Voice-Over Microphone
Description
AKG’s new C 4500 B-BC is designed for all broadcast and
voice-over applications and is ideal for the new age of digital
broadcasting. 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.
