The C 4500 B-BC was developed to meet the demands associated with digital broadcasting. A cardioid front-address, large-diaphragm condenser microphone, the C 4500 B-BC is immune to electrostatic and magnetic fields and provides an extremely wide dynamic range and low self-noise. Features include a switchable 20dB pad and a switchable low-frequency roll-off (6 dB/octave below 120Hz). High SPL and low proximity effect make the C 4500 B a suitable solution for voice capture in either broadcast or recording applications such as voice-over recording. Internal shock mounting is provided. The C 4500 B-BC operates on all phantom power voltages.
