Neumann BCM 104 Large Diaphragm Cardioid Condenser Broadcast Microphone

With its large-diaphragm condenser capsule and cardioid directional characteristic, the BCM104 is ideal for the faithful reproduction of speech and music. This is due, for instance, to the frequency response that is flat up to 3kHz and then gradually boosted in the higher frequencies. If required, internal switches can be employed to compensate for the proximity effect and to reduce the sensitivity by 14dB. The versatility of the BCM104 can be seen in its wide range of applications, from news, to round-table discussions, to radio plays, to musical recordings.
