Neumann BCM 104
ABOUT THE PRODUCT
With its large-diaphragm condenser capsule and cardioid directional characteristic, the Neumann BCM 104 is ideal for the faithful reproduction of speech and music. This is due, for instance, to the frequency response that is flat up to 3 kHz and then gradually boosted in the higher frequencies. If required, internal switches can be used to compensate for the proximity effect and to reduce the sensitivity by 14 dB. The versatility of the Neumann BCM 104 can be seen in its wide range of applications, from news, to round-table discussions, to radio plays, to musical recordings.
