Neumann BCM 705 Broadcast Microphone

The Neumann BCM 705 Broadcast Microphone is specifically designed for broadcast applications featuring a dynamic capsule, integrated pop protection and a hypercardioid pickup pattern.

The BCM 705 is the first Neumann microphone with a dynamic capsule. The housing and headgrille are identical to those of the BCM 104; only the green logo indicates that this is something new from Neumann.

The principle of reduction to the essentials can be seen in the dynamic capsule with a hypercardioid directional characteristic, specifically designed for speech reproduction at close range. Multi-level isolation from structure-borne noise ensures operation free of interference, even in a lively studio environment.

The microphone headgrille twists off easily for quick cleaning. Neumann offers optional, color-coded headgrilles so that, for reasons of hygiene, each announcer can use his or her individual headgrille.

The microphones of the Broadcast Line have an elastic mount against structure-borne noise, that is compatible with standard broadcast-segment microphone arms.

The frequency response has a light treble boost, in the region from 2 kHz to 9 kHz, aiding the speech intelligibility. The bass frequency response is designed to compensate for the overemphasis of the bass caused by the proximity effect.

The integrated Pop Screen not only prevents the occurrence of plosive pop noises in vocal recordings, but also efficiently prevents unwanted particles, from respiratory moisture, nicotine, to food remnants, from settling on the diaphragm.
