Neumann BCM 705 Dynamic Small Diaphragm Broadcast Microphone Hyper-Cardioid
The Neumann BCM 705 is a small diaphragm dynamic microphone. Its polar pattern is hyper-cardioid. Emotion conveyed with technical perfection. This is the ideal which the Neumann microphones in the Broadcast Line have been designed to fulfill. The fine-tuning to the requirements of professional broadcast studios and the individual, functionally optimized design ensure that these are microphones of character. The housing and head-grille are identical to those of the BCM 104. Only the green logo indicates that this is something new from Neumann. The BCM 705 is, in fact, Neumann’s first dynamic microphone. The principle of reduction to the essentials can be seen in the dynamic capsule with a hyper-cardioid 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 head-grille twists off easily for quick cleaning. Neumann offers optional color-coded head-grilles so that, for reasons of hygiene, each announcer can use his or her individual head-grille. In front of the capsule, mounted on a frame holder, a fine gauze serves as a built-in pop-screen. 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. A 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.

The preferred mode of operation is to suspend the BCM 104 or BCM 705 from a standard studio boom arm.  A thread adapter to fit different connector threads is included. In order to provide protection from structure-borne noise, both the capsule and the microphone in its mount are elastically suspended. The optional SG 5 swivel mount allows additional angling of the microphone by +/-90 degrees.
 
The BCM 705 is the first Neumann microphone with a dynamic capsule. Functionally optimized design specifically for the broadcast field, featuring integrated pop protection, suppression of structure-borne noise and a hyper-cardioid directional characteristic.
 
Applications 
(1) Announcer's mic for broadcasting and studio.
(2) This is just one of the most common applications. We recommend additional experimentation to gain maximum use from this microphone.
