Emotion conveyed with technical perfection. Neumann microphones in the Broadcast range have been designed to achieve this ideal. They have been optimized for professional studios broadcast needs, and their functionally optimized design ensures that it is character microphones.

The BCM 705 is Neumann's first dynamic microphone signed. Her body and its gate are identical to those of the BCM 104 static model; only the green logo indicates that this is new for Neumann. The dynamic capsule has been designed according to a principle of reduction to the essentials; it is hypercardioid, and specifically designed for the sound of voices in close proximity. Several insulation levels compared with structure-borne noise transmitted by way ensure perfect immunity to interference even in a live studio environment.
Mechanical characteristics
The microphone grille unscrews easily for quick cleaning. Neumann offers optional color-coded grids allowing each facilitator for hygienic reasons to use its own grid. In front of the capsule, mounted on a support frame, a very fine gauze serves as a built-in anti-pop screen.

Broadcast Line range of the microphones also feature a noise-absorbing internal suspension transmitted by the foot, ensuring compatibility with microphone stands articulated specific to broadcast applications.
Acoustic characteristics
The response curve shows a slight boost in the treble, in a region of the spectrum between 2 and 9 kHz for better speech intelligibility. The response at low frequencies is optimized to avoid overemphasis serious due to the proximity effect.
Integrated pop screen
The pop screen not only serves to reduce plosives, which cause unpleasant noise when the voice recording; it prevents unwanted body - Sneeze, nicotine, water vapor breathing, food particles ... - to bind to the membrane. It is easily removed without tools for cleaning.
Mounting
The recommended use is to mount the BCM 104 or BCM 705 on one foot standard model pole studio.

A thread adapter, for screwing on different feet models is provided. To ensure effective protection against noise transmitted by the foot, the capsule and the microphone have both an elastic suspension.

The tilt head SG 5, optional, allows tilting +/- 90 degrees of the microphone.
* The design of this microphone is a registered Georg Neumann GmbH in certain countries.
