- Images 1
The BCM705 is Neumann's first mic with a dynamic capsule. Functionally optimized design specifically for the broadcast field, featuring integrated pop protection, suppression of structure-borne noise and a hypercardioid directional characteristic.
- • Dynamic capsule
• Hypercardioid directional characteristic
• Integrated, neutral pop protection
• Integrated elastic suspension
• Individual headgrilles for different users
• Colored rings to identify the replacement headgrilles
• Easy removal and cleaning of microphone headgrille (with bayonet mount)
• Mechanical compatibility with standard studio boom arms
• Multi-level isolation from structure-borne noise
• No power supply required
The BCM 705 is Neumann’s first dynamic microphone. 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. In front of the capsule, mounted on a frame holder, a fine gauze serves as a built-in popscreen.
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
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 pop screen can be removed for cleaning without the use of tools.
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.
