Description
Neumann BCM 104 Broadcast Microphone
The BCM 104 is a dedicated broadcast microphone for radio announcers and DJs, designed to convey emotion with Neumann perfection. Its functionally optimized design features an integrated pop screen and a shock protected large diaphragm condenser capsule, specially developed for speech. Transformerless circuitry ensures a direct, noise-free sound.
The BCM 104 has a fixed cardioid pattern with excellent rejection of rearward sound. Its frequency response is very linear with a gentle presence boost around 4 kHz and a slight treble lift above 10 kHz for enhanced speech intelligibility. Due to its outstanding transient response, the BCM 104 captures each nuance of the human voice with stunning detail. Because of its wide frequency response, the BCM 104 can be used for much more than speech applications, e.g. sung vocals and a wide variety of instruments.
- Functionally optimized design
- Specially designed large diaphragm condenser capsule
- Tight cardioid pattern
- Integrated pop screen and shock mount
- Headgrille twists off easily for quick cleaning
- Internal pad and low cut switches
