Neumann BCM 104 Broadcast Microphone

The Neumann BCM 104 Broadcast Microphone is ideal for the faithful reproduction of speech and music. The versatility of the BCM 104 can be seen in its wide range of applications, from news, to round-table discussions, to radio plays, to musical recordings.

The Neumann BCM 104 Broadcast Microphone is a studio broadcast microphone with a cardioid directional characteristic. It features low self-noise with an impressive dynamic range, modern transformerless circuit technology, and extremely true, open sound reproduction free of coloration.

The Perfect Gateway to Your Listeners
The Neumann BCM 104 Broadcast Microphone 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.

You Speak – the World Listens
Broadcast is a much more immediate way to reach the listeners than studio recording. That’s why Neumann decided to develop a microphone that specifically addresses the needs and working conditions of radio DJs, announcers, newscasters, talk show hosts, and all those who guide us through the day with their stories, good vibes, and the latest information. The Neumann BCM 104 Broadcast Microphone is designed to convey emotion with perfection. Its characteristic shape is functionally optimized for use with industry standard microphone boom arms. Thanks to its elastic mount, the Neumann BCM 104 is well protected against structure borne noise. An integrated pop screen behind the headgrille protects the capsule from air blasts and plosives. For increased hygiene, the headgrille twists off easily for quick cleaning. The large diaphragm condenser capsule of the Neumann BCM 104 captures each nuance of your voice without coloration or unwanted artifacts. The Neumann BCM 104’s electronic circuit has an extremely low self-noise of only 7 dB-A and can handle enormous sound pressure levels of up to 138 dB without distortion. Its balanced output operates transformerless to ensure minimal hum interference and high common mode rejection against extraneous signals e.g. from computer screens. A subsonic filter suppresses frequencies below 20 Hz. For close speech operation, an optional 100 Hz low cut is available to compensate for the proximity effect. A second switch activates a –14 dB preattenuation to reduce the Neumann BCM 104’s output level for use with equipment designed for dynamic microphones (which typically have a much lower sensitivity than condenser microphones). Both switches are hidden inside the microphone as the low cut and preattenuation options are usually selected only once, at setup.

Designed for the Human Voice
The Neumann 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 Neumann BCM 104 captures each nuance of the human voice with stunning detail. Because of its wide frequency response, the Neumann BCM 104 can be used for much more than speech applications, e.g. sung vocals and a wide variety of instruments.
