Neumann BCM 104 Microphone – Black

Overview
The Neumann BCM 104 is a next generation broadcast microphone designed to deliver emotion with perfection. Its functionally optimized design includes features such as an integrated pop screen, shock protected large diaphragm condenser capsule, and transformerless circuitry for a direct, noise-free sound. This microphone is specifically designed for radio, streaming, and podcast use, and is perfect for DJs, announcers, newscasters, and talk show hosts who want to reach their listeners in the most immediate and effective way.

The BCM 104 is built to capture the nuances of the human voice without any coloration or unwanted artifacts. Its frequency response is very linear with a gentle presence boost and slight treble lift for enhanced speech intelligibility. With its sleek and elegant design, the BCM 104 is not only functional, but also visually appealing. It is available in both matte black and nickel matte finishes, and also has a variant with a dynamic capsule, the BCM 705, for even more versatility.

About the Neumann BCM 104 Microphone – Black
Next Generation Broadcast Microphone

The BCM 104 is a dedicated broadcast microphone for radio, streaming and podcast, 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, live streaming and podcast are the most immediate ways to reach your listeners. That’s why Neumann decided to develop the BCM line to specifically address the requirements of radio DJs, announcers, newscasters, talk show hosts, podcasters and all those who guide us through the day with their stories, good vibes, and the latest information.

The BCM 104 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 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 BCM 104 captures each nuance of your voice without coloration or unwanted artifacts. The BCM 104’s electronic circuit ensures 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 is 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 pre-attenuation to reduce the 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 pre-attenuation options are usually selected only once, at setup.

Designed For The Human Voice

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.

With its unobtrusive yet elegant styling, the matte black version (Black Edition) exudes confident understatement. Alternatively, the BCM 104 is also available in a nickel matte finish.

The Neumann BCM series also includes a variant with a dynamic capsule, the BCM 705.
