The BCM 104 is a dedicated Large-diaphragm broadcast microphone for radio announcers and DJs, designed to convey emotion with Neumann perfection.microphone

Neumann BCM104 large diaphragm broadcast condenser microphone is a first choice for discerning radio stations around the world.

The characteristic shape of BCM 104 is is functionally optimised for use with industry standard microphone boom arms. Thanks to its elastic mount, 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 colouration or unwanted artefacts. 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 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).

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.

If you prefer the sound of a dynamic microphone – check out BCM705.

Quick service and reasonable price. Angus was helpful and transparent.20/07/23 Update. I had an issue with some equipment that I purchased from these guys, and true to form, they were supportive and gave me consistent feedback on the progress of my concern. Elliot and Darren were incredibly committed to getting me a satisfactory result. I have recommended Factory Sound to my mates because I actually believe that they will be taken care of.

The only place to buy pro audio gear from. Been coming here for over 20 years, and a lot of the same staff still look after me. Says a lot about their business. The best service, advice and gear every single time. If they don’t have it, they’ll get it for you. No need to worry about pricing, theirs is ALWAYS the best. All the staff go out of their way to help you, and will always get back to you. Cant’ recommend this place enough, 5 stars doesn’t seem like enough.
