The BCM 705 is a cost effective microphone for broadcast and podcast applications. Its entire construction is functionally optimized to convey emotion with technical perfection. Its dynamic capsule is voiced for a smooth yet clear sound with excellent speech intelligibility. The hypercardioid pattern along with the internal shock mount and pop filter minimize extraneous noises.
Broadcast and streaming are much more immediate ways to reach your audience than studio recording. That’s why we decided to develop a line of microphones that specifically addresses the needs and working conditions of radio DJs, podcast and talk show hosts, announcers, newscasters, and all those who guide us through the day with their stories, good vibes, and the latest information.
The BCM 705 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 microphone mount and a newly designed internal capsule suspension, the BCM 705 is doubly protected against rumble. An internal foam screen protects the capsule from “pops” as well as dirt, moisture and nicotine. For increased hygiene, the headgrille twists off easily for quick cleaning.
While its sibling, the red badged BCM 104, is a condenser microphone, the BCM 705 is a dynamic microphone with a moving coil capsule, indicated by a green Neumann logo. Dynamic capsules are quite sturdy, and while they sound less natural than condenser transducers, carefully designed specimens – such as this – exhibit a distinctive appeal which has become associated with “the sound of FM”, especially in the United States with its long standing tradition of private radio.
The BCM 705 is particularly well suited for local radio stations and small studios as well as demanding streaming and podcast applications. Its hypercardioid pattern and close-speech optimized capsule help to keep extraneous noises off the air, even if the sound-proofing is less than perfect. The BCM 705’s frequency response is specifically tailored for the human voice. A gentle presence boost above 2 kHz enhances speech intelligibility, while a soft bass roll-off compensates for the proximity effect, creating a low-end which is full but never boomy. The BCM 705 does not require phantom power and is extremely easy to setup: Simply connect it to a microphone input, and you’re ready go on air!
Although the BCM 705 is primarily designed for speech applications in broadcast and podcast environments, it wouldn’t be a Neumann microphone, if it couldn’t be used in the recording studio, too. Being a dynamic microphone, the BCM 705 can handle high SPLs with ease, which makes it an excellent choice for screaming vocalists, bright brass instruments, and loud guitar cabinets.
The Neumann BCM series also includes a variant with a condenser capsule: the BCM 104

"Probably no other manufacturer has so thoroughly considered the details of microphones for radio announcers. The result is a mic which is very convenient to use, with ingenious maintenance and servicing features ... Altogether, these details will enhance the pleasure of working `on air´."
