Neumann BCM 705 Hypercardioid Dynamic Microphone

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.

The BCM 705 is a dynamic microphone with a moving coil capsule. Though dynamic mics sound less natural than condenser transducers, dynamic mics in this class exhibit a distinctive appeal which has become associated with “the sound of FM”, especially in the United States. 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 and moisture.

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. 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.

Although the BCM 705 is primarily designed for speech applications in broadcast and podcast environments, it can handle high SPLs with ease, which makes it an excellent choice for screaming vocalists, bright brass instruments, and loud guitar cabinets.
