The BCM 705 is the second microphone in the new
Neumann broadcast line and the first ever Neumann dynamic microphone. It
utilizes a Neumann-redesigned version of the Profi Power Sennheiser MD 431
handheld stage microphone and capsule. Housed in the same body as the
previously introduced BCM 104, the BCM 705 is immediately identifiable as a
Neumann dynamic microphone by its new 'green' Neumann badge.
For the BCM 705 a major overhaul of the production steps of the original MD
431's capsule was required. This was necessary to reduce tolerances in both
frequency response and sensitivity to meet the application specifications
for this new microphone.
To enhance low frequencies, the entire chamber surrounding the capsule in
the BCM 705 is enlarged and acoustically coupled to a rear entrance port.
Even though the BCM 705 is meant for close talking, there is relatively
little low-frequency build-up due to the proximity effect. This makes the
microphone a perfect choice for talent who would prefer to work slightly
further from the mic away yet maintain a good, solid bass response.
The same wire mesh pop screen principles used in the KMS 105 and BCM 104
microphones are utilized in the BCM 705 thus removing the need of foam in
front of the capsule as originally used in the MD 431. Resistance to wind
plosives was now improved. The integrated pop screen can be removed for
cleaning without the use of tools and like the BCM 104, individual,
color-coded head grilles are available for each user.
Finally, Neumann redesigned the capsule's mechanical suspension to reduce
the mic's sensitivity to stand movement or handling shocks. The microphone
in its mount is elastically suspended and compatible via standard
broadcast-segment microphone arms.
