Old Lyme, CT (April 29, 2005)–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 “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.
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.
