4104
Common name: Coles Electroacoustics 4104
Production Status: In production
The 4104 Commentator’s Noise Cancelling Ribbon Microphone is of British Broadcasting Corporation (BBC) design and used for reproducing high quality commentary speech from noisy surroundings by cancelling out a considerable degree of background noise. The 4104 is not unduly affected by wind noise and can be used in air stream velocities up to 20 mph (32 kmh) without notable difference in speech quality. Importantly the polar response is effectively bi-directional allowing one or more commentators to make clear individual commentary close side-by-side without interference from mutual crossover talk.
