The C 400 BL is the first choice for any application calling for a small, low-profile boundary layer microphone. Its uses range from conferencing and lectures to theaters, surveillance, paging, and many others. Its frequency response has been optimized for speech pickup.
Its hypercardioid polar pattern, speech optimized frequency response, and extremely small dimensions have made the C 400 BL extremely popular. The design is inconspicuous and the housing can be painted easily in any color to make it almost invisible against its backing.
