The 4115 Noise Canceling Ribbon Microphone from Coles is designed to deliver audible, crystal-clear speech in high noise environments such as warehouses, aircraft, sawmills, power stations, and more. The 4115 features a highly sensitive ribbon transducer optimized for close talking. Its high directivity yields impressive noise cancellation and relative immunity to handling noises and mechanical shocks. The 4115 features a lip bar for up-close speech. The microphone includes a cable with an XLR output connection, and rigid protective storage case.
