Communications quality noise cancelling ‘lip’ microphone, for applications where broadcast quality is not required. Typically this would include commentary work for telephone services (UK 0898 system) or for PA systems using restricted bandwidth loudspeakers such as re-entrant horns. It also has applications for intercom and other specialised paging work.
Construction is similar in principle to the 4104, though the design of the microphone head is slightly different. The lip bar feature is retained. Frequency response is 80-8000Hz, and substantially flat 200-6000Hz, with a small presence boost at around 5000Hz; other details are as for the 4104.
