COLES MICROPHONES - Lip - Commentary

These iconic designs are engineered for use in noisy environments for applications such as sports commentary.


This is a broadcast quality noise-cancelling 'lip' microphone, specifically for commentary work in environments where the level of background noise requires that the microphone be used very close to the mouth. It is a gradient ribbon unit with a high degree of acoustic damping, fitted into a special case equipped with nose and mouth breath shields. The talking distance has to be controlled accurately in order to maintain the correct frequency response (avoidance of variation of proximity effect) and this is done by positioning bars which contact the user's upper lip. Noise reduction is achieved partially through the polar response and partially through the substantial LF roll-off characteristics of the free-field response of the ribbon unit (which is optimised for a flat near-field response). The speech quality is good, mainly due to the correct balance being obtained between the nose and the mouth tones - any deficiency of the former gives a 'stuffy' and unnatural speech quality.

The breath shields are corrosion free stainless steel mesh, and the microphones incorporate a high degree of shielding against sources of electromagnetic induction, such as television monitors.

The frequency response is 60-12000Hz, and impedance 300ohms. Distortion is less than 1% at an SPL of 120dB. A 3-pin, male, XLR connector is incorporated in the base of the handle. Dimensions: 200(l) x 57(max.w) x 76(max.d). Weight 283g.

A plastic clip-on hygiene screen is available for this microphone, which can be washed and reused, or thrown away.


This is a 4104 lip microphone with press-to-talk ('PTT') switch in the handle, for occasions when a continuous commentary is not required. The switch contacts are normally closed across pins 2 and 3 of the connector to mute the output. Operating the switch un-mutes the microphone without clicks.


Communications quality, noise-cancelling 'lip' microphone, for applications where broadcast quality is not required. Typically this would include commentary work for telephone services 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.
