Clip microphone is a relatively low cost option for miking the presenter. The microphone should be clipped to the clothing close to the neck such as the lapel or tie. The user must try to face the same direction when speaking as a change in mic to mouth distance can affect the resulting volume even though all our amplifiers feature our unique dual action AGC which provides some degree of compensation. In situations where the background noise is high, a more closely coupled microphone to the speaker’s mouth such as a head set microphone is required.
