ABSTRACT:
The invention is directed to a microphone, particularly a microphone of the kind used in theaters or in television studios, preferably a wireless microphone. It is known to provide marking in the form of a microphone cap or a colored adhesive tape at the end of the microphone for the variously assigned individual microphones in the studios. These solutions are relatively cumbersome and are seldom very attractive in appearance. The object of the invention is to avoid the previous disadvantages by providing a microphone with a color display which is visible from the outside and which signals the ready status of the microphone, wherein a switching device is provided for switching the color of the display.
