AXBT Microphone

Contributed by The BBC Collection

The AXBT was the 4th generation design of the original Marconi Type A microphone (X, B and T representing improvements) widely used by the BBC from the early 1930s onwards.

The ribbon microphone was particularly good in studio situations and the double-sided design which accepted sound from front and back but not from the side was particularly suited to voice.

It also gave the microphone its characteristic shape, which has entered popular culture as a symbolic image of broadcasting, as well as being the icon for audio in nearly all computer software.
