STC 4033A Microphone, 1948.
The 4033A was produced as a direct result of the needs of the 'talkies', which required a microphone that could eliminate unwanted sound from the camera and other noises. It contains two elements, a ribbon and a moving coil (similar to a 4021 minus the biscuit). The microphone incorporates a screwdriver-operated switch that allows either or both elements to be routed to the output. The switch is marked P. R. C.
