Handling the Output of Microphones
WHAT IS THE OUTPUT OF A MICROPHONE?
The output of a microphone may be analog or digital, and each will be applied to a corresponding analog or digital microphone input on a mixer or a camera. Alternatively a microphone output, usually analog, may be connected to a radio microphone transmitter for sending the signal to a corresponding receiver, which is connected in turn to a microphone or line-level input of a mixer or camera. All these cases are covered in this chapter.
Conventional analog microphones change or “transduce” acoustic energy into electrical energy represented as the voltage across the microphone’s output. The output usually appears between pins 2 and 3 of a three-pin ...
