MICROPHONE CONNECTING DEVICE

摘要

A microphone amplifier unit, to which a microphone of a first form including an LED or a microphone of a second form without including an LED is connected, includes a microphone detecting unit that detects a connection state of the microphone of the first form or the second form based on potential information supplied to a specific terminal pin of a connector. In the microphone amplifier unit, appropriate circuit setting corresponding to functions of the respective microphones is made based on information obtained by the microphone detecting unit. With the configuration, a microphone connecting device that can commonly use the microphone of the first form and the microphone of the second form with a small number of pins is provided.
