MICIN is the microphone input signal interface. On the sound card of a computer, there are generally two interfaces: Line in and Micin. Line in is the linear input; Micin is the microphone input signal interface, which can also be called microphone input.

Line in interface: This port is mainly used to connect the audio signal output recording of external devices such as electric guitars, electronic keyboards, synthesizers, etc. Since the output power of these devices themselves is relatively large, they need to be connected to the Line in port. Recording, of course, using them to record can also be called "internal recording" of external devices to a certain extent. Generally, the better the sound card you use, the lower the noise in Line in will be and the better the recording effect will be.

Mic in interface: This is used to connect a microphone for recording. But the difference between this port and Line in is that it has a preamplifier. In other words, the output power of the microphone itself is small, so an external amplifying device must be used to amplify the audio signal. This port serves this purpose. Friends who are interested can try connecting your microphone directly to the Line in port to record... There is no sound or the sound is very small, right? ! The reason is simple. If the microphone signal is not amplified, the natural effect will not be good.
