Mic In vs Line In: What's the Difference and Which One should You Use?

When it comes to recording sound using an input cable, you may have come across two different ports: mic in and line in. These ports are found on audio devices such as computers, amplifiers, and recording devices, and each serve a different purpose. Understanding the difference between mic in and line in can help you choose the appropriate input for your recording needs.

The main difference between mic in and line in lies in the level of the audio signal they handle. Mic in, short for microphone input, is designed to handle the relatively weak analog signals produced by microphones. Microphones generate a very low-level voltage, which is then amplified by the mic in port before it is converted into a digital signal for recording or playback.

On the other hand, line in, also known as line level input, is designed to handle much stronger analog signals. Line-level signals are typically louder and have already been pre-amplified by a mixer, amplifier, or other audio source. This means that line in ports do not require additional amplification and can connect directly to audio devices without any loss of audio quality.

So, which one should you use? The choice between mic in and line in depends on the type of audio source you are connecting. If you are using a microphone, you should use the mic in port, as it is specifically designed to handle weak analog signals from a mic. On the other hand, if you are connecting a device with a line-level output, such as a mixer or an amplifier, it is best to use the line in port to ensure the highest audio quality without any additional amplification.

In conclusion, mic in and line in ports serve different purposes in analog audio recording. Mic in is designed for weak signals from microphones, while line in is designed for stronger, pre-amplified signals. Choosing the appropriate port depends on the audio source you are connecting, so be sure to use the one that is most suitable for your recording needs.
