Mic and line-level signals use different types of audio connectors. The Differences in connectors and accessories However, the input and output in other updated mixers are switchable from mic to line levels. This happens because line signals are stronger compared to what a mic input accepts. When you connect a line-level input to the mic input, the sound produced will be very loud and distorted. Now you're probably wondering what happens when you change the inputs? Will there be sound or will you damage your equipment?

Mic in is used for microphone inputs while most audio equipment like consumer equipment and professional musical instruments uses line-level signals. For these devices, the best input would be a line input. Mic inputs require about -5 mv as CD and MP3 music players create a sound of 100+ mv. The resulting sound, or if there is any sound at all, will be so soft you can barely hear it. Line inputs cannot be used in a mic input. There are also pre-amps, mic to line amplifiers that convert mic-to-line, and other multi-channel equipment. One of the most common pieces of equipment is a mixer which can combine a variety of signals to create one output. There are many kinds of devices that help convert mic levels to line signals. If you do plug one, you will hear a weird sound that will be completely mixed up. Again, a mic will not work with this type of input.

Their inputs are somewhat similar to mics at 5 mv. These retro devices have different frequencies that will suit their needs. Two standard line levels exist: one for MP3 devices, DVD players, and other consumer equipment and have -10 dBV and one for professional equipment like mixing desks and signal processing devices with +4 dBu.īut when you want to connect record players and turntables, it’s another thing. Line signal moves from the pre-amp to the amp which works the speakers. The Differences in input and connectivityĪ mic and a line do not operate on the same input. This is why microphones need a pre-amp to convert the signals to line level. There are four kinds of audio signals and the weakest of all is mic level. The voltage may vary depending on the changes in the source’s signal and sound levels. This is why you cannot use a mic in as line in. A line signal is 1,000 times stronger than a mic in. Mic level signals are created by a mic as it collects sound which is about 1,000th of a volt.
