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.
