The electrical level (voltage) of signal generated by a microphone. In contrast to line levels, which are typically around 1.23 V or 0.316 V, an unamplified microphone level may be around 2 mV.
The typical level of a signal from a microphone. A mic level signal (usually but not always coming from a microphone) is generally below -30dBu. With a very quiet source (a pin dropping?) the signal can be -70dBu or lower. It is also possible for some microphones to deliver more signal than this, in which case it may be referred to as a "hot" mic level. Alternatively, you can just say, "Boy, is that loud!"
A very low-level audio voltage signal generated by a studio microphone.
Audio signals whose level is similar to those of microphones, that is, generally ranging from roughly 0.001 volts (1 mV) to 5 volts.
is the low-level signal produced by microphones and electric instruments such as electric guitar or bass as opposed to amplified sound.
The level (or voltage) of signal generated by a microphone. Typically around 2 millivolts. Compare this with the two normal line levels (1.23 volts and .316 volts), and it becomes apparent just how much amplification is going on in a microphone preamp, and why it is essential that preamps be of as high quality as possible
Mic level is the first level of an electrical signal in a sound system. At mic level, sound picked up by a microphone has been changed to an electrical signal (usually measuring a few thousandths of a Volt).
The typical level of a microphone signal. Usually lower than -40 dBu.
