Good Level Audio Levels
Mic level - The level (or voltage) of signal generated by a microphone. Typically around 2 millivolts. Compare this with the two normal line levels (1.228V:+4dBu and .316V:-10dBV)
Phono Level - little larger than mic level also has equalization based on standardized RIAA curve. use phono input a line
Line Level - . There is an international standard for the level of inputs; it is around -10dBV(.316V) for semi-pro equipment, and about +4dBu(1.228V) for "pro" equipment. Line level outputs can come from tape decks, CD players, tuners, DAT decks, effects, etc.
Speaker level - higher voltages for speakers Rane Pro Audio Reference dB Interactive Design Tools: Utilities : VRMS / dBm / dBu / dBV calculator Analog VU meter - nominal level 0dB Digital Meter - nominal level -12dB - 16dB
Red line shows last Peak. Numbers at the top show loudest Peak.
Transducer = a device that converts one type of energy to another. A microphone converts acoustic energy to electrical energy. A speaker converts electrical energy to acoustical energy. They are both transducers.
