| − | Condenser mics usually have better dynamic range and frequency response but are more fragile than dynamics. Ribbon mics are the most fragile but have a very characteristic sound. The larger the diaphragm the better low end response the smaller the diaphragm the better the high end response.

| |
| − | Mic level - The level (or voltage) of signal generated by a microphone. Typically around 2 millivolts. Compare this with the two normal line levels (1.23V:+4dbV 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 for semi-pro equipment, and about +4dBV for "pro" equipment. Line level outputs can come from tape decks, CD players, tuners, DAT decks, effects, etc.
