Microphones: Sound Cards

The microphone is an object that can convert sound pressure waves into electrical signals.
Microphones are classified mainly according to the type of operation and the directivity (or the different sensitivity of the microphone relative to the direction of origin of the sound). Other specifications are the frequency response, dynamics and sensitivity, impedance, or the need for less power. Then there are the psycho-acoustic characteristics: transparency, sound, transient response, selectivity, yield on the harmonics, and so on. Basically
microphones current can be divided into two types:
- DYNAMIC: A battery with the classic on / off. They have their power on transients (on the dynamics of sound) and thus are generally used for the drums the drums, guitar flying, bass, various percussion, vocals (especially for live)
- CONDENSER: Apart from old models, they feed through the canon-XLR cable. Pressing the button "phantom power" on the mixer, it switches the current on the microphone inputs and electricity (48 volts) arrives to the microphone. They have their strength on the quality of sound and therefore are generally used for cymbals, piano, guitar and bass "Arranged" as scenic environment. Susceptible isolates ambient noise.
