Car Audio Terminology
Head Unit The control unit is the heart of the car's sound system, is usually in the middle of the dashboard. Head units give the user the control of the vehicle entertainment media: (AM / FM radio, satellite radio, CDs, cassettes, although these are now rare), MP3, GPS navigation, Bluetooth, etc. A head unit is also known as a receiver.
Subwoofer A subwoofer is a woofer, or a complete loudspeaker dedicated to the reproduction of bass audio frequencies.Subwoofer, also known as "bench", used to extend the low frequency of local speakers. Subwoofers are supported by mounting one or more woofers typically 8 to 21 inches in diameter at a well-constructed wooden or plastic casing. Passive subwoofers have a subwoofer driver and enclosure, powered subwoofer, have an integrated amplifier.
Amplifier-rule, an amplifier or simply amp, is a device that changes, increase in general, the amplitude of a signal. The "signal" istypically voltage or current. Amplifiers are either in mono-channel 2-channel or multichannel configurations made so that you increase the signal to more than one audio component.
Capacitor car audio capacitors are basically energy storage in the car. These capacitors accumulate the power amplifier for producing great sounds to much. This power is released when the power demand exceeds the supply capacity of the power system of the car.You hear the booming bass sounds and songs with the much needed stamp only because of audio capacitors. Car audio capacitors are also known as stiffening capacitors.
Crossover Audio crossovers are a class of electronic filters designed specifically for use in audio applications, especially hi-fi. Frequently used speaker drivers are for the entire audio spectrum with acceptable volume and the absence of distortions unfit for themselves. To serve the crossoverThe aim of the allocation of the audio signal into separate frequency bands, which can be treated by optimizing the individual speaker drivers for these bands.
Tweeter: A small loudspeaker designed to high tones in a high-fidelity audio system to reproduce. A tweeter is a rule, the high frequencies of around 2,000 hertz to 20,000 hertz (20,000 Hz) is generally considered the upper limit of human hearing.
Blue-tooth-Put simply, Bluetooth technology allows youto wire Lessly stream digital music from almost any audio player to another. Used mostly by more experienced and advanced car audio users.
EQ-A-Car audio equalizer can be used as high-fidelity audio controls are defined. The equalizer allows the user to control various frequency bands in an audio system. The user can also graphically or digitally (depending on the equalizer design) these sound frequencies using the equalizer. A regular car audioEqualizer includes several audio filters or amplifiers. Each audio filter is based centered on a specific frequency in the audio range. The user can then decide which frequencies need to be strengthened and must be dismissed. This requires a degree of skill.
