An audio crossover is a type of audio filter generally used with audio systems especially in Hi-Fi audio systems. Usually the loudspeaker drivers used in audio systems are not capable to control the whole sound spectrum. So here the crossover plays a significant role and splits the audio signals in different frequencies bands, which can be handled by individual loudspeaker drivers. The combination of different frequency band is normally the pattern of Hi-Fi audio systems. An audio crossover may also be constructed mechanically and is normally used in full-range speakers, portions of whose cones or dust caps are decoupled at increasingly higher frequencies. There is another use of crossover called multi-band processing. Here audio signals are split into bands which are adjusted individually. After that these separate bands are mixed together again for instance bass enhancement, multi-band dynamics, multi-band distortion and high frequency exciters.
A perfect crossover splits the incoming audio signals in different frequency bands that do not interact. After that they are added together again.
There are many types of crossovers available in the market but all these types fall under the classification that is provided below.
Classification based on components:
- Passive crossovers.
- Active crossovers
- Mechanical crossovers
- Digital Crossovers
Classification based on filter order:
- First order crossovers
- Second order crossovers
- Third order crossovers
- Fourth order crossovers
- Higher order crossovers
- Mixed order crossovers
Classification based on circuit topology:
- Parallel crossovers
- Series crossovers
A passive crossover is normally used in the signal path after the amplifier. It is a type of a capacitor or coil installed right on your speaker lead. For installation of passive crossover first of all you need to remove your speakers from its location. Disconnect the positive lead of your speaker. There you connect the bass blocker. Then connect the positive lead to the other head of bass blocker, test its operation and reinstall your speaker.
Let’s take a look on the available crossovers manufactured by a well-known manufacturer Kenwood.
Kenwood KE-600 Crossover: It is a versatile and most of the advance crossover available in the electronics market now a day. It is a six way cross over for Hi-Fi audio systems having built in parametric equalizer and DC to DC power supply for high voltage outputs and low noise. It has variable level controls, different phase switches and subwoofer output from 30Hz to 800Hz.

Your Car Stereo System Needs Line Driver
A line driver is an amplifier used to develop the communication consistency of a normally digital intrafacility tinny transmission line, over unlimited distances, by driving the input signals to the transmission line with a higher than normal signal level, in telecommunication sector. In Mobile Audio systems, a line driver is a small amplifying device used to boost the power of the audio signal coming from the head unit. The newly reinforced signal is then transmitted to its suitable amplifier. Gain on an amplifier requirement to be set with the consideration to the input voltage the amplifier spots, the lesser the input voltage, the bigger the gain to create a certain loudness and higher the sound quality. When increasing a very low voltage signal, the noise floor of the amplifying system increases, meaning that the amplifier is not only amplifying the low voltage acoustic signal, but also the low voltage noises pulled out in the line along the way.
By using a line driver, gains of the amplifier must not be set at high level, thereby amplifying the acoustic signal with less of the low level noise. This function of the line driver can be useful especially in long runs of signal cable, which are more horizontal to picking up noise. Line Drivers facilitate long distance connections between one source and one destination, and are used to preserve video quality when driving video signals over long cable runs. Video signals normally lose amplitude and high frequencies on long coax cable runs. Line drivers provide variable gain control which can be adjusted to boost the video signal, compensating for the overall drop in signal voltage. Line Drivers are very useful devices that help much to enhance the overall performance of the car stereo systems. Line drivers permit the signals to go from the source to the output device easily. Line drivers are very high-tech and functional devices that widely used with car stereo system to improve the performance.
There are variety of Line Drivers are available in the market in different types. Line Drivers are available in different power ranges, sizes and price ranges as well. You should choose the Line Driver that is most suitable to your car stereo specification. Line Drivers are very cost effective and functional devices that take your music experience to the next level. Line Drivers are not only available at local car stereo stores but also at online car stereo stores at affordable prices. Online car stereo stores offer great deals on Line Drivers of different companies. You can buy all type of Line Drivers from online car stereo stores at very low prices as compared to the local market. You can also read reviews on the Line Drivers of different companies at various online sites and car stereo magazines.

Equalizer Gives You Full Control Over Sound
Today car audio system is considered essential part of your vehicle. With the help of the latest technologies, manufacturers are able to produce high quality car audio systems that can produce clear, noise free and loud sound. Basically a car audio system is a device which plays track. To produce high quality sound there are numerous components involved and a good car audio system must have an equalizer to set the frequency of sound according to your own taste. However a car audio system has a complex mechanism. Primarily an equalizer enables users to set the different frequency bands in an audio system and a user can see the frequencies either geographically or digitally depending on the model of equalizer. A general car audio equalizer consists of several audio filters and each audio filter is centered on a particular frequency in the audio-range.
The term "equalizer" is normally but imperfectly used as a common word for audio filters. DJ mixing equipment and hi-fi audio components often include so called graphic equalizers or simply equalizers. These are in fact general all-purpose filters, which can be used to produce the effect of low pass; high pass, band pass and band stop filters. To have an audio equalizer in your car is a plus point to boost the sound quality of your audio system so it can bring a fascinating enhancement. There are numerous types of equalizers. Most equalizers contain both high and low pass filters for all inputs. Nevertheless, whichever you choose will make a difference in your car audio system if used properly.
Car audio equalizer comes in various forms and sizes such as dash and trunk mount units with parametric, graphic or quasi-parametric processing either. The most common type of equalizer is graphic equalizer. It is available in dash from. Equalizers are normally half of a head unit in height but it varies model to model. In dash form of equalizer is much popular because it is easily adjustable.
A car audio equalizer can be installed any where in car but usually it is placed in the passenger compartment. It is generally mounted above or below the receiver in the factory radio location. In case there isn’t a sophisticated space left to place it, so it can be mounted below the dash with a bracket or special kit. After that you will need a connection with your 12 volts battery. Moreover you need to feed signals from your receiver. Finally you will connect equalized with your car amplifier with patch cables. Be sure to run your patch cords to avoid noise.
