People often get confused by the different terminology used when talking about a Surround Sound Amplifier. In fact the whole subject of home cinema systems is awash with many different terms describing the same thing. A home cinema is a home theatre or even just a home surround sound system. If we take a look at the main components of a home cinema system it will help you to better understand some of the terminology.

A home cinema system is usually made up of three major elements. There are many variations within these elements but basically three majors.

The Screen.

Self explanatory really. The screen can simply be your television, or in high end systems you may use a digital projector. It is possible to project a large picture onto a screen or even a wall for viewing, giving a really effective home theatre feel.

Input Devices.

Basically whatever you use to input your sound and pictures. Your cable system, a Blu-ray or DVD player, iPod and gaming consoles are also popular for use through your home cinema system. With modern systems you can add a number of different input devices.

The Sound System.

How the sound is processed and delivered to your room. The sound system is arguably the core of your system. There are a wide range of options available when choosing a sound system.

The sound systems used for home cinema will normally come as a package or an integrated system. This will be made up of a surround sound amplifier and the speakers. The speaker system can come in a number of different configurations with 5.1 sound being the most common at this time. 7.1 sound systems are fast catching up and as their price drops in time will become the market leader. Just to explain a little, 5.1 set-ups have six speakers - 5 main speakers, often called satellite speakers, and a subwoofer (the.1), which is a specialised speaker that delivers low frequency sounds and bass.

The surround sound amplifier is also referred to as the Receiver or A/V Receiver. Think of this like your amplifier on you Hi-Fi. It basically processes the sound from your input device into channels to suit the speaker configuration. It controls the volume and amplifies the sound for delivery to the speakers. The integrated surround sound amplifier will manage all these processes and allow you to easily select different input devices and control the sound set-up. It is the brains behind the operation and as such should be where you spend your money. A good sound system will be at the heart of any home cinema set-up.

In some high specification systems the integrated amplifier is replaced by separate components. Here you would have a surround processor and a separate sound amplifier.This can become very expensive and complicated. The quality of integrated systems today are such that buying a separate processor and surround sound amplifier is not really worth the extra time and investment. So good luck and have fun in your search for the perfect sound system.

Car Audio Accessories in 2010

There are various advanced car audio accessories available in the market which can be attached to or used with the car audio system. The price of such add-ons can be equal to or even exceed the price of the audio system. Many such accessories are available for people with a liking for a better sound or the best sound. They vary greatly in their quality and price range.

Nowadays, audio systems with the capability of playing from external storage devices like pen drives, external hard disks, and iPods, are available in the market. The user is free from the trouble of carrying several audio or MP3 CDs in the car. Facilities of this kind certainly improve the user's listening experience.

The XM satellite radio is also a good example of car audio accessories, and it provides a good package of music, news, and talk shows. It is capable of supporting over 170 radio stations, and that too with a crystal clear sound quality.

A docking station is a useful car audio accessory that can be used in the car as well as at home. Along with providing the best sound output from the iPod or an MP3 player, it can also display images on the monitor. Moreover, it also has a remote control.

Similarly, there are many types of car amplifiers, radios, speakers, and sub-woofers that can enhance the total audio experience of the passengers in the car.

Car Audio Capacitors

A car audio capacitor is a part that stores the power which is needed for the amplifier to efficiently provide the desired effect and sound. The deep bass along with the clarity is the result of a good quality car audio capacitor. Most people know it as a stiffening capacitor. It is responsible for storing power whenever it isn't needed. It is called into action when the demand for power surpasses the supply capability of the car's power system.

If you are playing music with a loud bass and sound, and not using a capacitor, the extra power which is needed will be taken from the lights, air conditioner, or even the engine. Most of the time, the lights turn dim and follow the beats of the music, and when you turn off the lights, the music volume suddenly increases and the sound becomes clearer.

An audio capacitor is essential to add on to the normal power supply of the car for a smooth functioning of the audio amplifier. Generally, car audio capacitors having a capacitance of 0.5 farads to 3.0 farads are available in car audio stores. An audio capacitor should be compatible with the amplifier, and should also be positioned as near as possible to it. If you need to get a power output of 500 RMS, you are required to use one with a capacity of 0.5 farads. Nowadays, digital ones are also available which normally have a capacitance starting from 1.5 farads.

You may choose among various car audio MP3 capacitors from several reputed brands, but just determine if they are compatible with your car's amplifier. Car audio capacitors have certainly proven to be one of the most important and advanced parts in the car's sound system.

What does bypassing a factory amplifier do to a car audio system with and aftermarket head unit and 2 subs?

i recently went in to get my amp fixed at a local shop. While doing the procedure the audio guy told me that by not bypassing the factory amp my sound was being distorted. Is this true? or was he just trying to tac on the bill. if it is true is it something i could do?

He feed you a line of crap, since the car more than likely did not come with any sub installed in it. There for the amp was running to your full range speakers, just like it would have from the factory to your speakers. The subs are an add on, which would require an add on amp for them, so there would be no distortion to the speakers what so ever. They ripped you off is what they did.
