How To Build A Great Home Stereo System
A home stereo system is built up of several components. Firstly, it must contain an audio source, such as a CD player or MP3 player. The next component in the stereo is a preamplifier which reads and decodes audio information sent from the source to the amplifier. The amplifier increases the power of the signal to properly drive the speakers. Finally, the speakers convert the electrical audio signal to sound. In some systems, the amplifier is combined with the preamplifier in devices like receivers or integrated amplifiers.
The preamplifier serves as the brain and control center of your home stereo stereo. It reads the signal generated by the input device, breaks it down into appropriate channels (i.e. left and right for 2-channel audio), increases the voltage of the signal slightly from a source like a CD player, and then sends it to the amplifier.
The amplifier boosts the signal from the pre-amp, adding significant power. The signal sent from the preamplifier is far too weak to effectively drive the speakers and vibrate the coil so that you can hear sound. It's the amplifier's job, therefore, to boost the power of the signal so that it can properly drive the speaker cones generating the sound that you enjoy.
The final components in a stereo system are the speakers. There are several different types of speaker available. Subwoofers and woofers are designed to deal with the ultra-low bass frequencies, creating the backbone of the sound. Mid-range speakers deal with the mid-range frequencies, while the tweeter speakers are built to handle the highest frequencies. All these types of speaker are essential for creating a full, balanced and complete sound.
It is possible to buy the components separately for a stereo system. This method requires extra time and patience to set up, and often costs more, but the results are obvious. Custom built systems often deliver much higher quality and versatility than many "all-in-one" systems. The main advantage these "all-in-one" systems is the sheer simplicity. They take very little effort to set up; basically plug it in, connect the speakers, and sit back and enjoy the sound. It is important to carefully plan out your home stereo system, avoiding overspending, or even buying too powerful a system for the space you have available.
