Audio Amplifier Components

AudioScaleurs to keep in mind as a beginner to the world of hi-fi amplifiers is this: The amplifier is the key link between the music source (CD player, iPod, turntable etc.) and the speakers. Understanding this simple fact can go a long way in helping you choose the best hi-fi amplifier for your needs. There are many models available in the market, and each one of them performs quite differently. There is no point in splurging on a top-of-the-line hi-fi amplifier when all you need it for is to listen to some low-quality music.
In order to understand the difference between a regular music device and a hi-fi amplifier, you need to know what frequencies are used by music experts. Music experts utilize all types of frequencies, from classical music to modern jazz. These are all dependent upon the type of music that was created. The frequency response of a device can be classified into three classes, which are:
Class A - It is capable of producing low level audio signals and can reproduce the audio to a higher frequency level. The audio produced is usually very good. For most people, the Class A amplifier would be suitable for their needs. There are few factors to consider when purchasing a Class A amplifier like the maximum power consumption (which will depend on the use of the amplifier), the minimum voltage needed (more on the voltage), the efficiency of the device and the efficiency of its design (more on the design). The efficiency of a Class A amp would also depend on the wattage consumption, which is typically between fifteen to thirty-five watts.
Class B - This amp can reproduce audio at a higher frequency. It is intended for use in high fidelity audio systems. Some Class B amps can go up to sixty-eight of. This is a good amplifier to use if you are looking for a high fidelity amp without spending a lot of money. However, it tends to produce lower quality audio.
Class AB - This is one of the oldest forms of amplification. It has a very large power supply circuit and high wattage rating. However, most Class A amps are limited to using only one channel, which limits the number of combinations that can be created. There is one advantage of using a Class A amp that is worth mentioning, however. They are very quiet under all circumstances.
Class AB amplifiers tend to have more options available than Class C or D amplifiers do. These Class A amps allow you to set the maximum power that the device is capable of consuming. If you want the loudest sound from your amplifier, then you may want a Class A amp. On the other hand, if you want some distortion, then a Class B amp will do the job just fine. There are even some Class C amp models that come equipped with a variable speed control to further control the speed of the fan.
The final thing that you should consider when looking at an amplifier is its input signal level. Basically, this refers to how much voltage is supplied to the audio source. The input signal will determine the maximum power that the amplifier can deliver. The output voltage, on the other hand, will define the level of sound that the amplifier can produce. This is usually measured in ohms, but the amount of voltage used to supply to the audio source will also have an impact on this value.
The above information is necessary for the majority of models. It will give you the necessary information to make an educated decision as to which amp to buy. Furthermore, it will help you compare models with ease. Just make sure to keep the above information in mind as you start shopping so you won't be confused when it comes time to make your final purchase.
