Music is one of the most needed things to make a party super enjoyable and rocking. Without music, no party gets the mood where you can dance from your heart in your full mood. But music in a low volume is of no use at a party. This is why you need a good audio amplifier for the party. Not only at a party, sometimes you need to listen to loud music just to set your mood for a particular day. The sound system setup can be as simple as an amplifier with two floor standing speakers or can be a huge one with a set of subwoofers and midrange speaker combinations. However this is not just the matter of a party to make enjoyable, but there are several other incidents where you need to amplify the sound. In a road show or in a meeting where there are lots of people to hear you, you need an audio amplifier to make your voice loud and clear for them.
The Basic Concept of an Audio Amplifier
The basic mechanism of an audio amplifier is to convert the low-frequency audio signals into high power audio signals. The amplifier works on electric power and thus it is known as an electronic amplifier. The audio amplifiers can be found in all types of sound systems like a radio or an MP3 player. In fact, there are amplifiers in earphones also which we generally use to listen to music personally. This device is mostly used in the loudspeakers, public address systems, sound reinforcement systems, home theatres and so on. Some of the musical instruments also have the inbuilt amplifiers like the guitar amplifiers.
The output from a normal musical instrument may come out of some microwatts. The amplifiers help it to get multiplied by several times and up to some thousand watts in discos and nightclubs. As per the size of the amplifiers, the output of the sound is due. If the device is a standalone device, then the power of the amplifier is less and if it is used in the hi-fi programs then the power is huge.

The Invention
The need for amplifying the sounds was felt many years ago when the concept of civilization became prevalent. The instructions from the head of the society were to be circulated among the people and that’s why they need to have such a device that can amplify the sound so that everyone could hear it. Many inventions were made to make sounds amplified but the real invention came nearly in the 20th century. In 1912 the first-ever audio amplifier was invented by Lee De Forest. This was an electrical device that was named as the triode vacuum tube. A device with three terminals and a control grid which were used to modulate the electron flow to the plate from the filaments. It was widely used in the first version of the AM radio.
In the meantime, many inventors tried to make amplifiers using transistors and finally, it became practically possible as transistors became inexpensive and available in the second half of the 10960s. Fast developments and research bring BJT transistors into the market. Soon after that transistor with oxide-semiconductors field-effect became prevalent in use.
Key Parameters in the Designing Part
The basic function of an audio amplifier that you can get in a Planet Audio Amplifier review is to receive the frequency of the sounds and amplify it into such a quality of frequency that the sound can gain a high pitch. But during the inventions of the latest technologies, the biggest challenge that came in front was to reduce the noise and distortion.
The noise, gain, distortion and frequency response are dependent on one another and thus if you want to control one parameter then automatically the other gets disturbed. Till the year 1970, the technology was dependent on vacuum tubes and soon after they were replaced with the transistors. In the year 2000, a new type of amplifier was launched in the market which was known as class D amplifier and it was very much advanced in terms of the working capacity rather than the class AB amplifiers. This device became much lighter in weight and is capable of controlling the different aspects of audio differently.
Planet Audio Amplifier
One of the most famous companies that make these audio amplifiers is Planet Audio. They are masters in making these D type audio amplifiers. People who have bought these products have got really satisfied with these products and that’s why most of them recommend it. The performance of this product is excellent. It produces twice the natural output while connected to a 12-inch sub. The company makes products worth money. If you want to fit it with a non-bose system, then it is really a good choice. The fitting doesn’t need any kind of modification on the factory settings. Since the high pitches of any music are caught very easily, so it does with the low pitches.
Key Features
The Planet Amplifiers have the lowest impedance acceptance which is of 2ohms and these results in more power to generate more volume. They are also featured to accept both high level and low-level inputs that provide you better control over your device. Nevertheless, the amplifiers don’t get too hot that may cause damage to its parts.
These audio amplifiers contain sub-woofers and spread fantastic sound quality within the given area. There are different categories of amplifiers that can get fit into a car also. If you have purchased one for your car, then you have made the right choice. The sound is very smooth and there is no distortion of the base when you use it to make any audio loud. The company makes amplifiers of several capacities like 1800w, 900w so that everyone can buy the products as per their convenience.
Most of the people are very satisfied while using these Planet Audio amplifiers. Nearly 60% of people have rated it with 5-star ratings due to its high level of performance. Moreover, the prices are also very affordable for everyone. If you are really feeling the need for an affordable music amplifier then you can easily opt for it.
