Things to Consider Before Buying an Amplifier

Amplifiers or amps are used to boost an electrical signal. Hence it is essentially used in home theatre systems for boosting up the volume or audio signals. An amplifier is usually considered to be the core of your home theatre.

Connectors – One of the important aspects to consider when buying an amp is the connectors set on-board. These devices are equipped with various connectors or ports for connecting multiple other devices (like music system, DVD player or Blu Ray player, speakers etc.). In case you already have a furnished home theatre, then you’ll have to choose an amp that will be compatible with all the available devices. In case you still have to buy all the other equipment, then you can choose an amplifier based on your entertainment requirements and budget.

Specifications – The electrical specifications, like the power rating, also need to be considered when buying an amp. For example, if you have speakers of a particular power rating, you’ll need to choose an amp compatible with them.

Extra features – A basic amplifier will just do regular audio signal boosting. The newer high-end ones are capable of decoding high definition sounds as well. Such amps can be of great use, especially when you have a Blu Ray player at home.

Stereo and Surround sound amps – Stereo amps are simply two-channel amps that can decode music recorded in 2-channels. Music from a CD is an example. Some modern amps support surround sound. These devices can decode sounds from 6 channels for a surround sound experience.

Several amplifier brands are available in the market like Sony, Yamaha, Pioneer, Bazooka, Arcam, Philips, Samsung and more. Thus you have a vast variety to choose from.

Budget- Budget is an essential factor that can affect your choice. If you don’t have a tight budget, then you can always go in for a top-notch, feature-rich amp. If you’re someone with a taste for décor, you can also go in for amplifiers with an exquisite finish.

A look through into the Amplifiers

Amplifiers or an amp, as the name suggests, amplifies the weak signals into stronger ones. In simple terms, it boosts the electrical signals. Amplifiers are the only solution to increase both the current and the voltage. These are also applied in musical instruments such as the guitar.

Amplifiers such as a transistor, vacuum tube or valve, fully differential and operational, are used for a particular purpose. Earlier amplifiers were normally used in appliances such as telephones, radios, and TV. Later amplifiers were commonly used to amplify sound waves of low frequency. These are called as subwoofer amplifiers. The use of amplifiers are restricted to only control the volume of sound.

Later, technology developed, and the role of the amplifier was elaborated. Now that the amplifiers are used not only to boost the sound signals but also to bring out the clarity to the contents. By adjusting the amplifier, listeners can add accent to vocal messages or contents in a stage program or to the background instrument music.

Amplifiers these days are made of solid-state electronics, although some are made of vacuum tubes. Electrical noise is reduced by the use of toroidal transformers for power supply.

Now let’s go through various types of amplifiers. Few electronic amplifiers are power amplifier, transistor amplifier, vacuum tube amplifier, operational amplifier, video amplifier, fully differential amplifier, microwave amplifier and musical instrument amplifier. And few other amplifier types are carbon microphone, rotating electrical machinery amplifier, magnetic amplifier, optical amplifier, mechanical amplifier, and Johnsen-Rahbek effect amplifier.

Some important features of an amplifier are Linearity, Noise, Gain and Dynamicrange. Linearity measures the proportionality of the output signal to the input signal. Noise is referred to as the amount of unwanted interference or static that is added by the amplifier to the input signal. Gain is the ratio of the power of the input and the output. Dynamicrange is the part of the output signal that is useful. It lies in between the distortion and the noise levels.

The sky is the limit for the development and researches done in Science and Technology. So one can surely expect amplifiers to be used in a number of applications found here.
