An amplifier is the heart of a stereo system or microphone that boosts the signal before feeding it to any loudspeaker or headphone speaker which helps to magnify the original sound significantly.
An amplifier or amp is must-have equipment for improving the sound of any audio system, be it your home theatre system, car audio system or electric guitar.
An amplifier is used in combination with speakers to not only enhance the sound, but also control and improve the quality of sound including its bass and treble.
But when it comes to choosing an amplifier for your sound system, it is important to consider a few specs such as power output of the amplifier, controls of the amplifier, inputs and connection available in the amplifier, etc.
How to Choose an Amplifier?
1. Power
Power output of an amplifier measures the level of loudness of your amplifier. Bigger speakers will require more power output from an amplifier comparer to smaller speakers. An amplifier with 10 watts power output will be good enough for average listening.
2. Controls
The level of control that an amplifier has on the speakers is measured as damping factor of the amp. While most speakers can be easily controlled using any amplifier if it’s within the decibel range, there are some speakers that require special support from the amp in order to control reverberations close to the resonant frequency of the speaker. Solid state amplifiers often provide better control in this case compared to tube amplifiers.
3. Inputs and Connections
It is best to choose an amplifier with multiple and compatible inputs so that you can connect all the peripherals to it. Look for an amp that comes with 3.5mm inputs for iPods, phono for turnables and USB port for home theatres and laptops.
