What Is an Amplifier?

Amplifiers for sale are plentiful online, which shows just how in demand they are. These electronic devices, also colloquially known as amps, increase the magnitude of a signal applied to their input. The signal could come from a bunch of things — including a musical instrument or a mic.


As they make sounds louder and better, they are essential if you’re in the music or audio industry. They have a variety of applications, from casual home audio systems to live events and performances. 

What Are the Key Features to Consider When Buying an Amplifier?

If you want a cheap amplifier that won’t disappoint, you have to inspect its features carefully. These include the following:

  • Power output. Measured in watts (W), this determines how loud your sound can play. The optimal power output will depend on how and where you’ll use the amplifier. For instance, 20W amplifiers are already suitable for practice electric guitar sessions in medium-sized rooms.

  • Signal-to-noise ratio (SNR). The higher this figure, the clearer or less noisy the music your amplifier will produce. 

  • Total harmonic distortion + noise (THD+N).  The lower this number, the closer or less distorted the sound will be to the original input. 

  • Crosstalk. This feature refers to an amplifier’s capacity to keep left and right audio channels separate. An amp with a higher negative dB indicates better separation. It allows you to better identify if a sound (for example, a guitar sound) comes from the left or right side of the room. In essence, it creates a more immersive sound experience. 

  • Inputs. Your amplifier should be able to cater to your devices. A dual-input amplifier allows you to connect two different audio sources simultaneously.

  • Tone controls. These controls let you “shape” the sound output to your liking. Usually, amps have controls for bass, middle or midrange, treble, and gain. 

How Do I Choose the Right Amplifier for My Setup or Instrument?

When shopping for amplifiers online, consider the size and acoustics of the venue where the amplifier will be used. Larger venues require more power than studio setups that have acoustic foams.


Also, note that different instruments may require different types of amplifiers to reproduce their sound best. An electric guitar benefits from a quality yet cheap guitar amp to enhance its tone. 

Are There Specific Amplifiers Designed for Guitars, Bass Guitars, Keyboards, or Other Instruments?

Yes, there are different types of amps tailored for specific instruments. Guitar amps usually have controls for tone shaping. Bass amps, on the other hand, boast robust power outputs to reproduce bass tones accurately. Meanwhile, keyboard amps often have multiple channels and full-range speakers to handle various sounds produced by keyboards.

When buying a cheap amplifier, remember that it all really comes down to intended use.
