How To Choose a Reliable Audio Amplifier

Nothing beats the sound of clear and powerful audio sound. You can have enough music collections to last your entire event, but with low power output, your party will be incomplete. To solve this, you need to power up your speakers by bringing in an amplifier.

What will my Technics amplifier do for me?

Also known as a power amp, an amplifier is an electronic device used to magnify the amplitude of audio sounds. Your Technics home entertainment center is just that, a control center.

It receives waves from a number of sources around the home, be it CD players, tuners, or tablets, and magnifies them to the powerful versions that will be produced from your speakers

What types of amplifiers are available?

In the same way that televisions differ, amplifiers are also classified into four types. All have the same end result but work through different processes to execute this. These are:

  • Class A - This amp uses its available energy the whole time its running and amplifies the complete 360-degree cycles.
  • Class B - This amp works the old-fashioned way. It splits the amplifying task into two parts; one pushes waveforms halfway while another pulls the signals out the other way. Class B, however, distorts sound and has eventually been abandoned for the AB.
  • Class AB - This an improvement of class B amps. The technique in this type eliminates the distortion by smoothing their transition between the positive and negative waves.
  • Class D - This is the latest technology in the design of power amplifiers. Often mistakenly referred to as the "digital amp", most use digital signal processing.

What are some of the features found in an amplifier?

You will if your Technics stereo is worth it when you understand what features to look out for. Lets look at some of them:

  • Power output - This is relative to how loud you intend to play your music. Generally, the bigger the speakers you have, the more power you will need. Consider 10 watts for average use, and up to 100 watts for large parties.
  • Signal to noise ratio (SNR) - Background noise can ruin the smooth sound your stereo gives. To keep this noise down, ensure your amplifier has a high SNR.
  • Channel separation - This measures how much right input is mixed with your Technics left. The higher the number the better. Your Technics SU Z25, for instance, gives you 50 db.
  • Inputs - Your amplifier needs to have enough ports for all your connections. For instance, you need a USB port for your home theatre and laptop.
  • Total harmonic distortion + noise (THD+N) - This measures the effect that the stereo amplifier has on the sound. For clear sound and less distortion, get an amplifier that has a lower THD+N
