The audio amplifier amplifies the signal output from the stereo to send more power to the speakers and optimizes the sound diffusion.

Amplificatore n.1

An amplifier is not only used to increase the power to be sent to the speakers, but also to optimize the stereo system as a whole.

The benefits of a separate amplifier:

  • Allows you to send more power to your speakers while minimizing distortion
  • They are optimized to make the subwoofer work in the most suitable way.
  • They are normally equipped with crossovers that simplify the installation and make an optimal performance of the speakers.
  • The speakers are powered by a power source independent of the player, thus optimizing the absorption and performance. In addition, amplifiers normally use a Mosfet power supply that optimizes absorption especially on the highest peaks and commonly does not require the installation of a separate capacitor.

Depending on your stereo system, the amplifier must have an appropriate number of channels:

In the case of multi-speaker stereo systems it is advisable to install more amplifiers, in which case it must be ensured that the main amplifier has a preamp output.

Prerogative Techniques

  • Frequency response, the wider the range, the better the amplifier. A value of 15 Hz to 35,000 Hz is a good compromise.
  • Signal to Noise Ratio (Y/N), the higher the value, the lower the noise. A value of >90db is a good compromise.
  • Distortion, the lower the value, the lower the distortion. A value
  • The RMS or peak power, it will be necessary that this is in line with the power of the speakers or subwoofers of the system.
