Various Suggestions In Order To Help Understand The Noise Performance Of Recent Stereo Amps

To help you choose an audio amp, I am going to describe the term “signal-to-noise ratio” that is usually used in order to depict the performance of audio amps.

After you have narrowed down your search by glancing at a few key criteria, including the amount of output power, the size of the amp and the price, you are going to still have quite a few products to choose from. Now it is time to take a look at a couple of the technical specs in more detail. Subsequently listen to the loudspeaker which you have connected. You are going to hear some amount of hissing and/or hum coming from the speaker. Next compare several amplifiers according to the next rule: the smaller the amount of static, the higher the noise performance of the amp. Those components will produce some amount of hiss. The majority of of today’s amps are based on a digital switching architecture. They are referred to as “class-D” or “class-T” amplifiers. Switching mini stereo amplifiers include a power stage which is constantly switched at a frequency of approximately 400 kHz. This technique was designed with the knowledge that human hearing perceives noise at different frequencies differently. Then again, signals below 50 Hz and higher than 13 kHz are hardly heard. e any kind of digital switching components and for that reason usually possess lower music distortion as compared to switched-mode stereo amplifiers. The major downside of analog stereo amplifiers compared with switching amps is the small power performance. Another choice is to use heat sinks.
