1. What is an audio amplifier and what does it do?
An audio amplifier is a device that amplifies an audio signal, such as music or speech, to a higher voltage or current level to drive speakers or headphones, ensuring that the sound remains clear and accurate when played at higher volumes.
-
2. What is a power amplifier and how is it different from an audio amplifier?
A power amplifier is a type of audio amplifier designed to drive high-power loads such as speakers. It is capable of amplifying audio signals to a sufficient power output to drive speakers to produce greater volume.
-
3. How to choose a suitable audio amplifier?
When choosing an audio amplifier, factors such as output power, total harmonic distortion (THD), signal-to-noise ratio (SNR), efficiency, impedance matching (speaker impedance), and power consumption should be taken into consideration to ensure that it is well-matched with the speakers and audio source equipment.
-
4. What is the Total Harmonic Distortion (THD) of an audio amplifier?
Total Harmonic Distortion (THD) is the distortion component introduced by an audio amplifier during the signal amplification process. the lower the THD, the closer the amplified audio signal will be to the original signal, and usually high quality audio amplifiers have a THD value of less than 1%.
