1. 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%.
-
2. What is a Class D audio amplifier and what are its advantages?
Class D audio amplifiers work through Pulse Width Modulation (PWM) technology and have extremely high efficiency (typically up to 90% or higher), making them suitable for use in portable audio equipment or high-efficiency sound systems. It generates less heat because it reduces energy consumption.

3. How can I improve the thermal performance of my audio amplifier?
Audio amplifiers generate heat when they operate, especially Class A and Class AB amplifiers. Ways to improve heat dissipation include using a larger heat sink, adding a fan, or using a more efficient Class D amplifier. A good thermal design will improve the performance and life of the amplifier.
-
4. What should the frequency response range of an audio amplifier be?
The frequency response range of a good quality audio amplifier is usually between 20Hz and 20kHz, which is the typical frequency range that the human ear can hear. A wider frequency response ensures that the audio amplifier can accurately reproduce both low and high frequency details.
