1. 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.
-
2. 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%.
-
3. 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.

4. 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.
