1. What types of audio amplifiers are available?
Common types of audio amplifiers include:
Class A amplifiers: have the highest sound quality, but are less efficient.
Class B amplifiers: More efficient, but may produce crossover distortion.
Class AB amplifiers: between Class A and Class B with good balance.
Class D amplifier: highest efficiency, suitable for portable devices, but slightly lower sound quality. -
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 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.
