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 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. -
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 signal-to-noise ratio (SNR) of an audio amplifier?
Signal-to-noise ratio (SNR) is a measure of the ratio of the audio signal to the background noise, with higher values indicating less noise in the audio signal. A high SNR usually means clearer sound output.
