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. 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.

3. 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.
-
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.
