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 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. 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. 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.
