Class A Amplifiers

Class A amplifiers are electronic devices that amplify audio signals with high fidelity and minimal distortion. They operate by biasing their output devices (transistors or tubes) so they conduct current throughout the entire input signal cycle, meaning they are always on. This continuous operation ensures the amplified sound is very accurate and clear, making Class A amplifiers ideal for high-quality audio applications. However, they tend to be less efficient, generating more heat and consuming more power compared to other amplifier classes. Their design prioritizes sound quality over power efficiency.
