Class A amplification

Class A amplification is a type of electronic amplification where the device’s output element (like a transistor) conducts continuously, even with no input signal. This ensures high fidelity because the output closely mirrors the input without distortion. However, it’s not very energy-efficient, as it consumes power constantly, generating heat even when no sound is being produced. Class A amplifiers are prized for their sound clarity and minimal distortion, making them popular in high-quality audio equipment despite their lower efficiency.
