Transistors conduct for the full 360° cycle; generates significant heat. Poor (High Distortion)
The "Class" of an amplifier refers to how its output transistors are biased and how long they conduct during an audio cycle. Each has distinct trade-offs in efficiency and sound quality: Efficiency Typical Sound Quality Key Characteristic
Only conducts for 180° of the cycle; prone to "crossover distortion". Excellent (if well-designed)
The "front end" that accepts the weak input signal and provides the necessary voltage gain.
The final powerhouse connected to the speakers. It translates the high-voltage signal into the wattage needed to physically move the speaker cones. Choosing Your Amplifier Class
The Art and Science of Designing Audio Power Amplifiers Designing an audio power amplifier is often considered one of the most challenging tasks in high-end audio engineering. It is the delicate process of taking a small, millivolt-range input signal and scaling it significantly—sometimes up to 40 times larger—to drive complex loudspeaker loads with precision and minimal distortion.
