Class H Amplifier Schematic Diagram

By | April 7, 2018



An amplifier is often the most important component of any audio system. Class H amplifiers are a special type of amplifier that is designed to operate with greater efficiency and accuracy than traditional amplifiers. They are highly sought-after for their superior performance, but how does one work? To understand that, we must first look at its schematic diagram.

Class H amplifiers employ a power supply design known as a "power bridge." This allows them to efficiently switch between two different voltage levels during operation. The switching of the power supply allows the amplifier to maintain an optimum voltage level while not exceeding the maximum current available. This ensures accurate and efficient sound reproduction.

The main components of a Class H amplifier include a preamp, power supply, and output stage. The preamp processes signals from a source such as a microphone or instrument and amplifies them to a suitable level before they reach the power supply. The power supply then converts the electrical energy into the optimal voltage levels required to drive the output stage.

The output stage is where the amplifier takes the electrical signal from the preamp and amplifies it to a level suitable for driving speakers. This section typically consists of an array of transistors or integrated circuits. These can be arranged in a number of ways depending on the design of the amplifier.

To conclude, understanding the schematic diagram of a Class H amplifier is key to unlocking its superior performance. It is essential for those serious about audio to familiarize themselves with the components of this type of amplifier and how it works to ensure an optimized listening experience. By understanding these components, audio engineers can maximize the performance of their systems and get the best possible audio quality.
