Power amplifier 65W with HEXFET

A medium power amplifier that is characterized by a lot of good sound quality, but simultaneously is very simple in the construction. It uses, enough time in active loudspeakers. In its output stage exist the very good FET transistors, technology HEXFET, transistor which are controlled by voltage and not by current as the classically bipolar transistors.

Additional Content: The medium power amplifier is an excellent choice for audio enthusiasts seeking high-quality sound output. Its simplicity in construction does not compromise the quality of sound it produces, making it a popular choice among users. The amplifier is frequently used in conjunction with active loudspeakers, enhancing the audio output and providing a richer sound experience.

At the heart of this amplifier lies the Field-Effect Transistor (FET), specifically the HEXFET technology. HEXFETs are renowned for their superior performance in audio applications due to their high input impedance, high-speed switching, low intrinsic capacitances, and robustness. These characteristics make them ideal for use in the output stage of the amplifier.

Unlike the conventional bipolar transistors that are current-controlled devices, FETs, including HEXFETs, are voltage-controlled. This means that they require almost no input current. This characteristic of FETs allows for lower power consumption, reduced distortion, and improved thermal stability.

The voltage-controlled nature of FETs also provides the advantage of a high input impedance. This high input impedance makes the amplifier less likely to load down the source, ensuring that the amplifier can handle a wide range of input signals without distortion. Thus, this medium power amplifier is not only simple in its construction but also efficient and reliable in its performance.A medium power amplifier that is characterized by a lot of good sound quality, but simultaneously is very simple in the construction.
