The difference between pure power amplifier and ordinary power amplifier

What is a pure power amplifier?

The pure post-stage power amplifier, referred to as the post-stage power amplifier, is an electronic device used to enhance the signal power to drive the sound of the speaker. A pure post-stage power amplifier without a pre-stage, that is, a power amplifier without auxiliary functions such as signal source selection and volume control, is called a post-stage. The pure post-stage power amplifier must pass through the pre-amplifier to be used normally.

The preamplifier is also called the front stage, the preamplification and control part before the power amplifier, which is used to enhance the voltage range of the signal, provide input signal selection, tone adjustment and volume control and other functions.

Pure power amplifier and

The difference between ordinary amplifiers

1. Compared with the traditional power amplifier, the design of the pure post-stage power amplifier, the sound of the speaker driven by the pure post-stage power amplifier will be better

2. The pure post-stage power amplifier lacks filtering function, which reduces the failure rate; while the traditional ordinary power amplifier is used for more than one year, it is easy to break down

3. The pure power amplifier GS6120 of the sound of Gypsy can easily promote the full active three-way frequency system of the 10,000 yuan level. For example, the GS6120 matches the Dynaudio 372.
