Abstract

The invention discloses a low-distortion power amplifier system based on a switch machine squelch circuit, which is characterized in that it mainly consists of a static bias circuit, a power amplifier circuit connected to the static bias circuit, a negative electrode connected to the static bias circuit, The positive electrode is used as the input capacitor C1 of the power amplifier system and so on. The invention can automatically perform mute when the power is just turned on, and eliminates the impact of high current on the speaker when the power is just turned on, thereby protecting the speaker.

Description

Technical field [0001] The invention relates to a power amplifier system, in particular to a low-distortion power amplifier system based on a switch mute circuit. Background technique [0002] The power amplifier system is the most basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source to drive the speaker to emit sound. However, the existing power amplifier system has a major problem, that is, the amplified signal is prone to different degrees of distortion, resulting in signal distortion, which seriously affects the auditory effect. Summary of the invention [0003] The purpose of the present invention is to overcome the defect that the current power amplifier system may easily distort the signal after amplifying the signal and cause signal distortion, and provide a low-distortion power amplifier system based on the switch mute circuit. [0004] The purpose of the present invention is achieved with the following technical sol...
