Features:
1. The noise of the switch is small and will not have too much impact on the speaker. It is still recommended to add a horn protection circuit. The horn protection circuit can not only eliminate the impact noise of the power amplifier switch, but also avoid the output DC burning the horn when the power amplifier is damaged.
2. The bottom noise is very small; even the ears close to the speaker, you can hardly hear the noise.
3. Zero drift is small, no need to do any debugging after installation, the output zero drift voltage will generally not exceed 50mv, and is relatively stable.
4. Adopt classic circuit, the work is stable and reliable, and some misoperations in the production will not necessarily damage the components, featuring a certain durability, and the production success rate is high.
5. Free debugging. As long as you install it correctly and there are no human errors, it is basically a one-time success. There is no need to do any debugging. Beginners also have a very high success rate.
