1. The noise of the switch is small and has little effect on the speaker.
2. The zero-drift output voltage generally does not exceed 50 mV and is relatively stable.
3. There is no need to do any debugging after installation, and beginners have a high success rate.
4. The horn protection circuit can eliminate the impact noise of the power amplifier switch.
5. It also prevents the DC output from burning out the horn when the power amplifier is damaged.
