Features:
1. This common power DC protection board uses an optocoupler. Since the optocoupler has input and output isolation,
2. Electrical signal transmission has the characteristics of unidirectionality, so it has good electrical insulation and anti-interference ability.
3. Since the input end of the optocoupler belongs to the low-resistance type of current type operation, it has strong common mode suppression capability.
4. The power and sound source are separated, and the sound source will not be affected
