Built-in lightning protection circuit effectively protects the amplifier and ensures normal operation in harsh outdoor environments. Built-in voltage stabilizing circuit allows normal operation within wide input voltage range. The overall waterproof design has a waterproof rating of IP67 and can work normally outdoors for many years.
