Frequently Asked Questions
A regulated, high-quality DC power supply with sufficient amperage is crucial to prevent noise and ensure stability. Consider a unit with surge protection as well.
The built-in limiter provides basic protection, but an external, more sophisticated limiter offers finer control and potentially better sound quality if you’re pushing the amp’s limits.
It’s best suited for background music or paging applications where consistent, reliable power delivery is prioritized over complex mixing and effects.
