It is strongly recommended to use an independent power supply — do not share a power supply with your power amplifier, as this can affect the board's performance and reliability.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the boot delay feature do on this speaker protection board?\u003c\/h4\u003e\n\u003cp\u003eA: The boot delay introduces a 3–5 second pause after power-on before connecting your speakers. This prevents the loud transient pop or thump that can occur when an amplifier starts up, helping to protect your speakers from sudden voltage surges during power cycling.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this speaker protection board kit pre-assembled or do I need to solder it myself?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This is a DIY unassembled kit.
