10A Dual Channel Speaker Protection Board with Power‑On Delay Control Audio Amplifier Relay Protector

Speaker Protection Circuit Board Key benefits Prevents speaker damage and audio artifacts during power on by delaying speaker connection until the amplifier stabilizes. Simple relay switching design makes installation and control straightforward for DIY audio projects and repairs. Compatible with common dual channel and 3 channel amplifier setups, offering flexible integration options. Features Protection method: power on delay with approximately 3 second relay activation time. Relay switching: two 10A relays used as switches for reliable audio line control. Voltage range: operates from DC12 to DC18V, suitable for a wide range of amplifier power supplies. Current rating: 10A relays support typical speaker and amplifier loads. Indicator and regulation: relay board can be equipped for 2.0 dual channel and 2.1 three channel systems with a blue indicator and voltage regulator circuit. Connection: designed to link easily with most 2.0 dual channel amplifier boards and compatible with many speaker setups. Specifications Material: cardboard Color: as picture Size: as picture Work voltage: DC1218V Current: 10A Relay count: 2 pieces of 10A relays Relay delay time: about 3 seconds Practical applications Home audio systems: add speaker protection to stereo amplifier builds to eliminate turn on thump and reduce risk to speakers. DIY amplifier projects: integrate the module into custom 2.0 or 2.1 amplifier assemblies for controlled speaker switching. and upgrades: or add protection circuitry to existing amplifier boards to improve system reliability during power cycles.
