Speaker Protection Board Dual Relay Voltage Regulator Circuit Module DIY Kit AC 12-24V

hello welcome to my another video this video contains information and connection of DIY relay circuit of DIY amplifier before we start let's learn about relay meanings an important feature of an audio amplifier is to provide a system to protect your speaker's in case the amplifier breaks down and puts DC on the speaker terminals the purpose of this circuit is to control the relay which turns on the speaker output relay in the audio amplifier the idea of the circuit is wait around 5 seconds after the power up until the speakers are switched to the amplifier output to avoid annoying thump sound from the speakers another feature of the circuit is that is disconnects the speaker immediately when the power in the amplifier is cut off so avoiding sometimes nasty sounds when you turn the equipment's off you can locate the relay circuit at the output of the main stage of the audio amplifier if
