Speaker Protection Circuit Diagram. This current may damage the speaker especially in case of direct coupled amplifier. It has three wire power positive negative and ground.
Power amplifier speaker protection circuit schematic. Figure 1 protection mute circuit diagram the nominal supply voltage is 5 1v obtained via r13 and regulated by zd1 and this powers the complete circuit. This is much safer for the speakers and the arc to earth will blow the fuse a lot faster than if an 8 ohm load is a part of the circuit.
This is the speaker protection circuit provides stereo speaker protection and prevents switch on clicks and dc components on the output of the amplifier connected.
This is much safer for the speakers and the arc to earth will blow the fuse a lot faster than if an 8 ohm load is a part of the circuit. While switching a power amplifier on a loud thump sound is heard to sudden heavy discharge current through the speaker at the time of power on. This way even if the contacts do arc it will be directly to earth. 25w mosfet power amplifier 25w mosfet power amplifier is quite simple and uses 2.
