Power Amplifier Speaker Protection Circuit Diagram. An ocl amplifier pattern uses a dual power supply. Why use the speaker protection circuit.
Using resistors will work fine but you ll lose 1 2 power across them. 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. See more ideas about circuit diagram amplifier circuit.
Power amplifier speaker protection circuit schematic.
If an auxiliary supply is used it needs to be around 12v to suit the relay coils. The output of the power amplifier connects to the speakers directly. This current may damage the speaker especially in case of direct coupled amplifier. Designed for 300w 500w high power amp 220v soft stary line speaker with dc protection circuit and dc rectification section.
