FK649

This unit is designed to protect loud speakers attached to OCL amplifiers. If an OCL has no in-built protection circuit, a short circuit in its output transistors will allow an uncontrolled DC current through the attached speaker causing it to burn out.The FK649 is designed to detect such a short-circuit condition and disconnect the speaker before damage can occur.
