SPEAKER PROTECTION (STEREO)
Categories : Series 6 Audio Equipment ,  Speaker Protection , 
This unit is designed to protect loud speakers attached to a stereo OCL (Output Capacitor Less) amplifier. If an OCL amplifier has no in-built protection circuit, a short circuit in its output transistors will allow an uncontrolled DC current though the attached loudspeaker causing it to burn out. The two channel FK650 is designed to detect such a condition and disconnect the speaker before damage can occur.
