E PROTECTION CIRCUITRY

There are no fuses in the KST-100The. amplifier is

protectedbya series of non-intrusive,opto-c_o,upled circuits that constantly evaluate the amplifier s operation.

Appropriateprotective action exists for DCconditions, short circuit, oscillation, ACpoweranomalies,high

groundresistance and out-of:phase ground. Collectively the protection circuitry is designedto avoid damageto

the amplifier or speal~ers causedby othe.r defective com- ponents, faulty wiring, mishandlingof tlae systemor amplifier failure. Whenthe protection circmt is engaged,

the a.mplifier will shut off andshort its output. After resolving either the input or output problemthe amplifier can be turned on.

Theamplifier also has a circuit breaker type powe.r switch that protects it fromexcessive ACcurrentdraw.

Shouldthe breaker shut off frequently or becomedifficult to push ONcontact your dealer or Krell Industries.
