IMPORTANT NOTES REGARDING PROTECTION CIRCUITRY

1.When the Output Protection circuitry has been engaged, allow at least 20 seconds before turning on the amplifier again. Repeated fast cycling of the On/Off switch can damage the amplifier and void the warranty.

2.If the amplifier does not come on following the procedure above, please contact your dealer.

3.There is a circuit breaker on the amplifier real panel. This breaker protects the amplifier in the event of catastrophic failure. If the circuit breaker engages, contact your dealer or the Krell Service Department. Do not attempt to reset the circuit breaker.
