OPERATION
PROTECTION CIRCUITRY
There are no fuses in the KSA. The amplifier is protected by a series of non-
intrusive, | that constantly | evaluate | the | amplifier's | ||||||
operation. | Appropriate | protective | action | exists | for | DC conditions, | short | |||
circuit, | oscillation, | ACpower anomalies, | high ground resistance | and | ||||||
phase ground. Collectively, | the | protection | circuitry | is | designed | to avoid |
damage to | the amplifier or speakers | caused by other | defective | components, | ||||||
faulty wiring, | mishandling | of | the | system | or | amplifier | failure. | When the | ||
protection | circuit | is engaged, | the | amplifier | will | shut | off | and short | its output. |
The amplifier can be turned on after resolving either the input or output problem.
SIMPLE TROUBLE-SHOOTING STEPS
Follow these steps when trying to resolve the cause of potential amplifier related failure. If the amplifier will not turn on, or stay on:
1.Disconnect all input and output connections. Once this is completed, try turning the amplifier on.
If the amplifier does not come on, check the circuit breaker on the back panel. If the circuit breaker has popped out or appears to be more extended than usual, reset the breaker switch by pressing it back in. If the amplifier still does not come back on, call KRELL.
If the amplifier does not come on and the circuit breaker on the back of the unit seems normal, check the house circuit breaker or fuse for the power outlet associated with the amplifier.
NOTE:When turning the amplifier on and off between cable checks, let the amplifier settle for at least 45 seconds before turning it back on.
2.If the amplifier turns on and appears to work properly again, turn the amplifier off and reconnect the output speaker cables for one channel only.
If the amplifier turns on normally, reconnect the other channel output speaker cables.
