ProtectLEDS
Red LED indicates that the amp channel is in Protect mode. During Power up,
the amp briefly goes into protect mode in order to prevent any loud speakers
from being overloaded / exhausted by the speakers. After a few seconds the
ampcomesoutofprotectmodeandis ready fornormaloperation.If theamp
staysinProtectmode,thisindicatesthattheremaybeaprobleminternal
to the amp. If the amp goes into Protect mode during operation this indicates
that either a problem has occurred internally to the amp or the amp is being
overloaded/exhaustedandneedstocooldown.AfteraProtectcondition,the
