Amp Info; Event Log - Classe Audio CA-2300 Owner's Manual

amp info Available for amplifiers only, this screen displays the data provided by the
heatsink and AC Module temperature sensors.
NOTE: This feature is only accessible when the target amplifier is on.
event log Reserved for amplifiers, this feature is a protection circuitry event log which can
only be accessed when the target amplifier is in standby. The protection circuit
shuts down the amplifier or channel if it overheats or if its output could damage
your speakers. The event log details the circumstances surrounding the amp
going into protection and should be referred to in situations that require the
intervention of your dealer or Classé customer support.
The log can report the following events interpreted as follows:
• +ve slow blo trip & -ve slow blo trip — The average current has
reached the safe operating limit.
• +ve fast blo trip & -ve fast blo trip — The peak current has
reached the safe operating limit.
• over temperature trip — The unit temperature has reached the
safe operating limit.
• DC protection trip — The DC output level has reached the safe
operating limit.
• Communication failure — There has been a loss of
communication between the amp's system monitoring sensors.
• AC line trip — The power supply has reached the limits of the
amp's safe operating range.
• Air intake filter — The intake filter is constricting airflow and
should be cleaned. This "event" is also triggered after every
2,000 hours of operation, even if the sensors do not yet detect
constricted airflow. The unit will continue to operate with its
standby LED flashing (combined red/blue) until the filter is
checked and the unit reset by pressing and holding the standby
button for 3 seconds.
Events are rare and generally occur due to issues that are external to the amp.
They should be interpreted positively. The amp is doing what it's designed to do.
