Classe Audio CA-D200 owner manual Event log

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 Output 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 — (Does not apply to CA-D200) The power supply has reached the limits of the amp’s safe operating range.

•Air intake filter — (Does not apply to CA-D200) 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 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.
