only be accessed when the target amplier is in standby. e protection circuit

going into protection and should be referred to in situations that require the
intervention of your dealer or Classé customer support.

• +ve slow blo trip & -ve slow blo trip — e average current has
reached the safe operating limit.
• +ve fast blo trip & -ve fast blo trip — e peak current has
reached the safe operating limit.
