Another benefit of having worked with highly refined circuit designs so extensively over many years is that we have vast experience in what works well over the long term.

By using only the highest quality parts to begin with, and then using them in an informed way as a result of both accelerated aging experiments and actual long- term experience, we are able to design and manufacture products which we are confident will stand the test of time.

We are confident that your new Classé product will give you many years of trouble-free reliability and musical enjoyment, just as previous Classé products have given their owners.

Finally, your new Classé amplifier incorporates a variety of protection circuits, all designed to protect both the amplifier and your loudspeakers against dangerous fault conditions. Significantly, these protection circuits do not intrude upon

or limit the normal performance of the amplifier; rather, they simply put the amplifier into protection mode when confronted with abnormal conditions. These conditions include:

•output overload

•DC offset

•AC mains voltage (outside of normal tolerances)

•excessive operating temperatures

If any such conditions occur (any of which might harm either your amplifier or possibly your loudspeakers), the amplifier will immediately go into protection mode. In such a case, a Channel LED indicator will blink red until the fault can be righted and the amplifier is re-started.

If the fault is not channel-related, e.g. AC mains voltage out of range, the Standby LED will blink. In all cases, the unit will need to be re-started once the cause of the fault condition has been rectified.
