extraordinary longevity 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.

robust protection 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 of the ﬁrst three conditions occurs on either channel

(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, indicating the channel with the fault, and the sound will be
muted until the fault can be righted.

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.
