application of advanced class D amplier design principles and exhaustive
testing.ToconqueroneofthemostchallengingproblemsinclassDdesign,a

for optimum performance. is unusual accomplishment showcases both the
innovation of the design and the persistence of the Classé Design team.
extensive listening tests Excellent measured performance is to be expected in world-class products, and
Classé products deliver that performance. However, experience has shown that
technical excellence alone is insucient to guarantee subjectively musical results.
For this reason, all Classé products are laboriously ne-tuned during the
development process by carefully controlled listening tests. Our ears are still
some of the nest test instruments available, and nicely complement more
traditional engineering test equipment. We rely on careful listening tests, which
we view as a necessary complement to the solid engineering you should rightly
expect from Classé.
extraordinary longevity e Classé Design team has accumulated 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 tests and actual long-
term experience, we are able to design and manufacture products which we are
condent will stand the test of time.
We are condent that your new Classé amplier 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 amplier incorporates a variety of protection circuits, all
designed to protect both the amplier and your loudspeakers against dangerous
fault conditions. Signicantly, these protection circuits do not intrude upon
orlimitthenormalperformanceoftheamplier;rather,theysimplyputthe
amplier into protection mode when confronted with abnormal conditions.
ese conditions include:
• outputoverloadandshortcircuitprotection
• DCoset
• excessiveoperatingtemperatures
Some conditions, such as DC oset, are corrected automatically in the amplier
while others will result in either the amplier temporarily reducing its output
or, in extreme cases, switching itself o. In such a case, the Standby LED status
indicator will blink red until the fault can be righted and the amplier is reset by
pressing and holding the standby button for at least three seconds.
