extraordinary longevity Another benefi t of having worked with highly refi ned 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
confi dent will stand the test of time.
We are confi dent 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 amplifi er incorporates a variety of protection circuits, all
designed to protect both the amplifi er and your loudspeakers against dangerous
fault conditions. Signifi cantly, these protection circuits do not intrude upon
or limit the normal performance of the amplifi er; rather, they simply put the
amplifi er into protection mode when confronted with abnormal conditions.
ese conditions include:
• output overload
• DC off set
AC mains voltage (outside of normal tolerances)
excessive operating temperatures
If any of the fi rst three conditions occurs on either channel (any of which
might harm either your amplifi er or possibly your loudspeakers), the amplifi er 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 rectifi ed.
