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 experi-
ments 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 shut the amplifier down when confronted with dan-
gerous conditions. These conditions include:
• output overload
• clipping
• DC offset
• AC mains voltage (outside of normal tolerances)
• excessive operating temperatures
If any such conditions prevail (any of which might harm either your amplifier
or possibly your loudspeakers), the amplifier will immediately shut itself
down. In such a case, the 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 (low AC mains voltage, for example), the standby LED
will blink.
If you see the Channel LED Indicator blinking red as
described above, please disconnect the amplifier from
the AC mains immediately and check that all external
connections are cleanly made and secure. If no fault is
immediately obvious, please call your local, authorized
Classé dealer for assistance.
