Special Design Features
highly refined
circuit design
This Classé amplifier benefits from the use of high quality component parts,
application of advanced class D amplifier design principles and exhaustive
testing. To conquer one of the most challenging problems in class D design, a
dead-band time minimization algorithm is initiated at turn-on to ensure the
lowest possible distortion; consequently, less overall negative feedback is required
for optimum performance. This 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 insufficient to guarantee subjectively musical results.
For this reason, all Classé products are laboriously fine-tuned during the
development process by carefully controlled listening tests. Our ears are still
some of the finest 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
The 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
confident will stand the test of time.
We are confident that your new Classé amplifier 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 and short circuit protection
• DC offset
• excessive operating temperatures
Some conditions, such as DC offset, are corrected automatically in the amplifier
while others will result in either the amplifier temporarily reducing its output
or, in extreme cases, switching itself off. In such a case, the
Standby LED
status
indicator will blink red until the fault can be righted and the amplifier is reset by
pressing and holding the standby button for at least three seconds.
