Special Design Features

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.

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.

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.

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, theStandby 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.
