Unpacking and Placement

Carefully unpack your power amplifier according to the supplied instructions, and remove all accessories from the carton. Please take care when lifting the amplifier, as it is quite heavy.

Keep all packing materials for future transport of your Classé product. Shipping your new component in anything other than its purpose-designed packing material may result in damage that is not covered by the warranty.

There are two options when placing your power amplifier: you may place it close to the speakers, requiring longer interconnecting cables from the preamplifier; or place it close to the preamplifier, requiring longer speaker cables.

Although either approach will yield excellent performance, you might consider the first option for two reasons. First, signal quality degrades more easily when transmitted as a combination of both high voltage and high current, suggesting that speaker cables should be kept as short as practical. Second, high quality amplifiers use massive power supplies which inevitably radiate some degree of magnetic fields. Ideally, one would separate these fields from sensitive source components by a reasonable distance.

If it is more convenient for you to place the amplifier in an equipment rack, along with your other components, we suggest placing it at the bottom of the rack, well away from your source components and preamplifier. This location will also be more stable than placing such a heavy component near the top of a rack, which might make it top-heavy.

Note that adequate clearance for the AC cord and connecting cables must be left behind the CA-M400. We suggest leaving eight inches (20 cm) of free space behind your power amplifier to allow all cables sufficient room to bend without crimping or undue strain.

Your Classé power amplifier generates a certain amount of heat in the course of normal operation. Be sure to allow six inches of clearance above it and three inches to each side to allow heat dissipation through air circulation. The vents on both the bottom and the top of the CA-M400 must be kept free from any obstruction which would reduce the flow of air through the unit. Avoid placement on soft surfaces that would restrict airflow (such as plush carpeting).
