The CA-M400 includes protection circuitry that will prevent the amplifier from operating at dangerously high or low voltages.

•At startup: the AC mains voltage must be within a range of approximately -15% to +10% of its nominal value at startup, or the amplifier will not turn on. For example, a 120V unit requires the AC mains to be between approximately 95V–135V in order to turn on.

•Over-voltage during operation: if the AC mains voltage surges by roughly 10% or more during operation, the amplifier will enter protection mode and shut down. The Standby LED will flash to indicate the protection mode has been engaged.

•Under-voltage during operation: if the AC mains voltage sags by 15% or more, the amplifier will continue to play (since this does not present a particular danger to the amplifier), but note that

it may not be able to achieve its usual standard of performance under these compromised conditions. The Standby LED will flash to indicate the condition.

Your new Classé power amplifier will deliver outstanding performance immediately. However, you should expect to hear it improve somewhat as it reaches its normal operating temperatures and its various components “break-in.” It has been our experience that the greatest changes occur within the first 300 hours, as the amplifier reaches thermal equilibrium and the capacitors fully form. After this initial break-in period, the performance of your new product should remain quite consistent for years to come.

The only exception to this rule is if the unit is placed in standby or unplugged for an extended period of time, allowing it to cool down. Depending on the degree of cooling involved, you should expect a brief warm-up period before the power amplifier’s sound quality is at its best. Unless your amplifier was allowed to become quite chilled, subsequent thermal re-stabilization should not take long. Fortunately, you should never have to repeat the initial 300 hour break-in period.

Please take a few minutes to review this manual, and to familiarize yourself with your new amplifier. We understand that you are anxious to plug everything in and get started. However, reading this manual and following the advice it gives will ensure that you get all the benefits you deserve from having purchased such a fine piece of equipment.
