The CAP-2100 integrated amplifier is set at the factory for 100V, 120V, 220V, 230V, or 240V AC mains operation, as appropriate for the country in which it is to be sold (230V only in European Union countries, in compliance with CE regulations.) The voltage setting may not be changed by the user.
Make sure that the label on the rear panel of your power amplifier indicates the correct AC operating voltage for your location. Attempting to operate your power amplifier at an incorrect voltage may damage the unit.
The voltage setting of your power amplifier may not be changed by the user. There are no user-serviceable parts within the unit. Please refer any problems to an authorized Classé service center.
If the AC mains voltage indicated on your integrated amplifier is incorrect, please contact your local, authorized Classé dealer or distributor.
The CAP-2100 can easily be powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account.
The CAP-2100 includes protection circuitry that will prevent the integrated 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.
