operating voltage Th e CP-500 preamplifi er 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).
Th
e voltage setting may not be changed by the user.
Make sure that the label on the rear panel of your preamplifi er indicates the
correct AC operating voltage for your location. Attempting to operate your
preamplifi er at an incorrect voltage may damage the unit.
Warning: 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 preamplifi er is incorrect, please
contact your local, authorized Classé dealer or distributor.
Th e CP-500 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.
Th e CP-500 includes protection circuitry that will prevent the preamplifi er 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 preamplifi er 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 preamplifi er will
enter protection mode and shut down. Th
e Standby LED will
fl ash to indicate the protection mode has been engaged.
• Under-voltage during operation: if the AC mains voltage sags
by 15% or more, the preamplifi er will continue to play (since this
does not present a particular danger to the unit), but note that
it may not be able to achieve its usual standard of performance
under these compromised conditions. Th
e Standby LED will fl ash
to indicate the condition.
