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 preamplifier indicates the
correct AC operating voltage for your location. Attempting to operate your
preamplifier at an incorrect voltage may damage the unit.
The voltage setting of your preamplifier 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 preamplifier is incorrect, please
contact your local, authorized Classé dealer or distributor.
The CP-700 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 CP-700 includes protection circuitry that will prevent the preamplifier 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 preamplifier 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 preamplifier 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 preamplifier 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.
