serial number e serial number for your power amplifi er is found on the rear of the unit.
Please note and record this number on the page entitled Important Safety
Instructions for your future reference.
register your purchase! Having found the serial number, now would be a good time to fi ll out the
registration card. Please register your purchase so we can advise you of updates

operating voltage e CA-3200 power amplifi er is set at the factory (internally) 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). e voltage setting may not be changed by the user or dealer.
Make sure that the label on the rear panel of your power amplifi er indicates
the correct AC operating voltage for your location. Attempting to operate your
power amplifi 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 power amplifi er is incorrect, please
contact your local, authorized Classé dealer or distributor.
e CA-3200 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.
e CA-3200 includes protection circuitry that will prevent the amplifi 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 amplifi 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 amplifi er will enter
protection mode and shut down. 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 amplifi er will continue to play (since this does
not present a particular danger to the amplifi er), but note that
it may not be able to achieve its usual standard of performance
under these compromised conditions. e Standby LED will fl ash
to indicate the condition.
