Operating Voltage
This Proceed amplifier is factory-set for 100V, 120V, 220V, or 240V AC mains op-
eration at either 50 or 60 Hz, according to the country for which the unit was
manufactured. (230V in European Union countries, in compliance with CE regu-
lations.) Make sure that the label on the rear panel of the amplifier indicates the
correct AC operating voltage for your location. The operating voltage cannot be
changed by the user, and any attempt to do so will void the warranty.
If the voltage indicated does not match the service in your area, see your Pro-
ceed dealer.
Note the serial number While you are checking the voltage, it would probably be a good idea to make a
record of the serial number for your amplifier. This can be found on the label
found on the bottom of the amplifier.
