Operating Voltage
The PAV preamplifier is factory-set for 100V, 120V, 200V, 220V, or 240V AC
mains operation at either 50 or 60Hz, according to the country for which the
unit was manufactured. (230V only in European Union countries, in compli-
ance with CE regulations.) Make sure that the label on the bottom of the PAV
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 what is supplied to your area, see your
Proceed dealer.
