Operating Voltage
The PRE preamplifier is factory-set for 100V, 120V, 220V, or 240V AC mains
operation at either 50 or 60Hz, according to the country for which the unit
was manufactured. (230V/50Hz only in European Union countries, in compli-
ance with CE regulations.) Make sure that the label on the rear panel of the
PRE indicates the correct AC operating voltage for your location. The operat-
ing voltage cannot be changed by the user, and any attempt to do so will void
the warranty.
If the voltage indicated is incorrect relative to that supplied in your area, see
your Proceed dealer.
