Your Mark Levinson Dual Monaural Power Amplifier is characterized by its re-
markable ability to pass a musical signal with utter integrity, regardless of how
demanding that signal and the loudspeakers used might be. When called upon to
do so, your amplifier is capable of generating truly prodigious power levels into
virtually any speaker load, on either an instantaneous or a continuous basis.
Depending on the demands placed on your amplifier by your loudspeaker and
your listening habits, it may use a significant portion of the total current capabil-
ity of a standard, 15 ampere household AC mains circuit. Fortunately, most instal-
lations do not require special attention be paid to the AC mains service. If you
have multiple, powerful amplifiers such as you new Mark Levinson amplifier, or
other appliances on the same circuit that use significant current, you may want to
consider having a dedicated AC line installed for your home entertainment sys-
tem.
For compatibility with existing household outlets, a standard three conductor, 15
ampere, IEC-standard, detachable AC mains cable is provided for use with your
amplifier.
Mark Levinson power amplifiers may be factory-set for 100V, 120V, 200V, 210V,
220V, 230V or 240V AC mains operation at either 50 or 60Hz, based on the coun-
try for which they are manufactured. Depending on local electrical codes and
regulations, the plug on the supplied AC input module may need to be replaced
by a local, licensed electrical contractor. The maximum current requirements at
these various voltages under various test conditions are listed in the tables shown
below. (Note that only 230V units are sold in the European Union countries, per
CE requirements.)
