Dual Monaural Power Amplifiers Operating Manual N 333 N 332 N 331

Operating Voltage,

Nº332 & Nº331

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.)
