Operating Voltage
Your Mark Levinson Nº33 Reference Monaural Power Amplifier is characterized by
its remarkable 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, the Nº33 is capable of generating truly prodigious power levels
into virtually any speaker load, on either an instantaneous or a continuous basis.
its remarkable 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, the Nº33 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 the Nº33 by your loudspeaker and your
listening habits, it is possible for the quality and current capability of your electri-
cal service to become the limiting factor in the performance of your system.
Given its status as a Reference product, any such limitation (even if only rarely
encountered) is unacceptable. As a result, the Nº33 has been designed to be ca-
pable of taking advantage of dedicated high current AC mains supplies which
cannot limit its performance. The Nº33 may be ordered in either a High Current
(HC) or an Ultra High Current (UHC) configuration, depending on the require-
ments of any given installation. (Due to CE regulations, only the UHC, 230V ver-
sion of the Nº33 is available in European Union countries.)

The UHC configuration of the Nº33 accepts a dedicated high voltage (200–240
volts, depending on the country), high current (30–35 amperes, depending on
local electrical codes) AC power source. These high current lines are commonly
used in residential construction for electric stoves, clothes driers, and other de-
manding appliances, making their installation fairly routine for any electrical con-
tractor… although this may be the first time your contractor has installed such
lines for a stereo system!

Important:
When it comes to high voltage/high current AC wiring such as
the Nº33 may use, building regulations and electrical codes
vary from region to region, and even from one municipality to
the next. For this reason, it is impossible for us to anticipate the
requirements of your area with regard to high current AC
hookups. Please review this section carefully and then
contact a local electrical contractor for advice on
connecting your Nº33 to the AC mains power in your area.

The Mark Levinson Nº33 amplifiers may be factory-set for 100V, 120V, 200V, 210V,
220V, 230V or 240V AC mains operation at either 50 or 60Hz. 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 cur-
rent requirements at these various voltages under various test conditions are
listed in the table shown on the next page.
