Nº433 Power Amplifier
Power Requirements
When shipped, the Nº433 is configured for 100V, 120V, 220V, 230V
or 240V AC power operation at 50 or 60Hz based on the country for
which it is manufactured. Before operating the Nº433, make sure
the ~ac mains connector label indicates the correct operating
voltage for the current location.
Caution! Do not attempt to adjust the operating voltage. Consult an
authorized Mark Levinson dealer if the operating voltage is
incorrect or if the operating voltage must be changed for
relocation purposes.
Be advised that different operating voltages may require the use
of different power cords and/or attachment plugs. Contact an
authorized Mark Levinson dealer for assistance.
The Nº433 is capable of passing remarkable musical signals
regardless of signal and loudspeaker demands. On either an instan-
taneous or continuous basis, this power amplifier can drive
exceptional power levels into most all loudspeaker loads.
Depending on listening habits, loudspeaker demands, and the
number of power amplifiers present in the system – it is possible for
the electrical service to become the limiting performance factor.
In this case, contact a licensed electrician to install a dedicated AC
circuit for the home entertainment system. If more than one AC
circuit is providing power to the system, contact a licensed
electrician to ensure that all components are operating with the
same solid, low-impedance ground reference.
Important Building regulations and electrical codes differ from location to
location, making it impossible to anticipate the requirements of
high-current AC circuits such as the Nº433 is capable of using.
Contact a local, licensed electrician for information.
Warm-up & Break-In
Period
Although the Nº433 delivers superior performance from the first
time it is powered on, this performance will continue to improve as
the power amplifier reaches its normal operating temperature and
various components “break in.” The greatest performance improve-
ments will occur within the first 25 to 50 hours of use. Sound
quality will continue to improve for approximately 300 hours.
After this initial period, performance will remain consistent unless
power is disconnected from the ~ac mains connector. Power is
considered disconnected when the Nº433 is powered off with the
power button
, the power cord is disconnected from the ~ac mains
connector or the electrical outlet, or an extended power failure or
