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.

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 9 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.

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.

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
