Caution!

•DO NOT place the Nº33H on a thick rug or carpet or cover the Nº33H with a cloth, as this might prevent proper cooling.

•DO NOT expose the Nº33H to high temperatures, humidity, steam, smoke, dampness, or excessive dust. Avoid installing the Nº33H near radiators and other heat-producing appliances.

Note

Each Nº33H dissipates about 360 watts of heat energy when idle; it is normal and safe for it to run warm.

Power Requirements

When shipped, the Nº33H 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 Nº33H, 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.

Your Mark Levinson Nº33H Monaural Power Amplifier is charac- terized by its remarkable ability to pass a musical signal with utter integrity, regardless of how demanding that signal and the loud- speakers used might be. When called upon to do so, the Nº33H is capable of generating truly prodigious power levels into almost any speaker load, on either an instantaneous or a continuous basis.

Depending on the demands placed on the Nº33H by your loud- speaker and your listening habits, it is possible for the quality and current capability of your electrical service to become the limiting factor in the performance of your system.

In this case, consider installing a dedicated AC circuit for your amplifiers. Contact a licensed electrician for assistance. 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.
