DO allow at least 6 inches (15.24cm) of clearance behind the

amplifier so that the power cord and cables have space to bend

without becoming crimped or strained.

DO NOT place the Nº53 on a thick rug or carpet or cover the

amplifier with a cloth, as this might prevent proper cooling.

DO NOT obstruct the ventilation holes on the top and bottom of

the unit or reduce airflow through the Nº53.

DO NOT place the Nº53 near low-level components. The power

amplifier is capable of producing large output currents and hence

significant magnetic fields, which can induce noise in sensitive

components.

DO NOT expose the Nº53 power amplifier to high temperatures,

humidity, steam, smoke, dampness, or excessive dust. Avoid

installing near radiators and other heat-producing appliances.

Warning!

MAKE SURE all components are properly grounded. Do not

defeat the safety purpose of polarized or grounding-type plugs

with “ground-lifter” or “cheater” adapters. Doing so may cause

dangerous voltage to build up between components, which can

result in personal injuries and/or product damage.

Power Requirements

The Nº53 Reference power amplifier is configured at the factory for

100, 120, or 230 VAC power operation at 50Hz or 60Hz. Before

operating the Nº53, ensure that the voltage label on the rear panel

near the AC input connector indicates the correct operating voltage.

Caution! DO NOT attempt to adjust the operating voltage. Consult a Mark

Levinson dealer if the operating voltage is incorrect or must be

changed for relocation purposes.

Different operating voltages may require the use of different

power cords and/or attachment plugs. Contact a Mark Levinson

dealer for additional assistance.

The Nº53 is capable of passing remarkable sound at exceptional

power levels. Depending on listening habits, loudspeaker demands,

and the number of power amplifiers present in the system, it is

possible that the electrical service may become the limiting

performance factor of your home theater system.
