Power Requirements; Operating States - Harman Mark Levinson 534 Manual Del Propietário

INSTALLATION CONSIDERATIONS
o Pair of gloves (for use during unpacking and setup)
o Documentation
CAUTION!: DO NOT attempt to lift or move the power amplifier
without adequate assistance. The shipping weight of the
amplifier exceeds what a single person should lift alone. To
avoid injury or damage to the unit, at least two people are
required to lift or move the amplifier.
Knit gloves with special gripping surfaces on the palms and
fingers are included with the amplifier. Wear these gloves
when lifting or moving the amplifier.
A heavy strap is routed underneath the amplifier and up through the
heat sink fins, allowing two people to more easily lift the amplifier out
of the shipping carton.
PLACEMENT AND VENTILATION
• DO install the power amplifier on its own shelf for proper
ventilation.
• DO install the amplifier chassis on a solid, flat, level surface.
• DO install the power amplifier close to associated components
to keep interconnecting cables as short as possible.
• DO select a dry, well-ventilated location out of direct sunlight.
• DO allow at least 3 to 4 inches (8 to 10cm) of clearance above
and on each side of the amplifier for proper heat dissipation.
• DO allow at least 6 inches (15cm) 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 amplifier chassis 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 chassis or reduce airflow through the amplifier.
• DO NOT place the amplifier chassis 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 power amplifier to high temperatures,
humidity, steam, smoke, dampness, or excessive dust. Avoid
installing near radiators and other heat-producing appliances.

POWER REQUIREMENTS

The amplifier is configured at the factory for 100, 115, or 230 VAC
power operation at 50Hz or 60Hz. Before operating, ensure that the
power label on the rear panel near the AC input connector indicates
the correct operating voltage. A detachable IEC power cable intended
for use in the region where the unit is sold is included.

Connection to an AC voltage other than that for which the unit is
intended can create a safety and fire hazard and may damage the unit.
If you have any questions about the voltage requirements for your
amplifier or about the line voltage in your area, contact your authorized
Mark Levinson dealer before plugging the unit into an AC power outlet.
WARNING!
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 may result in personal
injuries and/or product damage.
You should unplug the amplifier from the AC wall outlet during
lightning storms and extended periods of non-use.
CAUTION: BEFORE moving the unit, make sure it is powered off by removing
the power cord from the AC power outlet and the unit's rear panel.

OPERATING STATES

The amplifier has three operating states:
• Off: The AC mains power is disconnected by using the rear-
panel Power switch or by removing the power cord from the
rear panel.
• Standby: The Standby mode can be configured to one of three
types: Green, Power Save, and Normal.
o Green: This mode removes power from almost all of the circuits,
allowing the unit to be activated only via a 5V – 12V trigger or
a press of the Standby button. This mode provides maximum
power conservation and is the factory-default Standby mode. In
this mode, the LED is dimmed.
o Power Save: This mode removes power from the audio circuits,
but keeps the control circuitry powered and ready to receive
commands. This mode provides moderate power conservation.
In this mode, the LED is dimmed.
o Normal: This mode mutes the audio outputs, but keeps all of its
control and audio circuits powered. This mode provides the least
amount of power conservation but allows the audio circuits to
remain warmed up to deliver optimal performance at all times.
• On: The entire unit is powered up and all outputs are active. The
front panel LED illuminates red steadily when the unit is on.
When Green or Power Save are selected, the amplifier also engages
its Auto Off function that automatically places it into Standby after
20 minutes of no audio signal or control input. You can bypass Auto
Off by selecting Normal standby or supplying 12V DC to the Trigger
Input from a preamplifier or other component in the system. For more
information on changing settings of the amplifier, please see the
Settings section of this manual.
