PA 2000 (serv.man6) - Harman Kardon Audio User Guide / Operation Manual. Page 4

INTRODUCTION

Verify Line Voltage Before Use
Your new Harman Kardon PA 2000 amplifier has
been factory-configured for use with 220/240-volt
AC line current. Connecting the amplifier to a line
voltage other than that for which it is intended
can create a safety and fire hazard, and may dam-
age the amplifier.

If you have any questions about the voltage
requirements for your specific model, or about the
line voltage in your area, contact your selling
dealer before plugging the unit into a wall outlet.

Verify AC Circuit Capacity Before Use 
High-power output of your amplifier may require
heavy current draw under full load conditions. To
ensure proper performance and avoid potential
safety hazards, we recommend that it be connect-
ed to a circuit with min. 10-amp capacity.
Connecting multiple amplifiers to the same cir-
cuit, or connecting the amplifier to a circuit used
by other heavy-power devices, such as high-
wattage lights, may cause circuit breakers to trip.
It is always a good idea to avoid using any audio
equipment on the same AC circuit as equipment
with motors, such as air conditioners or refrigera-
tors. This will lessen the possibility of power varia-
tion and electrical start-up noise affecting your
sound system.

Do Not Use Extension Cords
To avoid safety hazards, use only the power cord
supplied with your unit. If a replacement cord is
used, make certain that it is of a similar gauge.
We do not recommend using extension cords
with this product. As with all electrical devices, do
not run power cords under rugs or carpets or
place heavy objects on power cords. Damaged
power cords should be replaced immediately with
cords meeting factory specifications.

Handle the AC Power Cord Gently
When disconnecting the power cord from an AC
outlet, always pull the plug; never pull the cord. If
you do not intend to use the amplifier for a con-
siderable length of time, disconnect the plug from
the AC outlet.

Do Not Open the Cabinet
There are no user-serviceable components inside
this product. Opening the cabinet may present a
shock hazard, and any modification to the product
will void your guarantee. If water enters the unit,
or any metal object such as a paper clip, wire or
staple accidentally falls inside the cabinet, discon-
nect the unit from the AC power source immedi-
ately and consult an authorized warranty station.

Installation Location
■ To ensure proper operation and to avoid the

potential for safety hazards, place the unit on
a firm and level surface. When placing the
unit on a shelf, be certain that the shelf and
any mounting hardware can support the
amplifier’s weight.

■ Make certain that the proper space is provided

both above and below the unit for ventilation.
If the amplifier will be installed in a cabinet or
other enclosed area, make certain that there
is sufficient air movement within the cabinet.
Consult with your dealer or installer for more
information.

■ Do not place the unit directly on a carpeted

surface.

■ Avoid installation in extremely hot or cold

locations, in an area that is exposed to direct
sunlight or near heating equipment.

■ Avoid moist or humid locations.

■ Do not obstruct the ventilation slots on the

top of the unit or place objects directly over
them. Remember, power amplifiers generate
heat, and the heatsink fins and ventilation
slots that form part of the cabinet are special-
ly designed to remove this heat. Placing other
electronic equipment near these heat-dissipa-
tion systems may possibly affect the long-
term reliability of both your amplifier and the
objects placed above it.

Cleaning
When the unit gets dirty, wipe it with a clean, soft
and dry cloth. If necessary, first wipe the surface
with a soft cloth slightly dampened with mild
soapy water, followed by a fresh cloth with clean
water. Wipe immediately with a dry cloth. Never
use benzene, thinner, alcohol or any other volatile
cleaning agent. Do not use abrasive cleaners, as
they may damage the finish of metal parts. Avoid
spraying insecticide near the unit.

Moving the Unit
Before moving the unit, be certain to disconnect
any interconnection cords with other components,
and make certain that you disconnect the unit
from the AC outlet.

The carton and shipping materials used in pro-
tecting your new amplifier were specially
designed to cushion it from the shocks and vibra-
tion of shipping. We suggest that you save the
carton and packing materials for use in shipping if
you move or if the unit ever needs repair.

To minimize the size of the carton in storage, you
may wish to flatten it. Carefully remove any sta-
ples used to close carton seams; carefully slit the
tape on the bottom and collapse the carton.
Other cardboard inserts may be stored in the
same manner. Packing materials that cannot be
collapsed should be saved along with the carton
in a plastic bag.

When positioning the amplifier in its final loca-
tion, make certain that it has adequate ventilation
on all sides, as well as on the top and bottom. Do
not place CDs, record jackets, owner’s manuals or
other paper on top of or beneath the unit or in
between multiple amplifiers in a stack. This will
block the air flow, causing degraded performance
and a possible fire hazard. If the unit is to be
enclosed in a cabinet or rack, make certain that
there is adequate air circulation, with means pro-
vided for hot air to exit and for cool air to be
brought in.
