Introduction
Congratulations
on your choice of the
Harman Kardon HK 970 Integrated Amplifier.
In order to obtain the best performance from
this integrated amplifier, please be sure to read
this owner's manual and use your integrated
amplifier only in accordance with its instructions.
The special features of this unit include:
HCC
(High Instantaneous Current Capability)
The amplifier sections react rapidly to musical
transients, providing the instantaneous current
necessary to precisely drive and control nearly
any loudspeaker system.
Ultrawide Bandwidth
The bandwidth of this unit is exceptionally wide
and is independent of negative feedback. This
improves transient accuracy and phase linearity.
Low Negative Feedback
This unit has been designed to have low distor-
tion and wide bandwidth without high negative
feedback. This further improves its dynamic
accuracy.
Discrete Component Circuitry
In order to achieve the above goals, all discrete
electronic circuitry has been employed. No
available integrated circuits could provide this
high level of performance.
Sophisticated Electronic
Protection Circuitry
Harman Kardon's unique protection circuitry
guards the amplifier from short circuit or
damaged speakers and wires, without impairing
sound quality by the use of current limiting or
output relays.
General instructions
Always Use at 230V AC
This unit is designed for operation with 230VAC.
Use only domestic AC outlets. Connecting the
unit to an outlet supplying a higher voltage may
create a fire hazard.
Handle the Power Cord Gently
Do not disconnect the plug from the AC outlet
by pulling the cord; always pull the plug itself.
Pulling the cord may damage it. If you do not
intend to use your unit for any considerable
length of time, turn the unit off completely by
taking the power cord out of the AC wall outlet.
Do not place furniture or other heavy objects on
the cord, and try to avoid dropping heavy
objects on it. Also do not tie a knot in the power
cord. Not only may the cord be damaged, it can
also cause a short circuit with a consequent fire
hazard.
Place of installation
Place the unit on a firm and level surface.
Avoid installing your unit under the following
conditions:
■
Moist or humid places.
■
Places exposed to direct sunlight or
close to heating equipment.
■
Extremely cold locations.
■
Places subject to excessive vibration
or dust.
■
Poorly ventilated places.
Provide sufficient ventilation, do not block
ventilation openings.
Do not obstruct the ventilation slots on the top
surface of the unit by placing objects on them.
Otherwise, the temperature inside the unit may
rise, possibly affecting its long-term reliability.
To ensure sufficient ventilation, the product
should be placed in an open area with free air
flow.
Do not place a CD player or other equipment
on top of the amplifier.
Do not expose the amplifier to dripping or
splashing. Do not place objects filled with liquids,
such as vases, on or near the amplifier.
Moving the Unit
Before moving the unit, be sure to pull out the
power cord from the AC outlet and disconnect
the interconnection cords with other units.
Do Not Open the Cabinet
To prevent shock hazard, do not tamper with
internal components for inspection or mainte-
nance. Harman Kardon does not guarantee
against performance degradation resulting from
any modification. If water, a hairpin or wire acci-
dentally enters the unit, immediately pull the
plug from the AC outlet to prevent shock and
consult an authorized Harman Kardon service
station. If you use the unit under this condition,
it may cause a fire shock hazard.
Cleaning
If the unit gets dirty, wipe it with a soft dry cloth.
If necessary, wipe it with a soft cloth dampened
with mild soapy water and then with a dry cloth.
Never use benzene, thinner, alcohol or other
volatile agents, and avoid spraying an insecticide
near the unit.
Warning Signs
If you detect an abnormal smell or smoke,
immediately turn the amplifier off and unplug
the power cord. Contact your dealer or nearest
Harman Kardon service center.
Packaging
Save all packing material. It is essential for
shipping, should you move, or in the event the
unit ever needs repair.
