Introduction
Congratulations on your choice of the
Harman Kardon HK670 Integrated Amplifier.
Harman Kardon HK670 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.
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.

Protection Circuitry
Harman Kardon's unique protection circuitry
guards the amplifier from short circuit or dam-
aged 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 230V
AC. 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
pressing the round Power button above “Power”
(see page 5). Do not place furniture or other
heavy objects on the cord, and try to avoid drop-
ping 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.

close to heating equipment.
■ Extremely cold locations.
■ Places subject to excessive vibration
■ Places subject to excessive vibration
or dust.
■ Poorly ventilated places.
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.

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, imme-
diately turn the amplifier off and unplug the
power cord. Contact your dealer or nearest
Harman Kardon service center.

of the HK670. Use the white, black or gray
plugs to connect Left channel jacks; use the

Wired Remote Control
To control your amplifier with an external
infrared remote sensor, connect the wire from
the remote sensor to the REMOTE IN jack on the
back panel. Or, if another stereo component has
a built-in infrared remote sensor and a Remote
Output jack, it may be possible to connect this
jack to the REMOTE IN jack of your amplifier. All
Harman Kardon products with »Remote In« and
»Remote Out« jacks are compatible with one
another, except for the Citation 22, 24 and 25.
Other manufacturers' remote sensors and com-
ponents may not be compatible, but it will not
hurt to experiment. A second wire may be used
to connect your amplifier's REMOTE OUT jack to
the Remote Input of another stereo component.

Digital Loop-Through
Digital inputs and outputs are provided only as a
convenience for connecting various digital com-
ponents to the “CD”, “CDR” and “AUX” digital
inputs. The corresponding digital input signal is
fed to the “DIGITAL OUT” connector when
“CD”, “CDR” or “AUX” is selected as input
source, to provide a digital signal for CD or MD
Recorders. The HK670 cannot process, decode or
convert any digital signal.
