INTRODUCTION 3

Introduction

Congratulations on your choice of the

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.

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 avail-

able 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 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.

Place of installation

Place the unit on a firm and level surface. Avoid

installing your unit under the following condi-

tions:

■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.

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.

Packaging

Save all packing material. It is essential for ship-

ping, should you move, or in the event the unit

ever needs repair.

4CONNECTIONS

Connections

Connecting Other Components

1. Make sure your amplifier and other compo-

nents are turned off.

2. Connect each component's Output/Play jacks

to the corresponding Input jacks on the back

of your amplifier and, if available, the compo-

nent’s Input/Record jacks to the Output jacks

of the HK670. Use the white, black or gray

plugs to connect Left channel jacks; use the

red plugs for Right channel jacks.

3. A record player with MM cartridge must be

connected to the Phono Input jacks and a

separate ground wire to the ground terminal

screw above.

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.

Continue this process to include additional com-

ponents (if compatible).

Connecting Speakers

1. For best performance, use high quality speak-

er cables. However, ordinary copper wire can

be used if the gauge meets the following

requirements:

Wire Min.

Length Diameter

Up to 2.5 meter 1 mm

Up to 4 meter 1.25 mm

Up to 6 meter 1.6 mm

Above 6 meter 2-2.5 mm

2. Avoid rolling excess wire with or near signal

interconnects.

IMPORTANT: When connecting two pairs of

speakers, determine the impedance of each pair

by looking on the back of the speakers, in your

owner's manual, or by contacting your dealer or

manufacturer.

You can listen to two pairs of speakers at

the same time ONLY if the impedance of

EACH speaker is NOT LESS THAN 8 Ohms.

WARNING: Do not play sets of speakers simul-

taneously except as recommended above. Ampli-

fier may overheat.

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.

6REMOTE CONTROL

Remote Control

Independent Remote Control

The system remote of the HK670 can control the

amplifier and compatible Tuners, CD Players and

CD Recorders. The remote In jack of units without

an integrated IR receiver must be connected to

the amplifier's remote control output jack so that

the system remote control can operate them.

The Function Table below will show all functions

of the HK670 and external devices that can be

controlled by the HK670 remote.

Important Notes:

• For controlling a tuner (only needed for the

numeric buttons), CD Recorder or CD Player

the appropriate input ("TUNER", "CDR" or

"CD") must have been selected with the

source buttons of the remote control (selecting

on the front panel is not sufficient).

• Note that DVD players or tape decks cannot

be controlled by the remote.

• To control a compatible CD Recorder "CDR"

must be selected as input and the drive to be

controlled (CDP or CDR) must be selected

appropriately with the "CDP SELECT" or "CDR

SELECT" buttons.

Operating Conditions

The control unit operates effectively within a dis-

tance of 7 meters and an angle of 30° from the

amplifier. Using the control near fluorescent

lights may shorten this range, as will any dust or

dirt that accumulates on the front of the remote

control or the remote sensor area of the amplifi-

er. Also avoid blocking the line of sight between

amplifier and remote.

The control unit is powered by two AA batteries,

included with your amplifier. When you replace

weak batteries, replace both at the same time.

When the remote is to be unused for an extend-

ed period, remove the batteries to prevent dam-

age from corrosion.
