2 TABLE OF CONTENTS

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 distortion 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.

Harman Kardon Hk 970 User Manual

Do Not Open the Cabinet

To prevent shock hazard, do not tamper with internal components for inspection or maintenance. Harman Kardon does not guarantee against performance degradation resulting from any modification. If water, a hairpin or wire accidentally 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.

Connecting Other Components

1.Make sure your amplifier and other components 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 component’s Input/Record jacks to the Output jacks of the HK 970. 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 components 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 components (if compatible).

Connecting Speakers

1.For best performance, use high quality speaker cables. However, ordinary copper wire can be used if the gauge meets the following requirements:

Diameter

Up to 2.5 meter

1 mm

Up to 4 meter

Harman Kardon Platinum Manual

2.Avoid rolling excess wire with or near signal interconnects.

External Power Amplifiers

For applications where higher power is desired, connect the Pre-Out Jacks to the Main In Jacks of an external power amplifier. The level of the output can be adjusted between -3 and +3 dB with an internal button. To adjust the level, gently insert a small screwdriver into the button and turn clockwise to increase or counter-clockwise to decrease the output level.

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 simultaneously except as recommended above. Amplifier may overheat.

AC Power

Plug the cord into a 230 VAC wall socket.

Power indicator will light up to indicate power ON. To completely disconnect the power input, the main plug must be disconnected from the mains.

Independent Remote Control

The system remote of the HK 970 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 HK 970 and external devices that can be controlled by the HK 970 remote.

Important Notes:

To remote control a tuner, 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 distance 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 amplifier. 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 extended period, remove the batteries to prevent damage from corrosion.
