2 TABLE OF CONTENTS
Introduction
Congratulations on your choice of the Harman Kardon HK 675 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 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 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.
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 maintain proper ventilation, make sure there is at least 10 cm of space above and around the amplifier.
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 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.
