Information

Important Safety Information

Verify Line Voltage Before Use

Your HD750 has been designed for use with 230-volt AC current. Connection to a line voltage other than that for which it is intended can create a safety and fire hazard, and may damage the unit.

If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet.

Do Not Use Extension Cords

We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on them. Damaged power cords should be replaced immediately by an authorized service depot with cords meeting factory specifications.

Handle The AC Power Cord Gently

When disconnecting the power cord from an AC outlet always pull the plug, never pull the cord. If you do not intend to use the unit for any considerable length of time, disconnect the plug from the AC outlet.

Do Not Open The Cabinet

Moving The Unit

Before moving the unit, be certain to disconnect any interconnection cords with other components, and make certain that you disconnect the unit from the AC outlet.

Unpacking

The carton and shipping materials used to protect your new HD750 during shipment were specially designed to cushion it from shock and vibration.We suggest that you save the carton and packing materials for use in shipping if you move or should the unit ever need repair.

To minimize the size of the carton in storage, you may wish to flatten it. This is done by carefully slitting the tape seams on the bottom and collapsing the carton down to a more twodimensional appearance. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag.

If you do not wish to save the packaging materials, please note that the carton and other sections of the shipping protection are recyclable. Please respect the environment and discard those materials at a local recycling center.

CAUTION: The HD750 uses a laser system. To prevent direct exposure to the laser beam, do not open the cabinet enclosure or defeat any of the safety mechanisms provided for your protection. DO NOT STARE INTO THE LASER BEAM. To ensure proper use of this product, please read this owner’s manual carefully and retain it for future use. Should the unit require maintenance or repair, please contact your local Harman Kardon service station. Refer servicing to qualified personnel only.

8 REMOTE CONTROL FUNCTIONS

Installation

To prevent possible damage to your speakers and other components in your audio system, it is important that ALL components, including the HD750 and your receiver or preamp and amplifiers, are turned off and unplugged from their AC power source when installing any new component.

Connecting the HD750 to your audio system is simple. Using standard RCA-to-RCA interconnect cords, connect the left and right Audio Output jacks ™ on the rear panel to the CD input jacks on your receiver, surround processor or preamplifier.

If your system includes an optional external digital-to-analog converter, or if you are using a receiver or other processor that has the capability to decode PCM digital input signals, connect the Digital Output jack ¡ to the Coaxial Digital input on the decoder. Make certain to use a coaxial-style interconnect cable, as standard audio cables will not perform as well.

Install two AA batteries by turning the remote over so that you are holding the bottom side up. Press lightly on the embossed arrow on the cover and gently slide the cover towards you in the direction of the arrow. Insert the batteries inside the compartment, being careful to follow the + and – polarity indications at the bottom of the compartment. Replace the cover by placing it on the remote and sliding it back towards the top of the remote.

➞

NOTE:When replacing batteries, always replace both at the same time.When the unit will not be used for an extended period of time, it is also a good idea to remove the batteries so that the potential for corrosion or damage is avoided.

If the HD750 is installed behind a cabinet or other obstruction that may block the path between the front-panel Remote Sensor and the location of the remote, an optional external IR sensor may be used. Connect the sensor to the Remote IR-In Jack £ on the rear panel. This jack may also be connected to the IR-Output jack of another compatible Harman Kardon component or a compatible IRsystem- remote product.

You may also use the IR Sensor in the HD750 to send commands to other compatible remote controlled products. Connect the Remote IR- Out jack ¢ to the input of the other product or system.

Connect the power to a nonswitched AC wall outlet or to the accessory outlet on the rear of another audio device in your system and you are ready to go!

NOTE:When using the accessory outlet on another product to power the HD750 make certain that it has the compatibility to power a device that draws at least 14 watts of current in addition to being able to handle the requirements of the other devices that may be plugged into the accessory outlets. If you use a “switched” outlet, it is important to remember that the host product must be turned on in order for the HD750 to operate.

Disc Handling Notes

When loading or unloading discs, it is best to hold them by the edges.

While Compact Discs are very reliable, rough handling may damage them.Avoid scratching the bottom (non-printed) side of discs, or any handling which will leave fingerprints.

To avoid damage to the disc and player, always seat discs so that they are centered in the tray.

Do not lift the player while the disc tray is opening or closing, as this may cause the disc to unseat from the tray and possibly jam.

, HDCD

HDCD®, which stands for High Definition Compatible Digital that enables the HD750 to deliver outstanding digital-to-analog decoding no matter what type of CD is played.

When a disc with the HDCD logo is played, the HD750 is able to take advantage of the special recording process that is used in the creation of HDCD discs.Although HDCD discs are playable on any CD player, when they are played on a unit such as the HD750, the special circuitry delivers audio with extraordinary fidelity,stunning resolution and the highest possible overall quality.The HDCD process effectively cancels the additive distortions, caused by artifacts of the A/D and D/A conversion processes, and simultanously provides additional data to reduce the subtractive distortions resulting from insufficient data present in the 44.1 kHz, 16-bit PCM sampling standard of the compact disc format.

No special adjustment is required to play an HDCD disc. Simply play the disc as you would any other CD, and the HD750 will automatically sense that it is an HDCD recording. The HDCD
