Installation

To prevent possible damage to your speakers and other components in your audio system, it is important that ALL components, including the HD 990 and your receiver or preamp and amplifiers, are turned off and unplugged from their AC power source when installing any new component.

Connecting the HD 990 to your audio system is simple. Using standard RCA-to-RCA interconnect cords or balanced XLR-cables, 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 Coaxial or Optical Digital Output jack  to the Coaxial or Optical Digital input on the decoder. Make certain to use a coaxial-style interconnect cable, as standard audio cables will not perform as well.

If you use the matching Harman Kardon HK 990 amplifier, you may connect it to the HD 990 with the special HRS-Link cable, which transmits both audio and clock-synchronization signals. This very advanced connection rewards you with ultimate sound quality. Simply connect the HRS-Link Output  on the HD 990 to the HRS-Link Input on the HK 990.

If you have additional external audio sources, you might want to connect their coaxial or optical digital output to the Coaxial or Optical Digital Inputs on the rear panel of the CD player. This will enable you to use the audiophile high-grade digital-to-analog converters and processing power in the HD 990 rather than the (older and less powerful) converters of your external source.

Note that to hear the sound from the external source when connected like this, the input of your amplifier or receiver should be the one to which the HD 990 is connected.

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 toward 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 toward 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 HD 990 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 IR-system remote product.

You may also use the IR Sensor in the HD 990 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 HD 990, make certain that it has the compatibility to power a device that draws at least 20 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 for the HD 990 to operate.
