3Remote Control Output

0Digital Output: Connect this jack to the coaxial or optical digital input of an external digital-to-analog converter for direct access to the digital signals of the CD player or the external digital audio source. DO NOT connect this jack to the standard audio inputs of any device.

1Audio Outputs: Connect these jacks to the CD audio inputs of your receiver, surround processor or preamplifier. If your amplifier features balanced XLR inputs, you may use the XLR outputs instead. Sound quality via balanced connection is usually more dynamic, with even better signal-to-noise ratio. Pin configuration for the XLR Outputs: Pin 1 is Ground, Pin 2 is Plus/Hot, Pin 3 is Minus/Cold.

2Remote Control Input: Connect the output of a remote infrared sensor or the remote control output of another compatible Harman Kardon product. This will enable the remote control system to operate even when the front panel remote sensor is blocked. It will also allow use of the CD player with optional, external control systems.

3Remote Control Output: Connect this jack to the input of another compatible Harman Kardon remote-controlled device to have the remote sensor on the CD player provide signals to other products.

4AC Power Cord: Connect this plug to an AC outlet. If the outlet is switch-controlled, make certain that the switch is in the On position.

5Coaxial and Optical Digital Inputs: Connect these jacks to the coaxial or optical digital output of an external audio source. This will enable you to have the digital-to- analog conversion of that source done by the highgrade audiophile digital-to-analog convertors in the HD 990 rather than the (older ones) in the external source, for better audio quality.

6HRS-Link Output: The special High-Resolution Synchronization Link cable (optional) connects to the HRS jack on the matching HK 990 amplifier (or other compatible HK amplifiers) to attain an even higher quality of sound. You need only connect the HRS-Link cable for complete synchronization and audio. No further cable is necessary.
