Right Loudspeaker output, System 1. ? RS-232 connector for possible future PC update. Update Switch. ? Input jacks for one or two subwoofer signals from external surround processor. ? Output jacks for two subwoofers. ? Digital coaxial output jack for digital record- ing. Also permits digital recording of analog sources. ? Preamplifier output jacks. ? Analog output jacks for tape recording. ? Analog output jacks for CD Recorder analog recording. ? AUX input jacks, suitable for analog signals from video games, video recorders etc. ?TV input jacks for analog sound input from your TV. ?TAPE input jacks for analog tape replay. ? CDR input jacks, for CD Recorder analog replay. ? Balanced analog inputs (XLR), for use with all signal sources that output balanced signals. Available via the CD Input function only, as an alternative to the unbalanced RCA jacks (Input ?). Pin configuration for the XLR Inputs: Pin 1 is Ground, Pin 2 is Plus/Hot, Pin 3 is Minus/Cold. ? Left Loudspeaker output, System 2. ? Left Loudspeaker output, System 1. ? Power lead AC input. ?TUNER analog Input jacks. ? PROCESSORAnalog Inputs. These Inputs go directly to the power amplifier section of the HK 990, bypassing the Volume and Tone Control. Here you can connect the Front Channel Pre Out L+R signals from an external surround processor, to benefit from the superior power of the HK 990 and control volume from the processor. NOTE: Only use the Processor Input with a device that has its own volume control! ? CD analog Input jacks. You can select either this Input or the Balanced Input as analog Input in the CD Input Setup Mode. ? Phono Input for record player with Moving Magnet (high output and high impedance) or High-Output Moving Coil cartridge. ? Phono Input for record player with Moving Coil (low output and low impedance) car- tridge. ? If your record player has a separate Ground wire, attach it here to avoid hum noise. ? Connect the trigger Input (if available) on one or two subwoofers to these trigger ON/ OFF output jacks. When you switch ON the HK 990, it sends a trigger signal, which switches ON the subwoofer. When switching OFF the HK 990, the subwoofer also switches OFF. ? HRS (High-Resolution Synchronization) Input. Use the included HRS-cable to connect the HD 990 CD player (or other similarly equipped player) for optimum sound quality. ? Optical Digital Inputs (TOS-Link). Connect any digital device with Optical Digital Output to one of these Inputs. Push the Optical Jack through the hinged door that covers the Input until it clicks into place. ? Coaxial Digital Inputs. Connect any digital device with Coaxial Digital Output to one of these Inputs. Usually, Coaxial Digital transmis- sion is preferred to Optical, given a choice. ? Remote IN. To control your HK 990 with an external infrared remote sensor, connect the wire from the remote sensor here. ? Remote OUT. Connect other Harman Kardon devices (you may also experiment with other brands) that you wish to control with the HK 990 Remote Control to this Output. 3 REMOTE CONTROL Remote Control Band: Switches between frequency bands on a Tuner.
