Introduction
Congratulations on your choice of the Harman Kardon HK 990 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:
In terms of raw power, the HK 990 is the most muscular amplifier ever to carry the harman/kardon® name, more than capable of driving the most demanding loudspeaker loads without breaking a sweat. But the HK 990’s awesome power is nothing if not highly refined, extending beyond watts and amps. With a choice of discrete optical or coaxial inputs or an analogonly signal path, as well as fourth-generation Real-Time Linear Smoothing (RLS IV), 2.2-chan- nel EzSet/EQ room optimization, dual subwoofer outputs and an audiophile-quality phono preamp section, the HK 990 offers a combination of features you will find irresistible. Others, of course, may simply hunger for all that power. We understand completely.
•High Current Capability provides the instantaneous current necessary to precisely drive and control nearly any loudspeaker system
•Ultrawide-bandwidth amplifier design for improved transient accuracy and phase linearity
•Low negative feedback for further improved dynamic accuracy
•Use of discrete electronic circuitry to provide the highest performance level
•Dual-path technology allows for pure analog or pure digital audio processing within the same product
•EzSet/EQ room optimization for quick and accurate system setup, optimized for two channels and two subwoofers
•Symmetric (balanced) XLR analog inputs offer lower noise levels and higher Signal-to-Noise performance
•RLS IV digital-to-analog conversion technology, with dual conversion using two stereo AD1955 high-grade DACs in Dual Mono configuration
•The HRS link allows Harman Kardon CD players to lock themselves to the external clock of the amplifier for a jitter-free connection, similar to having the CD playback inside the amplifier
•Dual differential input stages with their own high-voltage supply, resulting in high gain and low noise as well as high channel separation
•Cascoded predriver stage considerably reduces high-frequency distortion, allowing crystalclear high frequencies, free from any harsh sound
•Thermal Tracking Mechanism using ThermalTrak™ output stage transistors that include internal temperature sensors to bias the current of the output stage in real time
•Sophisticated electronic protection circuitry guards the amplifier from short-circuit or from damaged speakers and wires, without impairing sound quality, by using current limiting or output relays
•DC servo to ensure that the DC level of the amplifier output will stay within a contained limit at any condition
•Multiple protection circuits will switch the amplifier off in case overcurrent, overvoltage, overtemperature or DC protection is detected
•Dual toroidal transformers and up to 15.000μF of supply filtering per channel for high channel separation and tight bass control, even with low-impedance loads
•Dual-line dot-matrix display
•Record out available in both digital and analog domains (two analog outputs and one coaxial digital output)
•A/B speaker switching
•IR remote extension jacks for control of the amplifier when placed in a cabinet
•Harman Kardon system remote for control of compatible Harman Kardon CD players and tuners

•Remote Control + 4 AAA batteries

DBalanced 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 J). Pin configuration for the XLR Inputs: Pin 1 is Ground, Pin 2 is Plus/Hot, Pin 3 is Minus/Cold.
E Left Loudspeaker output, System 2.
F Left Loudspeaker output, System 1.
G Power lead AC input.
HTUNER analog Input jacks.
IPROCESSOR Analog 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!
JCD analog Input jacks. You can select either this Input or the Balanced Input as analog Input in the CD Input Setup Mode.
KPhono Input for record player with Moving Magnet (high output and high impedance) or High-Output Moving Coil cartridge.
LPhono Input for record player with Moving Coil (low output and low impedance) cartridge.
MIf your record player has a separate Ground wire, attach it here to avoid hum noise.
NConnect 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.
OHRS (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.
POptical 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.
QCoaxial Digital Inputs. Connect any digital device with Coaxial Digital Output to one of these Inputs. Usually, Coaxial Digital transmission is preferred to Optical, given a choice.
RRemote IN. To control your HK 990 with an external infrared remote sensor, connect the wire from the remote sensor here.
SRemote 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.
