Introduction
Congratulations
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.
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 analog-only signal path, as well as fourth-generation Real-Time Linear
Smoothing (RLS IV), 2.2-channel EzSet / EQ
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.
The special features of this unit include:
High-current capability to provide the instantaneous current necessary to drive and •
control nearly any loudspeaker system precisely
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 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 for 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
HRS link for Harman Kardon CD players to lock themselves to the external clock of •
the amplifier for a jitter-free connection, similar to having 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 to reduce high-frequency distortion, allowing crystal-clear •
high frequencies, free from any harsh sound
Thermal Tracking Mechanism using ThermalTrak •
internal temperature sensors to bias the current of the output stage in real time
Sophisticated electronic-protection circuitry to guard 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 specified •
limit at any condition
Multiple protection circuits to 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
on your choice of the Harman Kardon® HK 990 Integrated Amplifier.

Connections
0 Right Speaker output, System 2.
1 Right Speaker output, System 1.
2 RS-232 connector for possible future PC update, plus Update switch.
3 Input jacks for one or two subwoofer signals from external surround processor.
4 Output jacks for two subwoofers.
5 Digital Coaxial output jack for digital recording. Also permits digital recording of
analog sources.
6 Preamplifier output jacks.
7 Analog output jacks for tape recording.
8 Analog output jacks for CD-recorder analog recording.
9 Auxiliary input jacks, suitable for analog signals from video games, video recorders,
etc.
A TV input jacks for analog-sound input from your TV.
B Tape input jacks for analog tape replay.
C CDR input jacks for CD-recorder analog replay.
D 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 J). Pin configuration for the XLR Inputs: Pin 1 is ground, Pin 2 is
plus/hot, Pin 3 is minus/cold.
E Left Speaker output, System 2.
F Left Speaker output, System 1.
G AC power-cord connection.
H Tuner analog-input jacks.
I Processor 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!
J CD analog-input jacks. You can select either this input or the balanced input (D) as
analog input in the CD Input Setup mode.
K Phono input for record player with Moving Magnet (high output and high impedance)
or High-Output Moving Coil cartridge.
L Phono input for record player with Moving Coil (low output and low impedance)
cartridge.
M If your record player has a separate ground wire, attach it here to avoid hum noise.
N 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 you switch off the HK 990, the subwoofer also
switches off.
O 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.
P Optical digital inputs (TOSLINK
output to one of these inputs. Push the Optical jack through the hinged door that
covers the input until it clicks into place.
Q Coaxial 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.
R Remote In. To control your HK 990 with an external infrared remote sensor, connect
the wire from the remote sensor here.
S 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.
