The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to
alert the user to the presence
of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock
to persons.
The exclamation point within an
equilateral triangle is intended to
alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature

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
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-channel 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
®
name, more than capable of
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

in amber when the unit is in the Standby mode
to signal that the unit is ready to be turned on.
When the unit is in operation, the indicator will
turn white.
1 System Power Control: Press this button
to turn on the HK 990; press it again to turn the
unit off (to Standby). Entering Standby also saves
all Setup parameters.
2 Speaker 1/2 Selectors: Press to select
speaker pair 1 or 2, or both, or neither (headphone output only).
3 Record Out Selector: First press shows the
record source presently selected in the display.
Pressing on the the Source selectors 4 within
a few seconds after pressing 3 changes the
record source. Exit this function by pressing 3
again, or wait for a few seconds until exit takes
place automatically.
4 Input Source Selector: Select input source
for listening by pressing one of the ”Source” buttons repeatedly to scroll through all the Inputs
either forwards or backwards, until the display
shows the desired source.
5 Input Setup Button: Press this Button to
enter/exit the Input Setup Mode. Here you can
select the physical connection for each source
(Analog/Digital etc.) as well as Gain, Bass/Treble
etc. Refer to the Setup section of this manual.

update. 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 record-
ing. 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 AUX input jacks, suitable for analog signals
from video games, video recorders etc.

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 Loudspeaker output, System 2.
F Left Loudspeaker output, System 1.
G Power lead AC input.
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 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 switching
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 (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.
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.
