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^™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.

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

thermaltracking mechanism usingthermaltrak^™output stage transistors that include

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

Connections

Connecting Other Components

1. make sure your ampliﬁer and other components are turned off.

2. connect each component’s output/play jacks to the corresponding input jacks on the

back of your ampliﬁer and, if available, the component’s input/record jacks to the

output jacks of the hK 990. use the white, black or gray plugs to connect left-channel

jacks; use the red plugs for right-channel jacks.

Wired Remote Control

to control your ampliﬁer with an external infrared remote sensor,connect the wire from the

remote sensor to the remote In jack on the back panel.or,if another stereo component has

a built-in infrared remote sensor and a remote out jack, it may be possible to connect this

jack to the remote In jack of your ampliﬁer. all harman Kardon products with remote In

and remote out jacks are compatible with one another, except for the citation 22, 24

and 25.

other manufacturers’ remote sensors and components may not be compatible, but it will

not hurt to experiment. a second wire may be used to connect your ampliﬁer’s remote

out jack to the remote input of another stereo component. continue this process to

include additional components (if compatible).

Connecting Speakers

3. for best performance, use high-quality speaker cables. however, ordinary copper wire

can be used if the gauge meets the following requirements:

Wire length

min. diameter

1/32" (1mm)

3/64" (1.25mm)

1/16" (1.6mm)

5/64–3/32" (2–2.5mm)

up to 8.2 feet (up to 2.5 meters)

up to 13.1 feet (up to 4 meters)

up to 19.7 feet (up to 6 meters)

above 19.7 feet (above 6 meters)

4. avoid rolling excess wire with or near signal interconnects.

IMPORTANT: When connecting two pairs of speakers, determine the impedance of each

pair by looking on the back of the speakers or in your owner’s manual, or by contacting

your dealer or manufacturer.

You can listen to two pairs of speakers at the same time ONLY if the impedance of

EACH speaker is NOT LESS THAN 8 ohms.

WARNING: do not play sets of speakers simultaneously except as recommended above.

ampliﬁer may overheat.

HK 990

Setup Instructions

Audio Mode

Speaker Setup

the hK 990 can handle analog as well as digital signals. It can process any input in the

digital domain to equalize the signal and tailor the sound to the loudspeakers and room

acoustics, once either the ezset/eQ or the manual bass management has been set up

(see below).

When pressing the speaker setup button, a menu opens to offer a choice between

manual mode or ezset/eQ setup. below is a description of both options.

Manual Mode

you choose the method and the processing according to your preference within the Input

setup menu.

If you know your system and your room well and simply want to manage the low-

frequency response of your system without correcting the frequency response of

subwoofers and main speakers, select the manual mode. this is a basic bass manager

setup.

the ﬁve audio modes are as follows:

1. Direct Path: selection of the direct path is an analog-input-only option. It bypasses

all digital processing (adc, dsp and dac) to reduce the signal path to an absolute

minimum, consisting of volume control only. If you select an input to be associated

with a digital source, the direct path setting is not available, being an analog-only

option.

once manual mode has been selected, follow the steps below:

1. “Subwoofer 1 On/Off”: select “on” if a subwoofer is connected to the sub 1

output.

2. “Subwoofer 2 On/Off”: select “on” if a subwoofer is connected to the sub 2

output.

2. DSP Path: selecting the dsp path opens access to the tone-control circuits. In this

mode, the analog signals are routed to the a/d converter, digital sound processor and

d/a converter path prior to volume adjustment.

3. “Crossover Frequency”: If either sub1 or sub2 is on, you can select the crossover

frequency, where the main speakers’ lower frequency limit and the subwoofer’s

upper frequency limit is placed. the setting goes from 40 to 200hz in 10hz steps.

3. EQ1 LF (low-frequency correction): this mode should be selected once the

ezset/eQ setup has been carried out (see below). If selected before the ezset/eQ

setup, it will simply provide the same result as the dsp path, being a ﬂat response

with access to the tone controls. the eQ1 lf mode is the ﬁrst preset available after

the ezset/eQ calibration has been carried out. this preset processes the subwoofer

channels only, correcting the acoustics of the room in the low-frequency range while

keeping the response curve of the main speakers unchanged.

4. Save and Exit: to save the steps 1 to 3, press enter after each step.

EzSet/EQ Mode

If you want to beneﬁt from the hK 990’s advanced, automatic frequency correction and

setup system, select ezset/eQ mode. the process is described in detail below.

4. EQ2 LF+MF (low- and mid-frequency correction): this mode should be selected

once the ezset/eQ setup has been carried out (see below). If selected before the

ezset/eQ setup, it will simply provide the same result as the dsp path, being a ﬂat

response with access to tone controls. the eQ2 lf + mf mode is the second preset

available after the ezset/eQ calibration has been carried out. this preset is active for

the low- and mid-frequency responses of both the main speakers and the subwoofers

when it calibrates the system to the room. as a result, both the subwoofer and main

speaker response curves are modiﬁed to accommodate the system response to the

room. the response curve of the main speakers is corrected up to 1khz and kept

unaffected above this frequency, leaving the rest of the audio spectrum unaffected.

Setup Process

the setup process consists of the following steps:

1. “Subwoofer 1 On/Off”: select “on” if a subwoofer is connected to the sub 1

output.

2. “Subwoofer 2 On/Off”: select “on” if a subwoofer is connected to the sub 2

output.

3. “Crossover Frequency Automatic/Manual” (only if at least one subwoofer is

connected to the HK 990): select whether you want to set a crossover frequency

of your choice manually or let the hK 990’s algorithm measure your main speaker

limitations automatically.

5. EQ3 LF + MF + HF (low-, mid- and high-frequency correction): this mode should

be selected once the ezset/eQ setup has been carried out (see below). If selected

before the ezset/eQ setup, it will simply provide the same result as the dsp path,

being a ﬂat response with access to tone controls.the eQ3 lf + mf + hf mode is the

third preset available after the ezset/eQ calibration has been carried out. this preset

optimizes not only the main speaker and subwoofer responses to accommodate the

room acoustics, but also corrects the high-frequency response of the speaker at the

listening position by correcting off-axis response.

•

Manual Mode:

“crossover frequency”: select which crossover frequency you want for the

system, between 40 and 200hz in 10hz steps. When the frequency is adjusted,

you will be asked to follow the same steps as below in the automatic mode.

•

Automatic Mode:

please observe that all the ﬁve audio modes described above can be selected

independently for all inputs.

a) “connect mic and place it at listening position”: following this message,

connect the supplied measuring microphone to the front-panel jack shared

with headphones. place it in your listening position, at the correct height, then

press enter. In order to read the complete message on the display, press the >

arrow button on the remote.

Gain

the level of different sources may vary. to avoid annoying level changes when switching

between inputs, gain adjustment from –6db to +6db is an option for each Input. the

processor input has a different range (–24db to +6db), to accommodate the output

levels of most processors.

b) the systemgenerates two loud, brief frequency sweeps through the speakers.

Ifyou are notcomfortable with loud noise, use ear plugs orhavesomeone else

performthecalibration. the volume of the sweeps is pre-determined. you can

control this level by simply adjusting the volume with the Volume button on the

front panel or with the Volume buttons on the remote control. please note that

if you set the volume too low, the calibration does not function, and setting it

too loud may damage your loudspeakers. after calibration is performed, the

volume reverts to the level that you used previously.

Bass and Treble

bass and treble adjustment is accessible only when the audio mode is not direct (i.e., is

set to dsp, eQ 1, eQ 2 or eQ 3). When in this mode, you can adjust the bass and treble

from –10 to +10db below 100hz and above 10khz.

When the sweeps have been done, you may get an error message “mic or

speaker not detected” in the display. In this case, check the connection to

the microphone and/or increase the volume slightly; then press enter again.

If no error is found, the system will bring you to step 3. If you still get an error

message, you must switch off the ampliﬁer to exit the calibration menu.

Setup Instructions

c) once the sweeps are performed without error, the display will show “filter

design, please wait…” during this process, the ﬁlter parameters are computed

and written into the dsp ﬂash memory. When this is done, the system goes to

step 4.

Near Field

the next sweeps measured in front of each speaker (steps 4 and 5) serve to correct the

on-axis response of the main speakers. by applying sweeps to each speaker, a correction

curve above 1khz is generated for each speaker. the curves are stored after step 7.

d) “place mic at 60cm in front of the left speaker” appears in the display. position

the microphone as prompted (60cm is about two feet), preferably at normal

listening height (you may use a photo tripod; there is a threaded hole at the

bottom of the microphone for this purpose). then press enter. a new sweep will

be generated. If it is unsuccessful, you will be asked to check the distance or

the volume of the system with this message in the display: “Wrong distance or

level, please check and press enter.” If successful, you will go to step 5.

BassQ

If at least one subwoofer is connected, the ﬁnal steps of the ezset/eQ process adjust

the low-frequency response of the system, taking into consideration the acoustics of the

room. the system can correct up to two subwoofers in its processing loop. using two

subwoofers offers the advantage of a more linear low-frequency characteristic, limiting

the node effects usually found in this frequency range.

the curves are stored after step 7.

e) “place mic at 60cm in front of the right speaker” appears in the display. again,

position the microphone as prompted (60cm or two feet), then press enter. a

new sweep will be generated. If it is unsuccessful, you will be asked to check

the distance or the volume of the system with this message in the display:

“Wrong distance or level, please check and press enter.” If successful, you will

go to step 6 if at least one subwoofer is connected, or to step 7 in a pure 2.0

system.

EQ Preset

the hK 990 provides direct access to the three sets of ﬁlters via the remote control

through the eQ preset button. use this button to toggle between these three modes:

1. bassQ (eQ1 lf)

2. bassQ + far field (eQ2 lf + mf)

3. bassQ + far field + near field (eQ3 lf + mf + hf)

f) there are two possibilities at this stage,depending on the number of subwoofers

selected in step 1 of the setup process:

It will also toggle through the direct and dsp paths, thus allowing ﬁve possible settings.

note that the eQ preset button is in fact a shortcut button for the audio mode function of

the Input setup described above.

•

One Subwoofer: the display shows this message: “place mic at listening

position, press enter.” after you do it, two sweeps are generated. If

successful, you will jump to step 7. If not, the following message is shown:

“sub not connected or incorrect level, please check and press enter.” check

the connection and/or adjust the subwoofer level and press enter again.

When successful, you will go to step 7.

the ezset/eQ measurements are stored in a ﬂash memory and are not lost even if the

ampliﬁer is disconnected from the ac mains.

•

Two Subwoofers: the display shows this message: “place mic at 1st

listening position, press enter.” place the microphone 90cm (about three

feet) to the left of your listening position. after pressing enter, four sweeps

are generated.then you will be asked to “place mic at 2nd listening position,

press enter.” now place the microphone 90cm to the right of your listening

position. after pressing enter, two sweeps are generated. If successful you

will jump to step 7. If not, the following message is shown: “sub 1 or 2

not connected or incorrect level, please check and press enter.” check the

connections and/or adjust the subwoofer levels and press enter again. When

successful, you will go to step 7.

Level Settings

the level settings menu permits adjusting the levels of the different activated speakers

and subwoofer(s) of the system. depending on what was adjusted during the speaker

setup process, sub1 and/or sub2 may or may not be activated.

the level settings menu adjustments are:

1. to adjust the balance between left and right speakers up to 12db for each side.

2. to adjust the subwoofer 1 level between + and – 6db (when on).

3. to adjust the subwoofer 2 level between + and – 6db (when on).

g) the setup procedure is now complete, and the display shows this message:

“eQ setup completed, unplug microphone, press enter to save eQ setup.” press

enter as prompted. the display shows: “saving system equalization.”

now the hK 990 goes back to the previous playback mode, and you can test the results

of the setup process by going through the various options, pressing the eQ preset button

repeatedly (see below).

EzSet/EQ Description

during the automatic ezset/eQ process, several frequency sweeps were made. here is a

brief explanation of their use.

Far Field

the ﬁrst sweeps that occur during step 2 are used to calibrate the speaker system (adjust

relative levels and delay, and determine the crossover frequency if “manual crossover

frequency” was not selected earlier).also, the low-frequency response of the speakers is

equalized by applying a correction curve (with a range of 20hz to 1khz). this is the curve

that is stored during the “filter design” phase.

Operating Instructions

Listening to Your CD Player, Tape Deck, Tuner or

Other Source

1. press the power switch 2 to turn on the ampliﬁer. the power indicator lights white

and the protection circuitry checks for short circuits or other problems for a few

seconds before sound output.

2. press “speaker 1” to hear loudspeakers connected to the rear speaker 1 terminals.

press “speaker 2” to hear loudspeakers connected to the rear speaker 2 terminals.

press both to hear both speaker pairs at once. to listen to headphones only, press to

turn off any active speaker pair.

3. select desired source for listening by pressing the front-panel source selector (5)

up or down button repeatedly until the name of the source is shown in the main

Information display, or by pressing the desired system on button on the remote control.

please take the time to associate physical input jacks to source names; then press the

power button to place the ampliﬁer in standby to have it save your preferences.

4. begin playing the desired source.

5. adjust the volume control to the desired level.

With the Input setup, you may adjust bass and treble as well as balance if you have not

already done this during the setup process.

With the eQ preset you can select one, two or three stages of equalization, if you did

already perform the ezset/eQ setup automated adjusting process as described above.

Making a Recording

you may record any source to tape or to cdr or to both simultaneously. you may also

connect a second tape deck to the cdr inputs and outputs to record from tape to tape (in

either direction).

to select the desired source for recording (it can be a source different from the one being

listened to), press the record out button, followed by the source selector up or down

button on the front panel, repeatedly until the indicator for the name of the source to be

recorded is shown in the main Information display. all input signals, digital or analog, are

available for recording in both digital and analog form.this means that if you wish to copy

a vinyl record to a digital recorder, you simply start vinyl play, select “phono” as record

source and begin recording on your digital recorder. the built-in analog/digital converters

transform the analog phono signal to digital form.the reverse is also possible: if you have

connected a cd player to the hK 990 with a digital cable, its signal is available from the

analog recording outputs as well as the digital outputs.

NOTE: the record-output signal is taken directly from the program source and is

unaffected by the volume, bass, treble or balance controls.

Important Notes:

•

“record source” can be selected on the front panel only, not from the remote

control.

three-head cassette decks with monitoring function can be connected to tape or cdr

connectors, too, but their monitoring function cannot be used.

always turn the hK 990 to standby with the power button before unplugging the

power cord (or before switching off an external multiplug). this saves your current

setup in the memory, in addition to safely switching off the power-ampliﬁer section

of the hK 990.
