OPERATION 33

When the 6-Channel/8-Channel direct inputs are
in use there is no surround processing, as these
inputs take the analog output signals from an
optional, external DVD-Audio or SACD player, or
another source device and carry them straight
through to the volume control.

To listen to a program in traditional two-channel
stereo, using the front left and front right 
speakers only (plus the subwoofer, if installed and
configured), press the Stereo Button 5

until 

SURR OFF

appears in the Main

Information Display ˜.

Digital audio is a major advancement over older
analog surround processing systems such as
Dolby Pro Logic. It delivers five or six discrete
channels: left front, center, right front, left
surround and right surround and with DTS ES
(see below) even surround back (with identical
signals for left and right). Each channel repro-
duces full frequency range (20Hz to 20kHz) and
offers dramatically improved dynamic range and
significant improvements to signal-to-noise
ratios. In addition, digital systems have the
capability to deliver an additional channel that is
specifically devoted to low-frequency infor-
mation. This is the “.1” channel referred to when
you see these systems described as “5.1,” “6.1”
or “7.1”. The bass channel is separate from the
other channels, but since it is intentionally
bandwidth-limited, sound designers have given it
that unique designation.

Dolby Digital 
Dolby Digital (originally known as AC-3

®

) is 

a standard part of DVD, and is available on 
specially encoded LD discs and satellite
broadcasts and it is a part of the new high-
definition television (HDTV) system.

Note that an optional, external RF demodulator
is required to use the AVR 5550 to listen to the
Dolby Digital sound tracks available on laser
discs. Connect the RF output of the LD player to
the demodulator and then connect the digital
output of the demodulator to the Optical or
Coaxial inputs 

!$*Ó of the AVR 5550.

No demodulator is required for use with DVD
players or DTS-encoded laser discs.

DTS
DTS is another digital audio system that is capa-
ble of delivering 5.1, 6.1 or 7.1 audio. Although
both DTS and Dolby Digital are digital, they use
different methods of encoding the signals, and
thus they require different decoding circuits to
convert the digital signals back to analog.

DTS-encoded sound tracks are available on select
DVD and LD discs, as well as on special audio-
only DTS CDs. You may use any LD, DVD or CD
player equipped with a digital output to play
DTS-encoded special audio-only CDs with the
AVR 5550, but DTS-LDs can be played on LD
players and DTS-DVDs on DVD players only. All
that is required is to connect the player’s digital
output to either the Optical or Coaxial input on
the rear panel 

!$ or front panel *Ó.

In order to listen to DVDs encoded with DTS
sound tracks, the DVD player must be compatible
with the DTS signal as indicated by a DTS logo
on the player’s front panel. Note that early DVD
players may not be able to play DTS- encoded
DVDs. This does not indicate a problem with the
AVR 5550, as some players cannot pass the DTS
signal through to the digital outputs. If you are in
doubt as to the capability of your DVD player to
handle DTS DVDs, consult the player’s owner’s
manual.

Please note that some DVD players are shipped
with their output set for Dolby Digital only. To
insure that DTS data is being sent to the AVR,
please check the setup menu system on your
DVD player to make certain that DTS data output
is enabled.

PCM Audio Playback
PCM (Pulse Code Modulation) is the non- com-
pressed digital audio system used for compact
discs, Non-Dolby Digital/DTS Laserdiscs and some
special PCM encoded DVDs. The digital circuits in
the AVR 5550 are capable of high quality digital-
to-analog decoding, and they may be connected
directly to the digital audio output of your
CD/DVD or LD player (LD only for PCM or DTS
programs, for Dolby Digital laser discs an RF
adapter is needed, see ”Dolby Digital” above).

Connections may be made to either the Optical
or Coaxial inputs 

!$ on the rear panel or the

front panel Digital Inputs *Ó.

To listen to a PCM digital source, first select the
input for the desired source (e.g., CD) to feed its
video signal (if any) to the TV monitor and to
provide its analog audio signal for recording.
Next press the Digital Select button Û

G

and then use the 

⁄

¤

buttons 

D on the

remote, or the Selector buttons 7$ on the
front panel, until the desired choice appears in the

Lower Display Line B, then press the Set but-
ton @

F to confirm the choice.

During PCM playback the unit automatically will
turn to the default surround mode or to the

LOGIC 7

mode but you also may select any

surround mode except Dolby Digital or DTS.
When an HDCD encoded disc is being played
(see below) and the CD player is connected to
the AVR 5550 via a digital connection, select
Surround Off as the Surround mode to enjoy the
benefits of the HDCD process.

HDCD
HDCD, which stands for High Definition Com-
patible Digital

®

, is a sophisticated process that

enables the AVR 5550 to deliver outstanding 
digital-to-analog decoding of PCM signals from
any DVD or CD player, connected to a digital
input on the AVR 5550 even when normal,
non-HDCD-compatible players are used (only a
digital output is needed).

When a CD with the HDCD recording is played,
the AVR 5550 is able to take advantage of the
special recording process that is used in the 
creation of HDCD disc. The special circuitry
enables audio with extraordinary fidelity,
stunning resolution and the highest possible
overall quality.

As long as a digital input and the pure Stereo
mode (Surround Off) are selected, the AVR 5550
will automatically sense that it is an HDCD
recording.

It is important to note that the HDCD process is
completely compatible with standard recordings.
Indeed, the high-quality digital-to-analog 
circuitry that is part of HDCD and the HDCD
decoder chip, replacing the monolithic digital 
filters used in conventional DACs, will enable
enhanced performance also with normal,
non-HDCD encoded program material.

MP3 Audio Playback
The AVR 5550 is one of the few A/V receivers to
provide on-board decoding for the MP3 audio
format used on specific computer audio files and
by portable MP3 players/recorders. In addition,
some new CD and DVD players are capable of
playing back optical discs that are recorded with
MP3, rather than standard CD audio information.
By offering MP3 decoding, the AVR 5550 is able
to deliver more precise conversion of the digital
signals to an analog output, along with the 
benefits of listening to MP3 audio through the
AVR 5550’s high current amplifier and the 
speakers from your surround system, rather than
the smaller speakers and low powered amplifiers
typically used with computers.

34 OPERATION

To take advantage of the AVR 5550’s MP3 capa-
bilities, simply connect the digital (SPDIF) output
of a computer sound card able to feed the MP3
format to its digital output, or the digital (SPDIF)
output of MP3 compatible CD or DVD players or
of a portable MP3 player with a digital output to
either the rear panel Digital Inputs

!$ or

the front panel Digital Inputs *Ó.

NOTES:
• The AVR 5550 is only capable of playing signals
in the MP3 (MPEG 1/Layer 3) format. It is not
compatible with other computer audio codecs.

• The MP 3 DSP mode found in the new 
AVR 5550 requires an MP3 SPDIF stream.
Presently, only a few units provide this but in the
coming generations of motherboards and 
operating system updates this will follow, since
SPDIF is the standard for audio & video 
hardware.

• The digital audio input signal may be either
optical or coaxial, but the signal must be in the
MP3 SPDIF format. Direct connection of USB or
serial data outputs is not possible, even though
the signals are in the MP3 format. If you have
any questions about the data output format from
your computer or a sound card, check with the
device’s Owner’s Manual or contact the 
manufacturer’s technical support area.

• If your computer or sound card’s digital output
is not capable of direct connection to the AVR or
if the output is not capable of delivering MP3
data stream, you may use an optional, external
transcoder, such as those available from Harman
Kardon to convert the USB output of a computer
to a format compatible with the AVR. Contact
your Harman Kardon dealer for additional details.

Selecting a Digital Source
To utilize either digital mode you must have 
properly connected a digital source to the 
AVR 5550. Connect the digital outputs from DVD
players, HDTV receivers, satellite systems or CD
players to the Optical or Coaxial inputs on the
rear or front panel 

!$*Ó. In order to 

provide a backup signal and a source for analog
stereo recording, the analog outputs provided on
digital source equipment should also be 
connected to their appropriate inputs on the 
AVR 5550 rear panel (e.g., connect the analog
stereo audio output from a DVD to the DVD
Audio inputs

  on the rear panel when you

connect the source’s digital outputs).

To select a digital source such as DVD, first select
its input using the remote or front panel Input
Selector

4% as outlined in this manual in

order to feed its video signal (if any) to the TV
monitor and to provide its analog audio signal for
recording. When the digital input associated with
the input selected (e.g. “DVD”) is not selected
automatically (due to the input settings made

earlier during the system configuration, see page
21), select the digital source by pressing the
Digital Input Selector button 

G Û and

then using the 

⁄

/

¤

buttons 

D on the remote

or the Selector buttons 7$ on the front panel
to choose any of the 

OPTICAL

or 

COAXIAL

inputs, as they appear in the

Upper Display Line A or on-screen display.

When the digital source is playing, the AVR 5550
will automatically detect whether it is a multi-
channel Dolby Digital or DTS source or a HDCD,
MP3 or conventional PCM signal, which is the
standard output from CD players.

Note that a digital input (e.g. coaxial) remains
associated with any analog input (e.g. DVD) as
soon as it is selected, thus the digital input need
not be re-selected each time the appropriate
input choice (e.g. DVD) is made.

Digital Bitstream Indicators
When a digital source is playing, the AVR 5550
senses the type of bitstream data that is present.
Using this information, the correct surround mode
will automatically be selected. For example, DTS
bitstreams will cause the unit to switch to DTS
decoding, and Dolby Digital bitstreams will enable
Dolby Digital decoding. When the unit senses
PCM data, from CDs and LDs and some music
DVDs or certain tracks on normal DVDs, it will
allow the appropriate surround mode to be select-
ed manually. Since the range of available surround
modes depends on the type of digital data that is
present, the AVR 5550 uses a variety of indicators
to let you know what type of signal is present.
This will help you to understand the choice of
modes and the input channels recorded on the
disc.

To help you see which type of digital source is
playing, the Surround Mode Indicators ˘ in
combination with the Information Display ˜
also serve as bitstream indications to show which
type of bitstream is present, as well as the sur-
round mode in use, if applicable.

DOLBY D

: When the green LED next to the

Dolby Digital or Dolby Digital EX mode is lit, a
Dolby Digital bitstream is being received.
Depending on the audio track selected on the
source player and number of channels on the
disc, different surround modes are possible. Note
that only one channel without subwoofer, called
”1.0” audio, or all five channels with subwoofer
(”5.1” audio) or all steps between can be record-
ed on digitally surround encoded audio tracks
(see NOTE below). With all those tracks, except
”2.0” audio, only the Dolby Digital and VMAx
modes are available. When the Dolby Digital sig-
nal is only two channel (”2.0”) these two chan-
nels (l and r) often contain Pro Logic surround
informations.

With those tracks the AVR 5550 automatically
switches to the Dolby Pro Logic II Movie mode (in
addition to the Dolby Digital mode), but you may
also select the Vmax mode. When the D.D. 2.0
signal contains no Pro Logic information, the
pure Dolby Digital mode will be selected auto-
matically, but you may also select any Pro Logic II
mode (only Music or Emulation should be used
then) or any Vmax mode.

D T S

: When the green LED next to the DTS logo

is lit, a DTS bitstream is being received. When the
unit senses this type of data, only the applicable
mode may be used.

P C M

: When the green LED next to the word

DIGITAL is lit, a standard Pulse Code Modulation,
or PCM, signal is being received. This is the type of
digital audio used by conventional compact disc
and laser disc recordings. When a PCM bitstream
is present, all modes except Dolby Digital and DTS
are available.

®

: When the letters 

HDCD

appear on

the Lower Display Line B in conjunction with
the PCM indicator, the CD that is playing is
encoded using the special High Definition
Compatible Digital

®

process. HDCD

®

discs use

20-bit encoding and other proprietary processing
to provide the ultimate in CD listening. Note that
HDCD processing is only available in the Stereo
(Surround Off) mode.

M P 3

: When 

MP3

appears on the Lower

Display Line B, a compatible MPEG 1/Layer 3
digital signal is being received. This is the popular
audio format used by many computer programs
for recording compressed audio files. When an
MP3 bitstream is present, the sound will 
automatically be played in the stereo (Surround
Off) mode. The surround modes are not available
during MP3 playback.

Speaker/Channel Indicators
In addition to the Bitstream Indicators, the 
AVR 5550 features a set of unique channel-input
indicators that tell you how many channels of
digital information are being received and/or
whether the digital signal is interrupted.
(See Figure 9).

OPERATION  35

These indicators are the L/C/R/LFE/SL/SR/SBL/SBR
letters that are inside the center boxes of the
Speaker/Channel Input Indicators E in the
front panel Main Information Display ˜.
When a standard analog stereo or matrix 
surround signal is in use, only the “L” and “R”
indicators will light, as analog signals have only
left and right channels.

Digital signals, however, may have one, two, five,
six or seven separate channels, depending on the
program material, the method of transmission
and the way in which it was encoded. When a
digital signal is playing, the letters in these 
indicators will light in response to the specific
signal being received. It is important to note that
although Dolby Digital, for example, is referred to
as a “5.1” system, not all Dolby Digital DVDs or
audio tracks selected on DVD or other Dolby
Digital programs are encoded for 5.1. Thus, it is
sometimes normal for a DVD with a Dolby Digital
soundtrack to trigger only the “L” and “R”
indicators.

NOTE: Many DVD discs are recorded with both
“5.1” and “2.0” versions of the same sound-
track. When playing a DVD, always be certain to
check the type of material on the disc. Most discs
show this information in the form of a listing or
icon on the back of the disc jacket. When a disc
does offer multiple soundtrack choices, you may
have to make some adjustments to your DVD
player (usually with the “Audio Select” button or
in a menu screen on the disc) to send a full 5.1
feed to the AVR 5550 or to select the appropriate
audio track and thus language. It is also possible
for the type of signal feed to change during the
course of a DVD playback. In some cases the pre-
views of special material will only be recorded in
2.0 audio, while the main feature is available in
5.1 audio. As long as your DVD player is set for
6-channel output, the AVR 5550 will automati-
cally sense changes to the bitstream and channel
count and reflect them in these indicators.

Important Note: When a digital surround
source (Dolby Digital, DTS) is played, the letters
SBL/SBR for the Surround Back channels will
appear only when a DTS ES DISCRETE 6.1 source
is played. Then this surround mode will be
indicated in the front display and on-screen
display. With all other recordings the icons for the
surround back speakers may light (when those
speakers have been configured) to indicate that a
signal will be fed to them (Matrix decoded with
NEO:6, LOGIC 7 or 7 CH Stereo), but no letters
inside will light as the unit will not receive an
input signal for the surround back channels.

The letters used by the Speaker/Channel Input
Indicators E also flash to indicate when a bit-
stream has been interrupted. This will happen
when a digital input source is selected before the
playback starts, or when a digital source such as
a DVD is put into a Pause mode. The flashing

indicators remind you that the playback has
stopped due to the absence of a digital signal
and not through any fault of the AVR 5550. This
is normal, and the digital playback will resume
once the playback is started again.

Night Mode 
A special feature of Dolby Digital is the Night
mode, which enables Dolby Digital input sources
to be played back with full digital intelligibilty
while reducing the maximum peak level and lift-
ing the low levels by 

1

/

4

to 

1

/

3

. This prevents

abruptly loud transitions from disturbing others
without reducing the impact of the digital source.
The Night mode is available only when the Dolby
Digital mode is selected.

The Night mode may be engaged when a Dolby
Digital DVD is playing by pressing the Night
Button 

B on the remote. Next, press the 

⁄

/

¤

buttons 

D to select either the middle range or

full compression versions of the Night mode. To
turn the Night mode off, press the 

⁄

/

¤

buttons

D until the message in the lower third of the
video display and the Lower Display Line B
reads 

D-RANGE OFF

.

The Night mode may also be selected to always
be on as soon as the Dolby Digital mode is 
activated at either level of compression using the
options in the 

Surround Select

menu. See page 25 for information on using the
menus to set this option.

IMPORTANT NOTES ON DIGITAL PLAYBACK:
• When the digital playback source is stopped, or
in a pause, fast forward or chapter search mode,
the digital audio data will momentarily stop, and
the channel position letters inside the Speaker/
Channel Indicators E will flash. This is normal
and does not indicate a problem with either the
AVR 5550 or the source machine. The AVR 5550
will return to digital playback as soon as the data
is available and when the machine is in a
standard play mode.

• Although the AVR 5550 will decode virtually all
DVD movies, CDs and HDTV sources, it is possible
that some future digital sources may not be com-
patible with the AVR 5550.

• Note that not all digitally encoded programs
and not all audio tracks on a DVD contain full
5.1 or 6.1 channel audio. Consult the program
guide that accompanies the DVD or laser disc to
determine which type of audio has been record-
ed on the disc. The AVR 5550 will automatically
sense the type of digital surround encoding used,
indicate it in the Channel Input Indicators E
and adjust to accommodate it.

• When a Dolby Digital or DTS source is playing,
you normally may not be able to select some of
the analog surround modes such as Dolby Pro
Logic II, Dolby 3 Stereo, Hall, Theater, 5CH/7CH
Stereo or Logic 7, except with specific Dolby

Digital 2.0 recordings that can be played with
the Pro Logic II modes too (see page 34).

• When a digital source is playing, it is possible
to make an analog recording using the Tape

#

or Video 1 or Video 2 or 

& record outputs,

even if the source is connected to any digital
input of the AVR 5550 only, as long as "Surround
Off" mode is selected (possible with a PCM
source only). But the analog two channel signal,
even of a Dolby Digital (not DTS) source, the
”Downmix” to Stereo or Dolby Surround, can be
recorded by connecting its analog audio outputs
to the appropriate analog inputs (e.g. DVD) of
the AVR 5550. Additionally, the digital signals
will be passed through to the Digital Audio
Outputs 

*.

In normal operation, the audio or video source
selected for listening through the AVR 5550 is
sent to the record outputs. This means that any
program you are watching or listening to may be
recorded simply by placing machines connected
to the outputs for Tape Outputs

# or Video 1

or 2 Outputs

& in the record mode.

When a digital audio recorder is connected to
any of the Digital Audio Outputs

*, you are

able to record the digital signal using a CD-R,
MiniDisc or other digital recording system.
Note that all digital signals will be passed
through to both, coaxial and optical, digital 
outputs simultanously, no matter which kind of
digital input was selected.

In addition to the rear panel digital outputs, the
AVR 5550 offers Harman Kardon’s exclusive con-
figurable front panel output jack feature. For easy
connection of portable devices, you may switch
the front panel Digital Coax 3 jack Ó or the
Video 4 jack Ô from an input to an output by
following these steps:

1. Press the OSD button 

L to view the 

M A S T E R M E N U

(Figure 1).

2. Press the Set button 

F to enter the

I N / O U T S E T U P

menu (Figure 2).

3. Press the 

¤

button 

D so that the on-screen

›

cursor is next to V I D E O 4 or 

C O A X I A L 3

depending on which input you

wish to change to an output. Either input, or
both may be changed at any time.

4. Press either of the 

‹

/

›

buttons 

E/& so

that the word O U T is highlighted.

5. Press the OSD button 

L to exit the menus

and return to normal operation.

Note that once the setting is made, the appropri-
ate Input/Output Status Indicator ( will
turn red, indicating that the selected analog or

36 OPERATION

digital jacks are now an output, instead of in the
default setting as an input. Once changed to an
output, the setting will remain as long as the
AVR 5550 is turned on, unless the setting is
changed in the OSD menu system, as described
above. Note, however, that once the AVR 5550 is
turned off, the setting is cancelled. When the unit
is turned on again, the front panel jacks will
return to their normal default setting as an input.
If you wish to use the jacks as an output at a
future time, the setting must be changed again
using the OSD menu system, as described above.

NOTES:
• The digital outputs are active only when a digital
signal is present, and they do not convert an ana-
log input to a digital signal, or change the format
of the digital signal (e.g. Dolby Digital to PCM or
vice versa, but coaxial digital signals are converted
to optical signals and vice versa). In additon, the
digital recorder must be compatible with the
output signal. For example, the PCM digital output
from a CD player may be recorded on a CD-R or
MiniDisc, but Dolby Digital or DTS signals may not.

• To make an analog recording from a digital
source is possible, but only from a PCM source
(not Dolby Digital or DTS) and correctly only with
"Surround Off" mode (with any Surround mode
only the L/R front signals will be fed to the record
outputs).

Normal output level adjustment for the 
AVR 5550 is established using the test tone, as
outlined on page 26. In some cases, however, it
may be desirable to adjust the output levels
using program material such as a test disc, or a
selection you are familiar with. Additionally, the
output level for the subwoofer and those for the
Stereo and VMAx modes can only be adjusted
using this procedure. Note that all adjustments
made with any input will be effective with all
inputs selected, just as it is the case with the
adjustment using the test tone.

To adjust the output levels using program materi-
al, first select the surround mode for which you
want to trim the speakers (see NOTE below), start
your program material source and set the 
reference volume for the front left and front right
channels using the Volume Control

)î.

Once the reference level has been set, press the
Channel Select button 

CÙ and note that

FRONT L LEVEL

will appear in the Lower

Display Line B. To change the level, first press
the Set button 

F @, and then use the

Selector buttons 7$ or the 

⁄

¤

buttons

D to raise or lower the level. DO NOT use the
volume control, as this will alter the reference
setting.

Once the change has been made, press the Set
button 

F @ and then press the Selector but-

tons 7$ or the 

⁄

/

¤

buttons 

D to select

the next output channel location that you wish to
adjust. To adjust the subwoofer level, press the
Selector buttons 7$ or the 

⁄

/

¤

buttons

D until 

WOOFER LEVEL

appears in the

Main Information Display ˜ or on-screen
display (only available if the subwoofer is turned
on).

Press the Set button 

F @ when the name of

the desired channel appears in the Main
Information Display ˜ and on-screen 
display, and follow the instructions shown above
to adjust the level.

Repeat the procedure as needed until all chan-
nels requiring adjustment have been set. When
all adjustments have been made and no further
adjustments are made for five seconds, the 
AVR 5550 will return to normal operation.

If you are using a disc with noise test signals or
an external signal generator as the source from
which to trim the output levels, you may use the
EzSet feature of the remote to guide you to the
correct SPL level. To use the remote for this pur-
pose, start the test tone from the source and
press and quickly release the SPL Indicator
Select

* to activate the sensor.

While the test tone is played, the Program/SPL
Indicator

2 will change color to indicate the

level. When it is red, the level is too high; when it
is orange, the level is too low. To set the refer-
ence level, open the Volume Control 

) until

the SPL Indicator´s LED lights green when the
test signal is fed to the left front speaker. Then
adjust the level of all other speakers, while they
are receiving the test signal, until the LED lights
green for all channels. After the output levels for
all channels are aligned, press the SPL
Indicator Select

* to turn the sensor and

indicator off.

The channel output may also be adjusted using
the full-OSD on-screen menu system. First, set
the volume to a comfortable listening level using
the Volume Control ı

to change the output level.
Remember, when you are using a disc with test
signal (e.g. pink noise) or an external signal
generator as the source, the goal is to have the
output level at each channel be equal when
heard at the listening position, with any surround
mode selected. When your test source is a nor-
mal disc with music signals, you may adjust the
level for each channel and surround mode as you
prefer, e.g. you may lower the center channel
level when you find it to be too high or increase
the level of the rears when you find it to be too
low with specific surround modes.

If you wish to reset all the levels to their original
factory default of 0dB offset, press the

ments. If you have no other adjustments to make,

system.

NOTE: The output levels may be separately
trimmed for each digital and analog surround
mode. If you wish to have different trim levels for a
specific mode, select that mode and then follow the
instructions in the steps shown above.

With Stereo and Vmax modes the adjustment
procedure described above is the only way to
trim the output level, e.g. to match the Stereo or
Vmax level with other modes.
