INSTALLATION  9

➞

To prevent possible damage to your speakers
and other components in your audio system, it is
important that ALL components, including the
HD 755 and your receiver or preamp and ampli-
fiers, are turned off and unplugged from their AC
power source when installing any new compo-
nent.

Connecting the HD 755 to your audio system is
simple. Using standard RCA-to-RCA interconnect
cords, connect the left and right Audio Output
jacks ™ on the rear panel to the CD input jacks
on your receiver, surround processor or preampli-
fier.

If your system includes an optional external 
digital-to-analog converter, or if you are using a
receiver or other processor that has the capabili-
ty to decode PCM digital input signals, connect
the Digital Output jack ¡ to the Coaxial
Digital input on the decoder. Make certain to use
a coaxial-style interconnect cable, as standard
audio cables will not perform as well.

Install two AA batteries by turning the remote
over so that you are holding the bottom side up.
Press lightly on the embossed arrow on the
cover and gently slide the cover towards you in
the direction of the arrow. Insert the batteries
inside the compartment, being careful to follow
the + and – polarity indications at the bottom of
the compartment. Replace the cover by placing it
on the remote and sliding it back towards the
top of the remote.

NOTE: When replacing batteries, always replace
both at the same time. When the unit will not be
used for an extended period of time, it is also a
good idea to remove the batteries so that the
potential for corrosion or damage is avoided.

If the HD 755 is installed behind a cabinet or
other obstruction that may block the path
between the front-panel Remote Sensor 3
and the location of the remote, an optional
external IR sensor may be used. Connect the
sensor to the Remote IR-In Jack £ on the
rear panel. This jack may also be connected to
the IR-Output jack of another compatible
Harman Kardon component or a compatible IR-
system- remote product.

You may also use the IR Sensor in the HD 755 to
send commands to other compatible remote
controlled products. Connect the Remote IR-
Out jack ¢ to the input of the other product
or system.

Connect the power to a nonswitched AC wall
outlet or to the accessory outlet on the rear of
another audio device in your system and you are
ready to go!

NOTE: When using the accessory outlet on
another product to power the HD 755 make cer-
tain that it has the compatibility to power a
device that draws at least 14 watts of current in
addition to being able to handle the require-
ments of the other devices that may be plugged
into the accessory outlets. If you use a
“switched” outlet, it is important to remember
that the host product must be turned on in order
for the HD 755 to operate.

Disc Handling Notes
When loading or unloading discs, it is best to
hold them by the edges.

While Compact Discs are very reliable, rough
handling may damage them. Avoid scratching the
bottom (non-printed) side of discs, or any
handling which will leave fingerprints.

To avoid damage to the disc and player, always
seat discs so that they are centered in the tray.

Do not lift the player while the disc tray is
opening or closing, as this may cause the disc to
unseat from the tray and possibly jam.

To play a disc, first turn the HD 755 on using the
Power Switch 1 on the front panel or the
Power On button 

1 on the remote control.

When the unit is turned off (to Standby), press-
ing any button on the front panel will turn the
unit on. When Play button 4

F.

Place a disc in the tray following the instructions
shown above.

Pressing the Open/Close button once a disc has
been carefully seated will close the disc drawer
while the message CLOSING will appear in the
information display. As soon as the tray is closed
the display will show the message TRACKING
while the table of content (TOC) of the disc is
read. Note that particulary with CD-RW discs
this tracking may take some time due to the
reflectibility and data structure different from
normal discs. Afterwards the Information Display
will show the total number of tracks on a disc
and the total running time of the disc.

The drawer will also close when the Play button
4

9 is pressed. The drawer will close and the

disc will start playing the first track.

To play all of the tracks on the disc in order, press

OPERATION  11

While the disc is playing, the track being played
will show as a number in the middle of the dis-
play just below the word TRACK. The elapsed
time of the track being played will also appear in
the display (see figure page 10). As a disc plays,
the track numbers will change, and the time will
reset to

at the start of each new track.

To momentarily pause the play of a disc, press
the Pause button 4

B. Note that a Pause

indication ± will appear in the display to remind
you that the disc is paused. Press either the

tracks and total running time of the disc.

To remove a disc from the player, press the
Open/Close button $. To prevent dirt and
dust from entering the unit, do not leave the
disc tray open.

To place the unit in a Standby mode, press the
Power Switch 1 on the front panel or the
Power Off button 

0 on the remote. The

display will show a STANDBY message for a
moment and the Status Mode Indicator 2
will glow orange, indicating that the unit is off,
but ready to accept a Power On command from
the remote. If the disc drawer is open, it will
automatically close when the unit is placed in
the Standby mode. This ensures that the unit will
not be harmed from dust, dirt or inadvertent
damage to the drawer mechanism.

Note that the unit is not removed from AC main
power when it is in the Standby mode but its
power consumption is reduced to a low value. To
remove the AC power completely from the unit
its Power Cord ∞ must be plugged into a
switch controlled AC outlet that is turned off. We
recommend to use the switched AC outlet on
the rear side of a receiver or amplifier. When that
AC outlet will be turned on, the HD 755 will
always turn to the Standby mode even if it was
on before the AC power was removed.

,

HDCD

®

, which stands for High Definition

Compatible Digital

®

, is a sophisticated process

that enables the HD 755 to deliver outstanding
digital-to-analog decoding no matter what type
of CD is played.

When a disc with the HDCD logo is played, the
HD 755 is able to take advantage of the special
recording process that is used in the creation of
HDCD discs. Although HDCD discs are playable
on any CD player, when they are played on a
unit such as the HD 755, the special circuitry
delivers audio with extraordinary fidelity, stun-
ning resolution and the highest possible overall
quality. The HDCD process effectively cancels the
additive distortions, caused by artifacts of the
A/D and D/A conversion processes, and simul-
tanously provides additional data to reduce the
subtractive distortions resulting from insufficient
data present in the 44.1 kHz, 16-bit PCM sam-
pling standard of the compact disc format.

No special adjustment is required to play an
HDCD disc. Simply play the disc as you would
any other CD, and the HD 755 will automatically
sense that it is an HDCD recording. The HDCD
Indicator ^ will illuminate on the front panel
to remind you that an HDCD disc is playing.

It is important to note that the HDCD process is
completely compatible with standard recordings.
Its high-quality digital filter and digital-to-analog
circuitry provides enhanced playback even from
all standard CD audio discs

You may listen to the output of the HD 755
through headphones by plugging a set of stan-
dard headphones with a 6,3 mm headphone
plug into the front panel Headphones Jack
#. The volume of the headphone output may
be adjusted with the Headphones Level knob
@. Note that changing the headphone level
will not change the volume for the main audio
output. This is a fixed output, and it is changed
using the volume control on your receiver,
preamplifier or surround processor.

In some situations, it may be desirable to reduce
the brightness of the display or to turn it off
completely. To do this, press the Display button
G on the remote once to dim the display to
half brightness. Press it again to turn the display
off. A third press will return the display to normal
level.

The HD 755’s time display is capable of showing
a wide range of information about a CD.

In normal operation the display will show the
total running time of a CD after the disc is first
put in the unit. When the disc is played, the
display will show the running time of a track in
play. Each time the track changes, the time
display will reset to 

and begin to

increase again as the new track plays.

To view the time remaining on an individual
track, press the Time button 

D on the remote

once. The display will now show the time left in
the track in play, and a ”-” will light in front of
the time display as a reminder of the display’s
status.

To view the total time remaining to play on the

disc, press the Time button again, a number
greater than the formerly shown track remaining
time (except the last track of the disc is played)
will appear in the display, again with a ”-” in
front.

When the Time button is pressed again the
display will return to show the running time of
the track in play.

Note: When a program is played (see page 13),
all time modes are selectable too except the
total time remaining on the disc.

12 OPERATION

If you wish to quickly scan through a disc to
locate a particular passage or program, press the
Search buttons 6

8. The Forward Search

button — plays the disc forward in high
speed, while the Reverse Search button ‚
plays the disc backwards in high speed. Holding
the buttons pressed will tripple the search speed
after 3 seconds. When the desired part of the
disc is heard, release the Search button to
resume normal play speed.

To move from one track on the disc to another
during play mode, press one of the Skip buttons
7

7. Pressing the Forward Skip button

fl· will move you forwards through the disc,
one track at a time, while pressing the Reverse
Skip button ‡fi once will move you back 
to the start of the actual track (as long as 
>1 second of the track has elapsed) and
pressing it multiple times will move you back
one track at a time. Holding any Skip button
pressed will fastly scan through all tracks on 
the disc.

The Skip buttons may be used when the HD 755
is either playing or stopped. If the unit is
stopped, the Skip buttons may be used to locate
the first track to be played. The Play button 4
9 must be pressed to begin play. If the Skip
buttons are used while the unit is already play-
ing (as described above), the audio output will
stop while the new track is located, and play will
automatically resume after the Skip button is
released.

If the Skip buttons are pressed when program
play is in use (see page 13), the unit will move
from one programmed track to another.

This feature lets you locate a track by playing the
first 10 seconds of each track, up from the track
playing or selected actually. When the Intro
button 9 on the front panel is pressed, the unit
will play only 10 seconds of each track, and then
automatically move to the next track. When you
have reached a track that you wish to listen to in
its entirety, press the Intro button again to
resume normal operation. When the Intro
feature is activated, the INTRO indicator will
illuminate in the Information Display % to
remind you that Intro Search is in use.
