13 INSTALLATION AND CONNECTIONS

Batteries
Insert the two AA batteries supplied with the
CDR 30’s remote by turning the remote over so
that the bottom of the remote is facing towards
you. Gently lift the plastic tab on the battery
cover up and away from you, and lift the lid off.
Insert the batteries in the remote, being careful
to follow the + and – polarity indications in the
bottom of the compartment. Replace the cover
by first seating the two small tabs into the mat-
ing holes at the top of the remote, and then
gently push the cover down until the latch
snaps into place with an audible click.

NOTE: When replacing batteries, it always a
good idea to replace both at the same time.
When the remote will not be used for an
extended period of time, it is also a good idea
to remove the batteries to avoid the possibility
of damage due to corrosion. Batteries contain
chemical substances and we recommend that
you dispose of them properly and in compliance
with any local regulations.

IR Remote Connections
If the CDR 30 is installed behind a cabinet or
other obstruction that may block the path
between the front panel Remote Sensor 

¯

and the location where you will use 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 CDR 30
to send commands to other compatible remote
products. Connect the Remote IR Out Jack
⁄ to the input of the other product or system.

Power Connections
Connect the AC Power Cord ¤ to an AC
power source. The CDR 30 uses sensitive, high-
performance computer-grade CD drives, and to
protect them we recommend that you consider
the use of a surge protector, just as you would
for a computer.

If the rear panel AC outlet on a receiver or
other product is used, make certain that it 
provides at least 28 watts, and that the total
power of all products connected does not
exceed the maximum rated output of the prod-
uct containing the outlets. If the CDR 30 is con-
nected to a switched outlet, remember to turn
on the outlet or product controlling it in order
for the CDR 30 to operate.

14 CD RECORDING BASICS

CD Recorders (CDRs) are similar to standard CD
players, with the addition of the features and
controls needed for recording. Functions such
as play, search and programming for playback
will be familiar, but the recorder will function
slightly differently than what you may be used
to for magnetic tape recorders.

Disc Types
Unlike a conventional CD player, the CDR 30
uses three types of discs, and it is important to
understand how each one plays.

Both decks in the CDR 30 will play

back any conventional CD that bears this logo.

Discs that bear this logo may be

recorded on one time, and when they are final-
ized they will play in either deck in the CDR 30
or in any conventional CD player, including
home, car and portable models. The Record
Deck

% on the CDR 30 may also be used 

to record on these discs, and it will play 
CD-R/Audio discs even if they have not been
finalized.

Discs that bear this logo may be used

for recording on the CDR 30, and they may also
be erased and reused. They may be recorded on
or played on the Record Deck

% of the 

CDR 30 and in other CD-RW recorders or 
CD-RW compatible players. They will NOT play
back in most current CD players unless the
player is CD-RW compatible. CD-RW Audio
discs will play on most DVD players once they
have been finalized.

Discs designed for use in

computer CD-R drives may not be used for
recording in the CDR 30. Only discs specifically
designed for use in consumer CD audio
recorders may be used. If you attempt to 
use a blank-computer-type recordable disc for
recording on the CDR 30 you will see a
NO AUDIO message in the Time/Message
Display

F and recording will not be possible.

However, discs that have been recorded in the

CD-R drive of a computer may be played in the
CDR 30, provided that they have been properly
finalized in accordance with audio standard
IEC958.

Note that the CDR 30 is specifically designed
for the recording and playback of consumer
audio discs, and cannot be used to copy data
discs, DVD discs, or other optical discs used by
video- or computer-game systems.

Digital Source to CD Audio: Depending on
the particular input source used, the CDR 30
will make a CD Audio disc when fed a signal
from a digital source such as an external CD or
DVD player, MiniDisc or DAT player. When the
input signal is not at the 44.1kHz standard used
by digital audio discs it will be converted to the
proper standard by the CDR 30’s built-in sample
rate converter. Input signals will be transferred
directly to the copy disc as a digital signal, provided
that it is an original recording. Digital sources
that are copies will first be converted to an
analog signal and then back to a digital signal
for recording. This is a requirement of the SCMS
system, which is part of the CD recording system.

When the dubbing is one using the dual-deck
capability of the CDR 30 the copies may be made
in real time, or at twice or four times normal.

Analog sources to CD Audio: When the
input signal is a conventional line-level analog
audio signal, such as the record output of a
receiver or processor, it will be converted to digital
data and recorded as a standard CD audio disc.
These dubs may be made in real time only.

MP3 discs to CD Audio: A unique feature of
the CDR 30 is its ability to play discs recorded
with MP3 data files. These discs may be copied
to conventional CD audio discs using the dual-
deck dub capabilities. Note that it is not possible
to copy MP3 discs to additional MP3 disc copies.

The CDR 30 is not equipped to accept external
MP3 files for direct recording or playback.

CDR Terminology and Display Messages
Compact disc recording has its own special 
terminology, and some of the messages 
displayed by the CDR 30 may be new to you.
Before using the CDR 30, you may wish to

familiarize yourself with some of the terms used
by the CDR 30. Additional error message dis-
plays may also appear. Please see page 25 for a
complete explanation of error messages.

Finalize: This term refers to the process
that completes the recording of a disc by
recording a final Table of Contents and preparing
the disc so that it may be played on other
machines. A CD-R disc may not be played on
the CDP deck of other CD players until it is
finalized. However, once the finalization process
is complete, a CD-R disc may not be recorded
on again. Only CD-RW discs may be “Unfinalized,”
so that additional tracks may be recorded on 
a disc.

TOC: Stands for Table of Contents and it
refers to the data recorded on each CD that
tells the player how many tracks are on the
disc, the total time of the disc and the running
time of each individual track. Each time a disc
of any sort is placed in the CDR 30, you will see
a TOC to indicate that the unit is reading this
data from the disc. This is required to copy the
track information to any recording.

OPC: Stands for Optical Processing 
Calibration. When you see this message in the
Time/Message Display

F, it means that the

laser transport inside the unit is making the 
calibrations and adjustments needed so that
the recording process is optimized for the 
specific disc in use.

BUSY: When you see this message, it means
that the Record Deck is completing part of the
record operation. When you see this message,
do not press any buttons; simply wait until the
message clears from the display.

DISC FULL: When there are only four
seconds of record time remaining on a blank
disc, a DISC FULL message will appear
in the Time/Message Display

F. When you

see this message, you will need to stop the
recording process and, when a CD-R is being
recorded, insert a new blank disc or, when a
CD-RW is in use, either use a new disc or erase
existing tracks, following the instructions on
page 24.

15 PLAYBACK BASICS

Playback of CDs on the CDR 30 resembles that
for traditional CD players with a few exceptions
to accommodate the availability of two sepa-
rate playback decks. Before using the CDR 30,
power-up the unit by pressing in the Main
Power Switch

1. Note that the Standby

2 will turn green, indicating

that the unit is on and functioning. At the same
time, the Information Display 

˜ will light,

the Time/Message Display

F will briefly dis-

play HARMAN KARDON CDR 30 and the
legends behind the front panel controls will
also light up.

Once the Main Power Switch

1 has been

turned on, the CDR 30 may be powered-on 
or -off using the remote control. Pressing the
Power-Off Button 

on the remote will

place the unit in a Standby mode, as indicated
by the amber color of the Standby Mode
Indicator

2. To turn the unit on using the

remote, simply press the Power-On Button 

a.

Note that when the unit is in the Standby mode,
it is still drawing power from the AC main 
outlets. To turn the unit completely off, press
the Main Power Switch

1. When the

2 goes out, the

CDR 30 is off and not drawing any power.
When you will not be using the unit for an
extended period of time, such as during a 
vacation, we recommend using the Main
Power Switch

1 to turn the unit 

completely off.

Although compact discs are very reliable, rough
handling may damage them. Avoid scratching
the bottom (nonprinted) side of the discs, as
this will affect playback of standard CDs and
interfere with the recording of CD-R and 
CD-RW discs. It is also a good idea to always
handle discs by their edges to avoid fingerprints
which may also interfere with playback quality
and possibly cause damage to the laser and
lens assembly.

Loading and Unloading Discs
To load a disc, first open the desired CD deck
by pressing the appropriate Open/Close 
Button 

6$c`. The word OPEN will

appear in the Time/Message Display

F.

Always make certain that there is sufficient
room in front of the unit for the disc drawers 
to open. Note that if either disc drawer is
blocked, the drawer will stop at the blocked
position and an ERROR message will appear.
Press the appropriate Open/Close Button
6$c` to reopen the drawer.

Load a disc in the tray with the printed (label)
side facing up. Once the disc is seated, make
certain that it is properly centered within the
tray. When using 3" discs, take extra care to
make certain that the disc is carefully centered
within the smaller ridges in the disc tray.

To close the drawer, press the appropriate
Open/Close Button 

6$c` or gently

press on the outside of the front cover of the
disc tray. When the drawer is closed the word
CLOSE will appear momentarily in the
Time/Message Display

F, and the letters

TOC will begin to flash in the display once the
drawer is completely closed.

If the disc is a standard CD or a finalized CD-R
or CD-RW disc, TOC will flash while the unit
reads the disc’s Table of Contents information.
Once that data is read, the Time/Message
Display

F will show the total number of

tracks and the total time of all tracks on the
disc. The CD Indicator

Q will also light to

indicate that a standard CD is in use.

When an unfinalized CD-R or CD-RW disc is
placed in the Record Deck

%, the letters

OPC will flash once the Table of Contents has
been read. This indicates that the unit is opti-
mizing its circuits for maximum compatibility
with the specific recordable disc in use. The
number and total running time of any tracks
that have already been recorded will appear in
the Time/Message Display

F, and the

appropriate indicator 

Q will light to tell 

you if a CD-R or CD-RW disc is in use.

If a computer data disc is placed in the CDR 30,
a DATA DISC or DISC ERROR mes-
sage will appear, depending on whether or not
the data disc is finalized. Data discs will not
play and cannot be recorded or dubbed on the
CDR 30.

Using the Remote
The CDR 30’s infrared remote control is
designed to operate both CD decks, as well as
control the playback programming and record
functions. To allow for efficient use of the
remote, its operation is different from standard
CD players. Some buttons are dedicated to one
specific CD deck, while others are shared
between the two decks.

No matter which deck is playing, the Play
Deck (CDP) and Record Deck (CDR)
Display

b

and Open/Close Buttons

c` will always send a command to their
respective deck. The other transport and pro-
gramming functions, however, are shared. To
use any of the transport controls, such as Play
j, Stop u, Pause v or the Search
and Skip Buttons

fiwy, the

o or the Programming

eghkp, first press either the

d to command the Play Deck

3 or the CDR Button z to command the
Record Deck

%. When the button is pressed,

a message reading CDP or CDR will appear in
the appropriate Time/Message Display

F

to confirm the selection.

To switch the remote from controlling one 
deck to controlling the other, simply press the
Select Button

dz for the deck you wish

to control at any time.

will show a right-pointing triangle 

› and the

F will show the

track number being played and the running
time of the track. As each new track begins to
play, the track time will reset to 00:00 and
begin to count up for the new track.

NOTE: Remember that unfinalized CD-R or 
CD-RW discs will only play in the Record
Deck

%. If you attempt to play an unfinalized

disc in the Play Deck

3, a DISC ERROR

message will appear to remind you to play the
disc in the other deck.

To go directly to a specific track on a disc, enter
the track number using the Numeric Keys
o. Note that when selecting a two digit track
number, the second digit must be entered with-
in three seconds after the first Numeric Key is
pressed.

F:

P is NOT

lit: The number tracks on the disc and the total
time of the disc.

P is lit:

The total number of tracks.

Note that when there is an MP3 disc in BOTH
decks, both MP3 Indicators 

P will flash.

Also, if an MP3 disc is placed in one of the
decks when the other is already playing an MP3
disc, an MP3 BUSY message will appear in
the disc of the Time/Message Display

F

where the second disc has been inserted.

To play all of the tracks on a disc in random
order, press the Select Button

dz for 

the desired deck, and then press the Random
Button 

k. The unit will briefly examine all 

of the tracks on the disc and the Random
Indicator

A will light. Each track will be

played in a random order until all tracks on the
disc have been played. Note that there will be a
brief pause in between each track as the unit
searches for the next track to play.

To momentarily stop the disc at any time, press
the Pause Button 

vÔ

. When a disc is

paused, the Play/Pause Indicator

L will add

two vertical lines to indicate a paused disc.
Press either the Play Button 

j(

or the

vÔ

to resume playback

at the point where the disc was paused.

When there is only one disc in the unit, it will
automatically stop when all tracks on a disc
have played through. To stop playback at any
time, press the Stop Button 

uÓ

for

the deck in use.

When there is a disc in each deck, the player
will respond in one of two ways, depending on
which way the dual-play setting is activated. In
normal operation, when the disc in one drawer
finishes, the disc in the other drawer will begin
to play. When the Dual Button 

x¸ is

pressed so that the Dual-Play Indicator

D is

lit, each deck will operate as a separate, single-
play CD unit without regard to the status of the
other deck. For complete information on Dual-
Deck and Dual-Play operation, see page 18.

At the end of a listening session, remove the
discs from the decks by following the instruc-
tions shown on the previous page. Do not leave
the disc drawers open when the unit is not 
in use to prevent dust and dirt from entering
the unit and to prevent damage to the disc-
drawer tray.

To place the unit in the Standby mode at
the end of a listening session, press the Power-
Off Button 

. The POWER OFF mes-

sage will appear briefly in the Time/Message
Display

F, any open disc trays will automati-

cally close, and the Standby Mode Indicator
2 will turn amber.

MP3 Playback
The CDR 30 is unique among consumer audio
CDR/RW recorders in that it plays discs recorded
with MP3 data. It may also make conventional
CD Audio copies of these discs when they are
dubbed using the CDR 30’s dual-deck capabilities.
Since MP3 discs may appear in two different
forms, their playback may require different
operation.

When a disc has been recorded ONLY with MP3
data, simply insert the disc in the CDR 30 as
you would for any CD. After the disc’s Table of
Contents (TOC) data has been read, the MP3
Indicator 

P will light to indicate that an MP3

disc is in use.

When discs are recorded on a computer, it is
possible to place both standard CD Audio and
MP3 tracks on the same disc. These are known
as “Mixed Session” or “Multisession” discs.
When they are used in the CDR 30, the default
mode is to play ONLY the standard CD audio
tracks. To play the MP3 data tracks, wait until
the disc’s Table of Contents is read and the
Time/Message Display

F shows the data

for the standard audio tracks. Then, press the
MP3 Button 

rÒ and note that the MP3

P lights above the appropriate deck.

• If the MP3 Button 

rÒ is pressed while

the CD Audio tracks of a Multisession disc is
playing, an MP3 ON message will flash three
times in the Time/Message Display

F and

then playback will stop. Press the Play
Button 

j(

to play back the MP3

tracks.

• If the MP3 Button 

rÒ is pressed while

the MP3 tracks of a Multisession disc is play-
ing, an MP3 OFF message will flash three
times in the Time/Message Display

F and

then playback will stop. Press the Play
Button 

j(

to play back the standard

CD Audio tracks.

When an MP3 disc is inserted into the CDR 30,
the displays are somewhat different than what
you may be used to for standard CD Audio
discs or from traditional CD players. After the
Table of Contents (TOC) is read, the
Time/Message Display

F will display the

total number of tracks on the disc. During play-
back of an MP3 disc, the default display will
show the running time for the track being
played, but not the track number, as is the case
for normal CD playback.
