CD RECORDING  21

If you wish to make a dub with the tracks in a

different order from the original disc, omit
tracks on a disc, or make a dub that mixes
tracks from different discs, create a Program-
Playback List before pressing the Play/Select
button 

9* to start the dub. Instructions for

creating a Program List may be found on page
18. NOTE: Dubs containing Program Lists may
only be made at the 1x speed. If you attempt
to make a Programmed Dub at the x2 or x4
speed, the unit will automatically select the 
x2 speed.

The Pause buttons do not operate while a dub

is in progress.

Tracks will be added automatically to mirror

the track structure of the original disc.

The Total Time indication of the recorded CD

may vary slightly from the original due to vari-
ations in the spin speed of each drive, but this
is normal. No information has been lost in the
recording process.

If the original disc being dubbed is a digital

copy or if it contains copy-prohibit signals, the
unit will automatically make a copy using an
analog output from the disc.

CD Sync Recording
CD Sync recording allows you to make an auto-
matic digital recording from an external CD play-
er or MD. During CD Sync Recording, the record
unit starts in sync with the source, and tracks are
added automatically.

To make a CD Sync recording: First, make certain
your playback source is selected and cued to the
correct starting point. Next, select the appropri-
ate digital input by pressing the Input button
L until the desired COAXor OPTI-
CAL

indication appears in the Record Deck

Information Display K. CD Sync recordings
may not be made from an analog input.

Next, make certain that there is a fresh disc in
the Record Drawer for the recording. Press the
CD Sync button

M9 and note that the Sync

Indicator I will light and the Record
Indicator T will flash. Select the type of
recording to be made:

To record only the first track from the source

player, press the CD Sync Button so that 
1 TRK

appears in the Record Deck

Information Display K.

To record the entire disc, press the CD Sync

Button so that ALL appears in the Record
Deck Information Display K.

When the desired mode has been selected, start
the playback from the source machine. The CDR
20 will automatically recognize the incoming
digital data and begin recording, while the track
numbering from the original disc will be carried
over to the dub.

If the playback source is NOT a CD, you will have
to increment the tracks manually.

The recording will continue until the CDR 20
senses that the playback is finished when there
is no incoming signal for more than three sec-
onds. At that point the recording will stop.
You may also stop the recording at any time by
pressing the Record Deck Stop button
N&. When there are only four seconds
remaining on a blank disc, DISC FULL
message will appear in the Information
Display K. 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 22.

After the recording is complete, an UPDATE
message will appear briefly, and the unit will
then return to normal operation. Remember to
Finalize the recorded disc so that it may be used
in other machines.

Recording from an External Source
To record from any external source, first place a
CD-R or CD-RW audio disc in the Record Deck
%

. Next, select the input to be used by pressing

the Input button 

L. Pressing the button

will cycle between the input choices, which will
be shown in the Information Display K as
COAX

, OPTICAL or ANALOG. In addi-

tion, the Digital Indicator Y will light when
the coax inputs ise selected, and the Analog
Indicator X will light when the analog inputs
are selected.

Note that when the digital input is selected, the
connection may be made to either the rear panel
Coax Input § or the Front-Panel Digital
Input 6. If a signal is present at both coax
inputs when a recording is made, the front-panel
input will be used as the source.

Press the Auto/Manual button 

C to select

how tracks will be numbered on the recorded
disc.

• The default mode is Manual. In that mode for

either digital or analog recordings, you must
add track numbers manually by pressing the
Track Increment button 

D when you wish

to increase the track number.
This mode is recommended for recordings
made from analog sources.

The Auto mode will add track numbers auto-

matically, in one of two ways: When track data
is present from a digital recording, it will be
carried over to the new copy disc. Thus, when
the CD being played moves from one track to
the next track, the copy disc will also increase
the track number by one. Activate the Auto
mode by pressing the Auto/Manual button
C once and note that the Auto Indicator
W

will light.

• In the Auto mode for recordings from an ana-

log source or a digital source with no track
data, the track number will be increased when
the CDR 20 receives silence for 3 seconds.
After 5 seconds of silence, the recording will
stop. To activate the Auto mode, press the
Auto/Manual button 

C once and note that

the Auto Indicator W will light.

To prepare for a recording, press the Record
button

J8. The Record Indicator T will

flash, and the word BUSY will briefly appear in
the Information Display K. When the
Display returns to the track and running-time
information, the unit is ready to record.

Once the source material is playing, start the
actual recording by pressing the Play/Select
button

9*. Note that the Record

Indicator T will stop flashing and the
Information Display K will begin to show
the running time of the recording and the track
data. Depending on which mode of track incre-
ment has been selected as described above,
track numbers must be increased manually or
they will be added automatically. Regardless of
which mode has been selected, a track may be
added at any time by pressing the Track
Increment button

D.

Note: If there is a pause in the playback signal
for more than 5 seconds for digital recordings or
10 seconds for analog recordings, the CDR 20
will stop the recording. Also, when the Pause
button is pressed during a recording, the track
number will increase by one number and the
recording will stop and must be restarted by
pressing the Play/Select button

9*. When

the recording is finished, press the Stop button
&

N.

Unlike conventional analog tape recorders, the
CDR 20 does not require level setting when
recordings are made from a digital source.
Although the Level Indicator C will operate,
this is only informative and the level may not be
changed or adjusted. However, when you are
making a recording from an external analog
source such as a cassette recorder or the analog
output of a receiver or preamp, you should
adjust the input levels using the Record-Level
Control ^. Adjust the levels so that the
blue/white segments of the display are almost
all lit, and the red segments flash only occasion-
ally. If the red segments are constantly lit,
the recording will be distorted and produce un-
acceptable quality.

22 CD RECORDING

To stop the recording, press the Stop button
N&. The recording will automatically stop if
it takes more space than is available on the 
CD-R/RW disc. A DISC FULL message will
appear to remind you that a new disc is needed.

At the end of a recording, a BUSY message
and an UPDATE message will appear briefly,
and the unit will return to normal operation.
Remember to Finalize the disc after recording so
that it may be used in other players.

Finalizing CD-R and CD-RW Discs
Finalizing is a simple process that completes the
recording of a disc so that it may be used in
other players. When a recording is finished, a
disc must be Finalized. Once that is done, a 
CD-R disc may not be changed or added to. CD-
RW discs are “locked” once they are Finalized,
and they must be Unfinalized to permit addition-
al recording or erasure.

To Finalize a disc, place it in the Record
Drawer %. Once the disc’s Table of Contents
information has been read and the OPC process
has been completed, press the Finalize button
E@ and note that the Finalize Indicator
U

will begin to flash. Within three seconds,

press the Select button

9* and note that

the Finalize Indicator U will stop flashing.

The Finalization process will take up to two 
minutes, depending on the length of material
recorded on the disc. During the Finalization
process the Record Deck will not accept any
operating commands.

When the Finalization process is complete the
Finalize Indicator U will go out, and the
R/RW Indicator P will also go out as an indi-
cation that the disc is now playable on other
players. The CD Indicator S will remain lit.

Unfinalizing and Erasing CD-RW Discs
CD-RW discs are unique in that they are both
recordable and rewritable. This means that you
may use them over again like a cassette tape.
However, the process of reusing a CD-RW disc is
slightly different from that used with tapes.

Unfinalizing a CD-RW Disc
To keep the material that is already recorded on
a finalized CD-RW disc but to add an additional
track and erase single tracks, you must first unfi-
nalize the disc. To do that, place the CD-RW disc
in the Record Deck % and wait until the Table
of contents data has been read.

Press the Erase button

K! twice and check

to make sure that the Erase Indicator V
flashes and the word TOC appears in the
Record Deck Information Display K.
Within three seconds, press the Select button
9* to start the process. The Erase
Indicator V will remain lit and stop flashing,
and the Information Display K will switch to
OPC

and then back to TOC.

When the process is finished, the Erase
Indicator V

will go out, and the display will

return to normal. The disc is now ready to have
single tracks removed or additional tracks
added.

Erasing an Entire CD-RW Disc
Erasing the entire contents of a disc is simple,
and it does not matter if the disc has been final-
ized or not. To erase the disc, press the Erase
button

K! twice if the disc has NOT been

finalized and once if it has been finalized, so
that the word DISC appears in the
Information Display K and the Erase
Indicator V flashes. To start the erasure, press
the Select button

9* and note that the

Erase Indicator V will stop flashing. The era-
sure process takes about a minute, and it is com-
plete when the Information Display resets to
00 00

:00 and the Erase Indicator V goes

out. The disc is now totally erased and may be
reused.

Erasing a Single Track
The individual tracks on a CD-RW disc may be
erased one at a time, starting with the last track
on the disk, or you may erase more than one
track. Note that before individual tracks may be
erased the disc must be unfinalized. If the disc is
finalized, follow the instructions above for unfi-
nalizing before proceeding with these steps.

To erase only the last track, press the Erase 
button

K!. Note that the Information

Display K will display 01 TRK and the
Erase Indicator V will flash. Press the
Play/Select button

9* within three sec-

onds and note that the Erase Indicator will stop
flashing. When the Erase Indicator V goes
out the Information Display K will show the
total number of tracks that now remain on the
disc.

You may erase more than one track, counting
backwards from the last track. First, press the
Erase button

K!. Note that the Information

Display will display 01 TRK and the Erase
Indicator V will flash. Press the Next button
PÓ or Previous button 8Ô until the
number of tracks to be erased appears in the
Information Display K. For example, when
0 6 T R K

appears in the display a total of six

tracks will be erased, counting back from the
last track on the disc. Next, press the
Play/Select button

9* within three sec-

onds of making the track selection and note that
the Erase Indicator V will stop flashing.
When the Erase Indicator V goes out the
Information Display K will show the total
number of tracks that now remain on the disc.

Important Note: Tracks at the beginning or in
the middle of the disc may not be erased until all
of the discs after them have been erased.

Important Note on Erasure and
Finalization Times: Regardless of the speed at
which a disc was recorded, the CDR 20 will
erase and finalize discs at the x4 speed to mini-
mize the length of the process. However, in some
cases it may be necessary for the unit to repeat
the erasure or finalization due to the nature of
an individual disc. For that reason, it is normal
for the time required to complete these steps to
vary from one disc to another.
