21 CD RECORDING

As with all recorded CD-R/CD-RW discs, the
disc must be finalized before it can be played in
other machines. See page 22 for instructions on
disc finalization.

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 

j* to start the dub. Instructions

for creating a Program List may be found on
page 18. NOTE: Dubs containing Program
Lists may be made at either the x1 or x2
speed. If you attempt to make a Programmed
Dub at the x4 speed, the unit will automati-
cally 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 an analog copy.

CD Sync Recording
CD Sync recording allows you to make an auto-
matic digital recording from an external CD
player or MD. During CD Sync Recording, the
0record unit starts in sync with the source, and
tracks are added automatically.

To make a CD Sync recording: First, make cer-
tain your playback source is selected and cued
to the correct starting point. Next, select the
appropriate digital input by pressing the Input
button

v until the desired COAX or

OPTICAL 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

w9 and note that the

I will light and the Record

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 once so that 
1 TRK appears in the Record Deck
Information Display

K.

To record the entire disc or tape, press the CD

Sync Button twice 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 incom-
ing digital data and begin recording. If the
source material is a CD, 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
in 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
x&. When there are only four seconds
remaining on a blank disc, DISC FULL
message will appear in the Information
Display

˚. 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 follow-
ing 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 an 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

v. Pressing the

button will cycle between the input choices,
which will be shown in the Information
Display

K as COAX, OPTICAL or

ANALOG. In addition, the Digital Indicator
Y will light when the coax input is 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

m 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

n 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

m once and note that the Auto

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 sec-
onds. After 5 seconds of silence, the recording
will stop. To activate the Auto mode, press the
Auto/Manual button

m once and note

that the Auto Indicator

W will light.

To prepare for a recording, press the Record
button

t8. 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

j*. Note that the Record

T will stop flashing and the

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

n.

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

j*.

When the recording is finished, press the Stop
button 

&x.

Unlike conventional analog tape recorders, the
CDR 20 does not require level setting when
recordings are made from a digital source.

22 CD RECORDING

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 ana-
log 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 occa-
sionally. If the red segments are constantly lit,
the recording will be distorted and produce
unacceptable quality.

To stop the recording, press the Stop button
x&. 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 final-
ized, but they may be unfinalized to permit
additional 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
o@ and note that the Finalize Indicator
U will begin to flash. Within three seconds,
press the Select button

j* 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

P will also go out as an

indication 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 CD-RW disc but to add an additional track
and erase single tracks, you must first unfinalize
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

u! 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 Play/Select
button

j* to start the process. The Erase

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
finalized or not. To erase the disc, press the
Erase button

u! 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

V flashes. To start the erasure,

press the Select button

j* and note that

the Erase Indicator 

V will stop flashing. The

erasure process takes about a minute, and it is
complete 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 disc, 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 unfinalizing before proceeding with
these steps.

To erase only the last track, press the Erase
button

u!. Note that the Information

K will display 01 TRK and the

V will flash. Press the

Play/Select button

j* 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

u!. Note that the

Information Display will display 01 TRK and
the Erase Indicator

V will flash. Press the

Next button

zÓ or Previous button

iÔ until the number of tracks to be erased
appears in the Information Display

K. For

example, when 06 TRK appears in the dis-
play a total of six tracks will be erased, count-
ing back from the last track on the disc. Next,
press the Play/Select button

j* within

three seconds 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 tracks 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.
