CD RECORDING  19

Making recordings on the CDR 25 is simple and
easy once you become accustomed to the basics
of CD Recording. Before making your first
recording, please take a moment to review the
CDR Basics on page 14. In particular, you will
need to become familiar with the types of discs
that may or may not be used in the CDR 25. In
addition, some terms used in the following
pages may be new to you. The following defini-
tions and information will help you to make CD
recordings using the CDR 25’s many features:

The CDR 25 accepts analog inputs and digital

coax or optical inputs. Before making a record-
ing, be certain that you have selected the cor-
rect input.

After a disc is recorded, it must be finalized.

This process adds the final table of contents
data to the disc and makes it playable on
other machines. Until a disc is properly final-
ized, it may not be played on any other
machine or the Play Deck 3 of the CDR 25.

The CDR 25 may record on either CD-R or 

CD-RW discs, but they must be of the type
specifically designed for use in consumer-audio
CD recorders. These discs may be recognized
by looking for the words “Digital Audio” in the
compact disc logo on the blank disc or its
packaging. Discs with the logo reading only
“Compact Disc/Recordable” are designed for
computer data recording, and they will NOT
work in the CDR 25.

CD-R discs may not be erased or have material

added to them once they have been finalized.

At least four (4) seconds of blank recording

time must remain on an unfinalized disc for
recording to take place.

• The maximum number of tracks that may be

recorded on a disc is 99.

• Note that some CD-R/CD-RW audio recording

discs may be used for single-speed recordings
only. If you use a disc with such a warning,
make certain not to dub at that 2x or 4x
speed. However, the CDR 25 has been tested
for compatibility with a wide range of blank
discs from manufacturers throughout the
world. In most cases, blank discs will produce
high-quality recordings at any dub speed.

• In some rare cases, a CD player may not be

compatible with CD-R discs. If you find that a
CD-R disc plays in some players but not in oth-
ers, the fault is most likely with the player, not
with the recorded disc or the CDR 25.
Remember that CD-RW discs made in the CDR
25 will play only in CD players that are special-
ly designed to accommodate CD-RW discs.
Note that most DVD players are compatible
with finalized CD-RW discs.

Some commercial CD discs may contain a copy

protection data bit that will prevent a digital
copy of the disc to be dubbed. In that case, the
CDR 25 will attempt to make an analog dub.

This product is equipped with the Serial Copy

Management System (SCMS) to protect the
rights of copyright owners. As a part of this
system, it is possible to make a copy of most
CDs for your own personal use. However, it is
not possible to make a digital copy from
another digital copy. It is possible to make an
analog copy of a digital copy (see page 21).

The CDR 25 will not copy DVD discs, computer-

data discs, CD-based computer or video-game
discs, or digital audio discs with a sample rate
that is not compatible with the range of the
CDR 25s sample-rate converter.

Recordings on the CDR 25 may be made in a
number of ways:

Discs may be dubbed using the playback deck

on the CDR 25 as a source. These copies may
be made in real time, at twice normal speed,
or at four times normal playback speed.

Recordings may be made from an external CD

player or other digital source that is synchro-
nized with the dub being made in the CDR 25.

Recordings may be made from any compatible

external digital source.

Recordings may be made from an external

analog source.

CD-RW discs may not be erased and reused

more than 99 times. This is a limitation of the
CD-RW format, not a fault of the CDR 25.

Disc Dubbing 
The easiest way to make a copy of an entire disc
is to use the CDR 25’s internal dub capability.

1. First, insert a blank or unformatted disc in the

Record Drawer %. When the disc is insert-
ed, the CDR 25 will examine it to determine if
it is a CD-R or CD-RW disc, and optimize itself
for the best possible recording. This is indicat-
ed by OPC message in the Information
Display K.

2. Place the disc to be dubbed in the Play

Drawer 3 and wait until the Table of
Contents data is read and the Information
Display K shows the track and running time
data for the disc.

3. Next, select a dub speed. The default speed is

x4 dub, where the recording takes only 1/4th
of the actual running time of the disc.
However, with the CDR 25 you may also
select 2x dubbing or real-time dubbing. Press
the Speed button

I# to select a speed

as indicated by the 2x/4x Indicators F.
When no Speed Indicator lights, the unit is set
to real-time recording. Note that the slower
the record-dub speed, the more tolerant the
unit is of errors on the blank or played disc.
However, with most high-quality blank discs,
the 2x and 4x speeds should not present a
problem.

4. Before beginning a dub, make certain that

there is sufficient blank space on the record
disc. To do this, first determine the time avail-
able on the blank disc by subtracting the time
of previously recorded material, if any, that is
shown in the record side Information
Display K from the total time available on
the disc. That number should be greater than
the total time of the disc to be dubbed, which
is shown in the play side Information
Display K.

5. When you are ready to start the dub, press

the Dubbing Button l). During this
process the Dubbing Indicator H will
light, the Record Indicator T will flash and
a B U S Y message will flash in the Record
Deck’s Information Display K.

6. When both Information Display Indicators

return to normal, with indications of 0 1
0 0 : 0 0

, press the Play/Select Button

j*˘ to start the dub.

While the dub is in progress, you will see the
track numbers and running time increase as 
the disc is copied. The Level Indicators will also
flash but this is only for your reference, as record
levels may not be adjusted during digital record-
ings. It is possible to listen to the source disc
while it is being dubbed by selecting the 
appropriate input on your receiver, preamp or
processor.

Important Note: When a high-speed (2x or 4x)
dub is being made, you will hear the playback
from the CDP outputs £∞• at the faster
speed. Fast speed playback increases the pitch
of a sound, and when played back at high vol-
ume levels this may damage your speakers. DO
NOT use high volume levels when listening to
high-speed dubs while they are in progress.

The dub will stop automatically when the source
disc has played through to the end. If you are
adding additional tracks to a disc that has not
yet been finalized, UPDATE will flash in the
Information Display K. After the dub is
finished, the CDR 25 will return to normal
operation. To manually stop a dubbing
operation, press the Stop button

N&¸

for either deck.

7. 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 instruc-
tions on disc finalization.
