Creating an audio CD
This chapter explains how you can use the CD-RW drive to create an audio CD, and how to play back an audio CD.

Creating an audio CD
On the AW1600, you can select one or more songs on the hard disk, and write the audio data from the stereo track of each song to a CD-R/RW disc in CD-DA format. The CD-R/RW media to which you write this data can be played by the CD-RW drive or a conventional CD player in the same way as any audio CD.

NOTE
Some CD players that do not support CD-R/RW media may not be able to play back a CD you create.

In order to create a CD, you must first register one or more songs in a "track list," and then write the virtual track currently selected for the stereo track of each song (the "current track") to the CD in the order specified by the track list.
A maximum of 99 tracks (areas on CD media to which audio data can be written individually) can be written to one volume of CD-R/RW media, and each track must be at least four seconds long. The maximum length of time that can be written is approximately 74 minutes for 650 MB media, or approximately 80 minutes for 700 MB media.

HINT
The total size of audio data that can be written is 746 MB (approximately 74 minutes) for 650 MB media, or 807 MB (approximately 80 minutes) for 700 MB media.

Types of media that you can use with the CD-RW drive
The CD-RW drive of the AW1600 can use two types of media: "CD-R" which lets you record and add data, and "CD-RW" which lets you erase previously-recorded data and rewrite it. Each type of media has the following characteristics.

CD-R
You can write data to this media, and add additional data later. You cannot erase and rewrite data that has already been written. Once you perform a process known as "finalizing the disc," the audio data written to the CD-R can be played by the CD-RW drive or by most CD players.

CD-RW
In addition to writing and adding data, this media lets you erase all recorded data and rewrite it. Audio data written to a CD-RW can be played back by the CD-RW or by CD players that support CD-RW media.

Methods of writing an audio CD
There are two ways in which you can write audio data to CD-R/RW media.

Track At Once
This method writes the data in units of CD tracks. The advantage of this method is that you can add new data to media that already contains existing data.
With the Track At Once method, the data from the beginning to the end of the stereo track of a song is written to the CD as one track. (Even if there is a portion during the song that contains no data, it will be written as silent audio data.)
Since each track is written individually when you use this method, an interval of approximately two seconds will be created between each track.

In order for a disc written using Track At Once to be playable by the CD-RW drive or a CD player, you must perform a process known as "finalizing" to write track information to the disc. Once you have finalized a disc, you cannot write any more data to it.

Disc At Once
This method writes all tracks at once. Similarly to when using the Track At Once method, the data from the beginning to the end of the stereo track of each song is written to the CD as one track.
However since writing does not stop until all data has been written, there will be no gap between the tracks.

When using Disc At Once to write a CD, you can use the start point, end point and markers that were assigned within the AW1600 song to divide a single continuous song into multiple tracks for writing.
For example, this is convenient when you have recorded a live performance as a single song, and want to assign track numbers while leaving the playback in continuous form.

NOTE
A track shorter than four seconds cannot be written to an audio CD. If you use start point/end point/markers to divide a song into multiple tracks, make sure that each track is at least four seconds long.
If the length of the stereo track exceeds the writable length of the media, you can create an audio CD by adjusting the start point/end point so that the region is within the allowable length. (-> p. 106)

Media that you write using Disc At Once will be finalized automatically, and can be played back by a CD-RW drive or CD player that supports that type of media. However, no further data can be written to a disc that was written using Disc At Once.

Basic settings for the CD-RW drive
Before you actually write data to a CD, you will need to make basic settings for the CD-RW drive.

1	In the Work Navigate section, repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the SETTING page of the CD screen.

1	CD-RW MEDIA ERASE
Erases the data that was written to CD-RW media. For details, refer to "Erasing CD-RW media" (-> p. 109).

2	AUDIO WRITE SPEED
Selects the speed at which audio data will be written to CD-R/RW media.

3	TEST button
Specifies whether a writing test will be performed when you execute writing.

4	WRITE button
Specifies whether the actual writing operation will be performed.

5	UNDERRUN PROTECT button
Enables/disables the function that prevents buffer underrun (an error that can occur when data transfer cannot keep up with writing speed).

6	DATA WRITE SPEED
This indicates the speed at which data other than CD audio (e.g., backup data or WAV files) is written to CD-R/RW media. Normally this will indicate x8. This will indicate x4 if the media supports a maximum writing speed of x4. This field is for display only, and cannot be edited.

7	COMPARE button
If this button is on, the original data will be compared with the backed-up data or the exported WAV file after a backup or export operation is performed, to check whether any errors occurred while writing the data.

2	Move the cursor to the AUDIO WRITE SPEED field, and turn the [DATA/JOG] dial to select the writing speed.
You can select either x8 (eight times as fast as audio playback) or x4 (four times as fast as audio playback). Normally you should use x8, and drop down to x4 if errors occur during writing.
3	Use the TEST button and WRITE button to select the writing operation(s).
The TEST button and WRITE button specify whether a writing test and/or the actual writing operation will be performed. The combination of buttons that are on will determine the operation(s) that will occur, as follows.

Only the TEST button on
Only a writing test will be performed.

Only the WRITE button on
Writing will occur immediately.

Both the WRITE button and TEST button on
First a writing test will be performed, and then the actual writing will be performed.

Depending on the media and the state of the hard disk, it is possible that an error may occur while the data is being written. (If you are using a CD-R, this will make the media unusable.) Thus, you can turn on the TEST button to check whether an error will occur before you actually write the disc. If an error occurs during the test, halt the procedure, and either lower the writing speed or set the UNDERRUN PROTECT button to ENABLE.
4	If desired, set the UNDERRUN PROTECT button to ENABLE.
The CD-RW drive of the AW1600 has a function to prevent "buffer underrun" errors which can occur if data transfer cannot keep up with the writing speed.
If you switch the UNDERRUN PROTECT button to the "ENABLE" setting, this function will be enabled, and buffer underruns will be prevented.

NOTE
If this button is set to ENABLE, the TEST button will automatically be turned off. Also, if the TEST button is turned on, this button will automatically be set to DISABLE.

Writing audio data (Track At Once)
Here's how to use the Track At Once method to write stereo tracks from songs saved on the hard disk to CD-R/RW media. Use this method if you expect to be adding tracks to the disc later, or if you want a two-second gap between tracks.

1	Make sure that the appropriate virtual track is selected for the stereo track of the song(s) you want to write.
Only the virtual track that can be played by the stereo track (i.e., the "current track") will be written to disc. If the correct virtual track is not selected, load that song, use the ST.TRACK page of the MONITOR screen to switch to the correct virtual track, and then save the song.
2	Repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the CD WRITE page of the CD screen.
Immediately after you access this page, the following two buttons will appear in the display.

1	TRACK AT ONCE button
Creates an audio CD using the Track At Once method.

2	DISC AT ONCE button
Creates an audio CD using the Disc At Once method.

3	Insert CD-R/RW media in the drive, move the cursor to the TRACK AT ONCE button, and press the [ENTER] key.
A display like the following will appear.

1	Song list
This is a list of the songs containing stereo tracks that will be written to the CD-R/RW media. The line enclosed by a dotted frame is currently selected for operations. If no songs have been registered, this will indicate "-NO TRACK-".
If audio data has already been written to the inserted CD-R/RW media but the media has not yet been finalized, a title of "--EXIST--" will be displayed for the already-written data.

2	FINALIZE button
Finalizes the inserted media by writing track information to it.

3	INS button
Inserts a new song in front of the song currently selected in the list.

4	NEW button
Adds a song at the end of the song list.

5	DEL button
Deletes the selected song from the list.

6	EXECUTE button
Executes writing to the CD media.

HINT
If you have inserted CD-RW media that contains data written using other than the Track At Once method, a popup window will appear immediately after step 3, asking whether you want to erase the data. If you want to erase the entire media, move the cursor to the OK button. If you want to cancel creation of an audio CD, move the cursor to the CANCEL button. Then press the [ENTER] key.

4	Move the cursor to the NEW button, and press the [ENTER] key.
The song list will show information (track number/song name/size of the stereo track) for the song that will be written to track 1 of the CD.
5	Move the cursor to the dotted frame in the song list, and turn the [DATA/JOG] dial to select the song that will be written to track 1.

NOTE
When you turn the [DATA/JOG] dial, you will see only songs for which the current stereo track contains data.
Songs with a stereo track shorter than four seconds will not be displayed.

6	Repeat steps 4 and 5 to select the songs that will be written to track 2 and following.

HINT
When you move the cursor to the NEW button and press the [ENTER] key, a new song will be added at the end of the existing songs.
By using the INS button instead of the NEW button, you can insert a new song immediately before the song that is selected in the list.
You can use the DEL button to delete the currently selected song from the song list.

NOTE
When you add a song to the song list, the same song will always be initially selected. Change this as desired.

7	Move the cursor to the EXECUTE button and press the [ENTER] key.
A popup window will ask you to confirm.
8	To begin writing, move the cursor to the OK button and press the [ENTER] key.
While data is being written to the media, a popup window will indicate "CD Writing..." When writing is completed, a popup window will ask you whether you want to finalize.

NOTE
If an error message of "BUFFER UNDERRUN!" appears while writing, a buffer underrun has occurred. In this case, either decrease the writing speed to 4x or set the UNDERRUN PROTECT button to the ENABLE position (-> p. 103).
If you enabled the writing test in "Basic settings for the CD-RW drive" (-> p. 103), a writing test will be performed before the data is actually written. If a problem occurs during the writing test, an error message will appear.
Copy-prohibit data will automatically be written into the CD that is created.

9	To finalize the disc, move the cursor to the OK button and press the [ENTER] key.
If you do not want to finalize the disc, move the cursor to the CANCEL button and press the [ENTER] key.
This completes the writing process.

Writing audio data (Disc At Once)
Here's how to use the Disc At Once method to write stereo tracks from songs saved on the hard disk to CD-R/RW media. Use this method if you do not want to create silence between each track of the CD, or if you want to write a single song divided into multiple tracks on the CD.

1	Make sure that the appropriate virtual track is selected for the stereo track of the song(s) you want to write.
2	If you want to divide the song into CD tracks at the marker locations specified within the song, check that markers have been set at the appropriate locations.
3	Repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the CD WRITE page of the CD screen.
4	Move the cursor to DISC AT ONCE and press the [ENTER] key.
The following screen will appear.

1	Song list
This is a list of the songs containing stereo tracks that will be written to the CD-R/RW media. The line enclosed by a dotted frame is currently selected for operations. If no songs have been registered, this will indicate "-NO TRACK-".

2	MARKER button
For each stereo track, this enables or disables the markers that have been set within that song.
When you move the cursor to this button and press the [ENTER] key, the start pint, end point and markers within the currently selected stereo track will be enabled. (A "flag" icon will appear at the left of the list.) If markers are enabled for a stereo track, a track number will be written to the CD at the location of each marker. Regardless of any areas of silence, the entire region from the Start point to the End point will be written.

3	INS button
Inserts a new song in front of the song currently selected in the list.

4	NEW button
Adds a song at the end of the song list.

5	DEL button
Deletes the selected song from the list.

6	EXECUTE button
Executes writing to the CD media.

HINT
If data has already been written on the CD-RW media that you insert, a popup window will appear immediately after step 3, asking whether you want to erase the data. Move the cursor to the OK button if you want to erase the entire media, or to the CANCEL button if you want to cancel execution. Then press the [ENTER] key.

5	Move the cursor to the NEW button, and press the [ENTER] key.
The song list will show information (track number/song name/size of the stereo track) for the song that will be written to track 1 of the CD.
6	Move the cursor to the dotted frame in the song list, and turn the [DATA/JOG] dial to select the song that will be written to track 1.

NOTE
When you turn the [DATA/JOG] dial, you will see only songs for which the current stereo track contains data.
Songs with a stereo track shorter than four seconds will not be displayed.

7	If you want the stereo track of the selected song to be divided into CD tracks at the location of each marker, move the cursor to the MARKER button and press the [ENTER] key.
Markers will be enabled for that song, and a "flag" icon will appear at the right of the list.

HINT
Markers can be enabled/disabled independently for each song.
When you use markers to divide a stereo track, the location of the divisions will be specified in units of 1/75 second.

NOTE
Note that if markers are enabled, the track numbers shown in the list will not match the number of tracks written to the CD.
A maximum of 99 tracks can be written to an audio CD. If, for example, markers are enabled for the song you write to CD track 1, and this song contains 98 markers, it will not be possible to write any more songs to that CD-R/RW media.

8	Repeat steps 5 to 7 to select the songs that will be written to track 2 and following.

HINT
When you move the cursor to the NEW button and press the [ENTER] key, a new song will be added at the end of the existing songs.
By using the INS button instead of the NEW button, you can insert a new song immediately before the song that is selected in the list.
You can use the DEL button to delete the currently selected song from the song list.

NOTE
When you add a song to the song list, the same song will always be initially selected. Change this as desired.

9	Move the cursor to the EXECUTE button and press the [ENTER] key.
A popup window will ask you to confirm.
10	To begin writing, move the cursor to the OK button and press the [ENTER] key.
While data is being written to the media, a popup window will indicate "CD Writing..." When writing is completed, the CD-R/RW media will be ejected, and the following popup window will appear.

NOTE
If you enabled the writing test in "Basic settings for the CD-RW drive" (-> p. 103), a writing test will be performed before the data is actually written. If a problem occurs during the writing test, an error message will appear.
Copy-prohibit data will automatically be written into the CD that is created.

11	If you want to create another CD with the identical contents, insert a new volume of media, and move the cursor to the OK button and press the [ENTER] key.
Writing will begin again.
Alternatively, you can move the cursor to the CANCEL button and press the [ENTER] key to exit the writing process.

Finalizing CD-R/RW media
Here's how to finalize CD-R/RW media that you wrote using Track At Once, so that the disc can be played by a CD-RW drive or a CD player.

HINT
CD-R/RW media written by the AW1600 using Track At Once (and not yet finalized) cannot be played by another CD-RW drive or a CD player, but it can be played by the AW1600's CD Play function. (-> p. 110)

1	Insert the CD-R/RW media that you want to finalize into the CD-RW drive.
2	Repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the CD WRITE page of the CD screen.
3	Move the cursor to the TRACK AT ONCE button, and press the [ENTER] key.
The following screen will appear, and the track list will show the content that has been written to that CD-R/RW media. Already-recorded tracks will be displayed as "--EXIST--".
4	Move the cursor to the FINALIZE button, and press the [ENTER] key.
A popup window will ask you to confirm the finalize operation.
5	To finalize the disc, move the cursor to the OK button and press the [ENTER] key.
If you decide not to finalize the disc, move the cursor to the CANCEL button and press the [ENTER] key.

NOTE
The finalize operation cannot be halted once it has been started. Perform this operation with care.

Erasing CD-RW media
Here's how to erase all data that has been written to CD-RW media, so that the CD-RW disc can be used as a blank disc. You will need to perform this operation on a disc that has been used to store computer data etc. if you want to use that disc on the AW1600.

HINT
Since data is erased as necessary when you back up AW1600 data to CD-RW media or when you write audio data to CD-RW media, you do not need to perform the following procedure each time you re-use the disc.

NOTE
o	The erased data cannot be recovered. Perform this operation with care.

1	In the Work Navigate section, repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the SETTING page of the CD screen.
2	Move the cursor to the CD-RW MEDIA ERASE field, and press the [ENTER] key to select the desired erasure method.
Each button selects the following erasure method.

SIMPLY button
Only the TOC (Table Of Contents) data written to the CD-RW media will be erased. If you select this method, it will take only a short time to erase the CD-RW media.

PERFECTLY button
All data written to the CD-RW media will be erased completely. Since this method erases all data from the media, it will take a longer time than SIMPLY.

Move the cursor to the desired button, and press the [ENTER] key. A popup window will ask you to confirm the erasure.

If you turn on the SIMPLY button

If you turn on the PERFECTLY button

3	To execute the erasure, move the cursor to the OK button. If you decide not to erase the disc, move the cursor to the CANCEL button. Then press the [ENTER] key.
If you selected the OK button, erasure will begin. (This operation cannot be halted.)

Playing an audio CD
You can use the CD-RW drive to play back a conventional audio CD or CD-R/RW media to which audio data has been written. This is referred to as the CD Play function.

HINT
The CD Play function can also play audio data from a mixed-mode CD-ROM (only track 2 and following) or CD Extra (only the first session).

1	In the Work Navigate section, repeatedly press the [CD] key or hold down the [CD] key and use the CURSOR [Up]/[Down] keys to access the CD PLAY page of the CD screen.
In this page you can play back an audio CD inserted in the CD-RW drive.

1	CD PLAY button
Switches the CD Play function on/off.

2	INPUT CH MUTE/MIX button
Use this button to specify whether the signals of input channels 1 to 8 will be output together with the CD playback (MIX button), or whether only the CD signal will be output (MUTE button).

3	List
Displays the tracks of the audio CD that is inserted in the CD-RW drive.

2	Insert the audio CD that you want to play into the CD-RW drive.
3	Move the cursor to the CD PLAY button and press the [ENTER] key.
The CD Play function will be turned on, and the CD track data will be read.
4	To play the CD tracks, press the PLAY key. To stop, press the STOP key.
During playback, the audio output of the CD-RW drive will be sent directly to the stereo output channel. Use the STEREO fader to adjust the volume.
When the CD Play function is on, the keys of the transport section will have the following functions.

(Table)
Key	Operation
PLAY key	Play
STOP key	Stop
REW key/FF key	Rewind/Fast-forward
[DATA/JOG] dial	Select tracks
MARK SEARCH [Back]/[Forward] keys	Select tracks
(Table End)

HINT
When the cursor is located in the list, you can turn the [DATA/JOG] dial to select tracks.
While an audio CD is playing, the access indicator in the display section will blink.

5	To exit the CD Play function, move the cursor to the CD PLAY button and press the [ENTER] key.

NOTE
The CD PLAY button can be switched on/off only while the CD is stopped.
While the CD PLAY button is on, the CD-RW drive will be locked, and it will not be possible to eject the disc.


This is the end of the file.
