ADVANCED FEATURES

MP3 File Search System and CD TEXT MP3 File Search System allows you to locate in seconds hundreds of MP3 tracks on a CD-R/RW by artist name, song title or folder. In addition, MP3 ID3 Tags and Audio CD Text are supported on a large, easy-to-read dot matrix fluorescent tube display. Memo Points With 1000 memo points on-board, the DN-D4500 can store your Loops and Hot Starts on any audio CD track and recall them at a later time when that track is cued in either CD drive. Cueing Accuracy and BPM Counter Precision cueing to frame sound accuracy can be set quickly and easily using the inner 50mm jog wheel with the outer shuttle ring for user-adjustable quick jumps while scanning. The inner jog wheel also controls pitch bend, which is essential for synchronizing tracks for beat mixing a DJ skill aided by the built-in automatic BPM counters. Key Adjust and Shock-Proof Memory The Key Adjust feature keeps vocals and music sounding true even when you adjust the speed of the track. With up to 100 seconds of anti-shock memory for MP3 and 20 seconds for audio CDs, your groove will not be interrupted by either sound or vibrations. Relay Play with Adjustable Overlap Background music no longer has to have silence between tracks. The unit can go straight into Play mode when it is powered up. Music can also be played alternately from two discs using Relay play, which will start the next track several seconds before the previous track finishes.

Creating databases

Creating databases q At the top menu in the Utility mode, turn the PARAMETERS knob or JOG disc and select Create. Press the knob again to enter. w The unit is set to the mode for creating databases.
Creating temporary databases
Use this procedure to create a database searchable by file name only. This database can be created faster than a full database. Searching using ID3 Tag data is not possible. Creating temporary databases q At the top menu in the Utility mode, turn the PARAMETERS knob or JOG disc and select Temporary. Press the knob again to enter. w The unit is set to the mode for creating the temporary database. Selecting the device q A list of the currently connected devices is displayed on the left side of the screen. w Turn the PARAMETERS knob or JOG disc and select the device for which you want to create a temporary database. A message asking whether you want to create a temporary database or not pops up at the bottom left of the screen. q When OK is selected: Creation of the temporary database for the device set in step 2 starts. A progress bar is displayed, showing you the progress of the temporary database creation operation. An indicator indicating that a temporary database is being created is displayed even while playing MP3/WAV files. e When Cancel is selected: The temporary database for the device set in step 2 is not created and the screen returns to as it was in step 2.
MP3/WAV files stored on devices other than the one for which the database is being created can be played even while the database is being creating. In this case, however, resources are required to process the file playback operation, so the time required to create the database may increase substantially. Also, when a database is created on a device, the database is reset, so any playlists created for that device are deleted.

Setting the Database Edit mode
At the top menu in the Utility mode, turn the PARAMETERS knob or JOG disc and select Database Edit. Press the knob again to enter. Selecting the device q A list of the currently connected devices (with database) is displayed on the left side of the screen. w Turn the PARAMETERS knob or JOG disc and select the device for which you want to create the database. Press the knob again to enter.
The Database Edit list is displayed.
It is possible to create databases even for devices for which a database already exists. Doing so, however, creates a new database, so playlists created up to that point are deleted. A message asking whether you want to create the database or not pops up at the bottom left of the screen. When OK is selected: Creation of the database for the device set in step 2 starts. A progress bar is displayed, showing you the progress of the database creation operation. An indicator indicating that a database is being created is displayed even while playing MP3/WAV files. When Cancel is selected: No database is created for the device set in step 2 and the screen returns to as it was in step 2.
