Once a playlist has been assembled, creating a Compact Disc is a very simple operation. The first step
in the process is deciding on which format of disc to create. There are two types of Compact Discs that
the ML-9600 can create: Red Book CDs and CD24 CDs.

Red Book CDs (or CD-DA discs, as they are sometimes referred to) are audio Compact Discs that
conform to the Sony/Philips Red Book specification. Almost all commercial audio Compact Discs
available today are "Red Book" CDs, and every standard Compact Disc player in the world will play
Red Book-compliant CDs. Red Book CDs have a sample rate of 44.1kHz, and word lengths of 16-bits. In
order for the ML-9600 to create a Red Book-compliant CD, the CD FORMAT switch (under the CD tray
door) must be set to Red Book.
Because Red Book CDs are limited to 16-bit, 44.1kHz recording, and the ML-9600 allows up to 24-bit,
96kHz recording to the hard disk, Tracks with sample rates higher than 44.1kHz or word lengths
longer than 16-bits will be automatically sample-rate converted and/or noise-shaped down to 16-bit,
44.1kHz files when the CD is created. This will not affect data on the hard disk, which will remain

unchanged at its original sample rate and word length.
CD24™ CDs are special Compact Discs capable of containing and playing back audio files that have
resolutions greater than 16-bit, 44.1kHz. Alesis has combined two non-proprietary standards – ISO-
9660 CD-ROM disc format with AIFF sound files – with proprietary information to create the CD24
standard. CD24 discs can be read by Windows™, Macintosh™, and UNIX™ operating systems, and

DVANTAGES OF
CD24
•
Allows low-cost, random access storage, playback, and delivery of high-resolution audio files.
•
Allows inexpensive backup of audio recorded to the internal hard disk.
•
Allows easy transfer of files to computer-based editing and mastering systems
In order for the ML-9600 to create a CD24 Compact Disc, the CD FORMAT switch (under the CD tray
door) must be set to CD24.

REATING A
CD
Once a playlist has been recorded and edited, creating a CD is a simple task. First, make sure that you
are in HD mode (using the HD/CD LEDs), and make sure the playlist you have currently selected is
the one from which you wish to create a CD. This can be checked by pressing the PLAYLIST SELECT
are in HD mode (using the HD/CD LEDs), and make sure the playlist you have currently selected is
the one from which you wish to create a CD. This can be checked by pressing the PLAYLIST SELECT
button and observing the playlist number and/or the playlist name.
The next step to creating your CD is to choose which type of CD you wish to create; either Red Book or
CD24. This can be changed by pressing the CD FORMAT button.
