About AUDIO on CD-ROMs

There are three types of Audio that you will find on CD-ROM discs:

CD-DA Compact Disc Digital Audio (Conforms to the Red Book Standard)

Compressed Audio (ADPCM, Adaptive Pulse Code Modulation). Conforms to the Yellow Book Standard and is found on CD-ROM discs.

Compressed Audio (ADPCM) that is interleaved with computer data and found on CD-ROM XA discs.

Compact Disc Digital Audio is high quality audio you’re probably familiar with on audio compact discs (CDs). This audio is output through the RCA jacks on the back of the Pioneer CD-ROM Changer. Cables from these RCA jacks can be connected to an amplifier and speakers or to powered speakers. You can also hear the audio through headphones connected to the headphone jack on the front of the unit.

Compressed Audio found on most CD-ROMs requires that a Sound Card be installed in the computer. The drive transfers the compressed audio data to the host computer for decompression and conversion through the sound card. The sound card processes the audio through the computer and outputs the audio through jacks to an amplifier and speakers or to powered speakers.

Check with the publisher or distributor of the CD ROM product to determine if it uses CD-DA or compressed audio. Remember if the CD-ROM product outputs compressed audio, you will need a sound card in your computer to hear the audio.

Kodak Photo CDs - Single Session/ Multi-Session

Pioneer CD-ROM Changers are Kodak Photo-CD compatible and can read multi-session Kodak Photo-CDs. Multi-session Photo-CDs are those where sets of photographs are encoded onto the disc at different times. Single-session Photo-CDs have only one set of photos on the disc, encoded at one time. A program that will open Photo-CD files for viewing is also required, such as Kodak Viewer, Aldus PhotoShop, QUICKTIME for the Macintosh, or Microsoft Video for Windows.
