Take your Internet music on the road with the CHA-S634 CD changer! This 6-disc changer's sound quality is outstanding — it uses the same premium-grade audio processor as Alpine's DVD players.

In addition to your audio CDs, CD-Rs and CD-RWs, it'll play MP3 files stored on disc (up to 200 files per disc). Six MP3 discs can hold about 60 hours of music — that's ten times more than standard CDs. For easy identification, you can name up to 80 of your discs for display on a text-compatible Alpine receiver. And the CHA-S634 can decode MP3 ID-3 tags or CD Text info.

Please note: This changer's control cable is compatible with Alpine Ai-NET-controlling receivers. An inexpensive adapter is required if you want to use the CHA-S634 with Alpine older, M-Bus changer-controlling head units.

More details on the Alpine CHA-S634

Research Team

Product Research


Compatibility: This changer is directly compatible with Ai-Net equipped Alpine changer controllers, and, when used with the optional KCA-130B adapter cable (sold separately), it will work with M-Bus (Mini-Bus) equipped Alpine changer controllers. When used with a M-Bus equipped controller, some MP3 functions, such as folder skip up/down, may not be available.

Suspension: The CHA-S634 has a high speed, anti-vibration mechanism with silicon oil dampers for skip-resistant performance.

"M DAC" D/A Converters: This changer uses two "M" Digital-to-analog converters (M DAC's). This type of DAC is exclusive to Alpine and is a hybrid of a 1-bit DAC and a multi-bit DAC. With this type of DAC, clock timing isn't as crucial as in 1-bit DAC's and cost can be kept down without losing the linearity and error free performance of most 1-bit DAC CD players.

Mounting: This unit may be installed vertically, horizontally, or at an angle between 0 and 90 degrees. There are 5-position angle settings on both sides of the unit that must be set to agree with the mounting angle of the unit.

CD-R/CD-RW: This changer will play CD-R and CD-RW discs.

MP3 playback: This changer can play MP3 files, and it will support ID3 tags associated with the files.

Random Playback: This changer allows for random play on one disc only (the M.I.X. One Function). This unit does not support the ALL M.I.X. function (random play of all discs). Even though the ALL M.I.X. function is one that Ai-Net controllers can typically access, it is not available when using this changer.

CD Text: When playing CD Text encoded CDs, this changer will transmit the data for display on compatible Alpine head units equipped with CD Text display capability.

Disc Naming: When used with a compatible head unit, the changer allows Disc Naming for 80 discs.
