Alpine CDE-9841R Manuale Utente

This product can playback CDs containing both CD and MP3/WMA
data. However, in some situations (some enhanced CDs), playback
may be difficult. For these special cases, you can select playback of
CD data only. When a disc contains both CD or the MP3/WMA data,
playback starts from the CD data portion of the disc.

CD-DA

: Only CD data can be played back.

CDDA/MP3 : Both CD data and MP3/WMA file tracks can be

played back.

When an external amplifier is connected, sound quality can be
improved by stopping the power supply of the built-in amplifier.

POWER IC OFF : Use this mode when the front pre-amplifier
of the unit is used to drive an external amplifier connected to
the speakers. In this setting, the head unit’s internal amplifier
has no output to drive speakers.

POWER IC ON : The speakers are driven by the built-in
amplifier.
