CD (MX level 1 to 3):
CD mode processes a large amount of data during playback. MX
takes advantage of this large data quantity to reproduce a more
clear, clean output.
CMPM (MX level 1 to 3):
This corrects information that was lost at the time of compression.
This reproduces a well-balanced sound close to the original.
DVD (Video CD) (MOVIE MX level 1 to 2):
The dialogue portion of a video is reproduced more clearly.
(DVD MUSIC):
A DVD or Video CD contains a large quantity of data such as music
clip. MX uses this data to reproduce the sound accurately.
AUX (MX level 1):
Choose the MX mode (CMPM, MOVIE, or MUSIC) that corresponds
to the media connected.

Press and hold  for at least 2 seconds to return to
normal mode.
Notes
• If  is pressed during setting, the unit returns to the previous item.
• Each music source, such as CD and MP3/WMA/AAC can have its own
MX setting.
• On disks with both MP3/WMA/AAC and CD-DA, when the source
changes from "MP3/WMA/AAC to CD-DA" or "CD-DA to MP3/
WMA/AAC", MX-mode switching may delay playback slightly.
• Setting to Non Effect sets MX mode of each music source to OFF.
• The function is inoperable when DEFEAT is set to ON.
• There is no MX mode for FM, MW and LW radio.
• If an audio processor with the MX function (PXA-H800, etc.) is
connected, its own MX processing is applied to the music source. Since
the processor MX settings may not match the head unit, the audio
processor needs to be adjusted. For details, refer to the Owner's Manual
of the audio processor.
• "CMPM" is applied for MP3/WMA/AAC, Bluetooth Audio and iPod/
iPhone.
