Order of files
The unit plays the files in the order that the writing software
writes them. Therefore, the playing order may not be the same
as the order you input. The playback order of the folders and
files is as follows. However, the folder and file playback order
differs from the folder no. and file no. indicated on the display.

Terminology
Bit rate
This is the "sound" compression rate specified for encoding. The
higher the bit rate, the higher the sound quality, but also the larger
the files.
Sampling rate
This value shows how many times per second the data is sampled
(recorded). For example, music CDs use a sampling rate of 44.1
kHz, so the sound is sampled (recorded) 44,100 times per second.
The higher the sampling rate, the higher the sound quality, but also
the larger the volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files
into the specified audio compression format.
Tag
Song information such as track titles, artist names, album names,
etc., written into MP3/WMA files.
MP3: ID3 tag
WMA: WMA tag
Root folder
The root folder is found at the top of the file system. The root folder
contains all folders and files.

1
Press Rotary encoder (MODE) repeatedly to
choose the desired mode.
Each press changes the modes as follows:
BASS → TREBLE → SUBW* → BALANCE → FADER →
DEFEAT → VOLUME → BASS
Bass : –7 ~ +10
Treble : –7 ~ +7
Subwoofer : 0 ~ +15
Balance : L15 ~ R15
Fader : R15 ~ F15
Defeat : OFF/ON
Volume : 0 ~ 35
• If the Rotary encoder (MODE) is not pressed within 5 seconds
after selecting the BASS, TREBLE, BALANCE, FADER, DEFEAT
or SUBWOOFER mode, the unit automatically returns to normal
mode.
* When the subwoofer mode is set to OFF, its level cannot be
adjusted.
2
Turn the Rotary encoder until the desired sound
is obtained in each mode.
By setting Defeat ON, previously adjusted settings of
BASS and TREBLE will return to the factory defaults.
• Depending on the connected devices, some functions and display
indications do not work.

Turning Loudness On/Off

Loudness introduces a special low- and high-frequency emphasis at
low listening levels. This compensates for the ear's decreased
sensitivity to bass and treble sound.
Press and hold the Rotary encoder (MODE) for at
least 2 seconds to activate or deactivate the loudness
mode.
The display shows "LOUD ON" when the loudness mode is
activated.
