Notes:
"
In monaural recording, the sound on the right and left
channels is mixed even if the input source is in stereo.
Although you can hear the stereo sound from the ear-
phones, the recorded sound is monaural.
"
Tracks recorded in 2 times long recording and 4
times long recording modes cannot be played with
the unit that does not support these modes. On
such a unit, no sound is heard. (The operation may
vary depending on the unit.)
"
Tracks recorded in monaural cannot be played on a
unit that does not support monaural playback.

About ATRAC
The ATRAC (Adaptive TRansform Acoustic Coding) sys-
tem compresses the sound data into 1/5 by cutting out
the inaudible sound. Since the sound is selected based
on psychoacoustics masking, the sound quality is not
impaired. This unit is equipped with the ATRAC3 com-
pressing system that can reduce the sound data to 1/10
or 1/20 of its original size. By employing this system, 2
times and 4 times long recordings are enabled in stereo
mode.

About the recording mode
You can select the recording mode from stereo recording,
2 times long recording, 4 times long recording, and mon-
aural recording. Recordable time varies depending on
the recording mode. If the tracks are recorded on an 80-
minute MiniDisc, its recording time changes as follows:

Caution for 4 times long recording
(LP4)
Special compression methods are used to achieve 4
times long recording. This may cause some noise to be
recorded occasionally. When the highest quality is
required, stereo or LP2 recording is recommended.
