Features

! A P o rtable MD player w it h " Mobile 1-bit

digital amplifier"

"

The 1-bit digital signal is sent to a constant voltage cir­cuit directly from a high-order modulation circuit.
The amplifier transmits and amplifies the signal, and
allows extremely natural and clear sound with little
deterioration.

"

High-quality sound is achieved by vast improvement s
in the sound resolution. The speed and the s mooth­ness of rise of the sound are consequently ensured.

! "4-pole plug earphone" optimizes

"Mobile 1-bit digital amplifier"

"

Sharp has adopted "4-pole plug" earphone that com­pletely separate right and left sound. Enjoy the high
quality sound of the "Mobile 1-bit digital amplifier".

! A Net MD portable recorder

Audio data saved on the hard disk of a PC can be trans­ferred to a Net MD-compatible recorder using the pro­vided software "BeatJam".

! This product features up to 50 times

high speed transfer from PC to MD in
LP4 mode

"

Transfer speed varies by the recording mode. In SP
mode, the speed is less than 1/4 of that in LP4 mode.

"

Time for initialisation and the termination process is
omitted from the calculation of transfer speed.

"

To achieve maximum speed, use the AC adaptor and
a high capacity battery together.

"

Transfer speed depends on the performance of your
PC or the number of tracks to record.

! About ATRAC

The ATRAC (Adaptive TRansform Acoustic Coding) sys­tem 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 com­pressing 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 mon­aural recording. Recordable time varies depending on
the recording mode. If the tracks are recorded on an 80­minute MiniDisc, its recording time changes as follows:

Indication Recording mode Recording

SP Stereo MAX. 80 min.
LP2 2 times long (MDLP

stereo)

LP4 4 times long (MDLP

stereo)

MONO Monaural MAX. 160 min.

time

MAX. 160 min.

MAX. 320 min.

! 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.

Digital audio data can be imported into the hard disk of a
PC in the following methods:

"

Converting the music downloaded via the music distri­bution service on the Internet into ATRAC3 of the
OpenMG system.

"

Recording an audio CD via the CD-ROM drive of a PC
on the hard disk. (Compressing data with the ATRAC3
sound compressing system)

"

Converting the existing MP3, WAV audio files into
ATRAC3 of the OpenMG system.

The saved audio data can be played on the existing MD
player, as its recording method is not changed when
being recorded on an MD. (To play audio data saved in
the MDLP mode, the MDLP-support MD player is
required.)

All the audio data managed by "BeatJam" is encrypted by
the OpenMG system and recorded on the har d disk of
the PC, which preven ts its unauthorised use or distribu­tion.

MiniDisc System Limitations

The unit may have the following symptoms whilst recording or editing. The unit is not out of order.

SYMPTOM LIMITATIONS

"DISC FULL" or "TOC FULL" appears
even though the MiniDisc still has re­cording time left.

The remaining recording time does not
increase even though you erased
tracks.

The total of the recorded time and the
remaining time does not match the max­imum recordable time.

Combine function does not work.

Sound skips in fast reverse/forward.

A track number is created in the middle
of a track.

More than 255 tracks (maximum) cannot be recorded regardless of
the recording time. If the MiniDisc is recorded or edited repeatedly or
if it has scratches (recording skips scratched parts), you may not be
able to record the maximum tracks above.

The unit does not count non-recorded portions that last 12 or fewer
seconds to display the remaining recording time. The time may not
increase even if you erase short tracks.

One cluster (approximately 2 seconds) is the minimum unit for re­cording. For example, a 3-second track uses 2 clusters (approximate­ly 4 seconds). Therefore, the actual recordable time may be shorter
than the displayed time.

A MiniDisc on which recording and editing are repeated may not al­low the combine function.

If one track is divided and recorded in separate places on a repeat­edly recorded or edited MiniDisc, sound may skip.

A track number may be created if there are scratches or dust on the
MiniDisc.
