| 1. |
The first in the world.
- Portable MD
player who installs 'Mobility one bit digital amplifier
1' |
|
| ･ |
The technology of "One bit digital amplifier" to
have already installed in home audio and to get the
favorable comment is newly developed and 'Mobility one
bit digital amplifier'applied for a mobile equipment is
developed newly. Equipped with the first time in
portable MD player- One
was done. |
| ･ |
*** <"> higher-orderAn extremely a tone
quality deteriorated little, natural, clear tone quality
is achieved by inputting one bit digital signal from -
the Σ modulation circuit" directly to the fixed voltage
switching circuit, and doing transmission/the
amplification processing in the amplifier as it is.
|
| ･ |
The full bridge method with independent output steps
in each voice signal of radical き(unknown word) and +-
is adopted for the same high pitched sound quality
design thought as one bit amplifier for pure audio. The
distortion and the noise element generated by the factor
of the voltage change etc. cancel each other, and a
faithful music reproduction to the field or more sound
becomes possible. *** It is past portable audio and a
low warp rate which was to have done in the half bridge
method (<-> signal the side of a right and left
channel is shared) which has been adopted.; The sound
that clearly and the plain degree is good is achieved
according to the low noise characteristic.;
| |
| 2. |
"Four pole (*puraguheddohon*)" by which
the high pitched sound quality of 'Mobility one bit digital
amplifier'is made the best use of is adopted.
|
|
| ･ |
The headphone which was the final steps of the sound
and remote controls also stuck to the high pitched sound
quality making, and an inner headphone of "Four pole
plug" type by which a right and left sound was complete
and independent separated and remote control were
adopted. The high pitched sound quality reproduction by
which the performance of 'Mobility one bit digital
amplifier'is made the best use of can be enjoyed. |
| ･ |
The open air type stereo headphone and HP-MD1 (sale
schedule at the end of September) of "Four pole plug"
type were prepared as another goods for sale.
|  |
| 3. |
"Dolby NR headphone system" to be able to
enjoy presence to which [it] listens with
speaker- Two is
installed. |
|
| ･ |
The characteristic of the distance etc. of both ears
by the size of the reflection of the sound from not only
the area of the room but also characteristics such as
floors and walls and men' earlobes and the shoulders and
the head was simulated and developed "Dolby NR headphone
system" was installed.
The presence to which [it]
listens with < speaker is headphone and achievement
>.
The presence to which [it] listens with the
speaker by decreasing 'Sound it in the head'sense which
feels when the headphone is used can be achieved, and a
natural, pleasant sound be enjoyed.
The music
reproduction is (*pittari*) of the mini-disc recorded in
the MDLP mode for a long time.
> which can choose
sound of < three types
The sound scene
reproduction which suits one's taste can be enjoyed from
three kinds of modes (STUDIO/LIVE/DOME) with a different
combination of the size and the effect of the echo of
the room.
| STUDIO |
: |
Setting of small room. [It] gives in all music
and a standard effect is given to the reproduction
of the movie voice. |
| LIVE |
: |
Setting of room of the same size as STUDIO.
[It] echoes more slightly than STUDIO, and the
effect is given to the reproduction of music
especially.
|
| DOME |
: |
Setting of larger room than STUDIO. The effect
is given to the concert music and the movie voice
in a wide hall.
| | |
| 4. |
For about 180 hours by the conserve
electric power design only of a digital
amplifier- The reproduction of three for a long time
is achieved. |
|
| ･ |
It is higher-order with LSI of ATRAC which can be
called the heart of MD. - The reproduction was achieved
for a long time by adopting the seventh reproduction
generation of low consumption electric power type by
which the Σ modulation circuit was made one package LSI.
|
| ･ |
It is possible to reproduce for long time of about
180 hours by using together about the nickel hydrogen
charge pond and 1 high capacity AA alkali dry battery.
Moreover, the reproduction of about 101 hours was
achieved for about 62 hours in one high capacity AA
alkali dry battery on one charge pond (Setting both LP4
mode/Dolby NR headphone system at NORMAL).
| |
| 5. |
*** Attachment <"Charge stand" which
can be charged easily in portable telephone sense>
| ･ |
*** It is easily attached <the charge stand which
can be charged> only by putting the main body in the
portable telephone sense.
| |
| 6. |
Portable MD player of portable compact
size |
|
| ･ |
A compact size of 71.2mm in width ×12.0mm in height
×77.9mm in the depth and about 97g(charge pond
inclusion) in mass was achieved by consolidating a
reduction in the number of parts and main parts.
| |
| 7. |
"MDLP Nabis" adoption where LED shines
according to kind of recording mode |
|
| ･ |
*** The tune under the reproduction : in one glance
<which recording mode> in a blinking blue LED
frequency in the upper part of the main body.; *** It is
possible to confirm it (<tune of "Continuousness of
blinking twice" and the LP4 mode> <"Four time
continuousness of blinking"> blink in the tune of
"Continuousness of blinking once" and the LP2 mode in
the tune recorded in the SP/monaural length time mode).;
Moreover, blue LED blinks by various patterns according
to the charge and the content of the operation, and the
operation situation is produced fashionable.
| |
| 8. |
"MDLP group mode" which each group can
reproduce from one mini-disc |
|
| ･ |
Each group can be quickly reproduced by selecting
the group of the favor from the mini-disc recorded by
"MDLP group mode". (The disk to which the group was set
is used) | |
| 9. |
A slim NEW design is adopted. *** Easy
convenient & <liquid crystal remote control>
attachment |
|
| ･ |
It is possible to operate it easily a slim NEW
design is adopted, and it is easy to grasping. |
| ･ |
The key only for convenient GROUP for the group
reproduction is adopted. Setting the group reproduction
and the group which wants to reproduce can easily select
it. |
| ･ |
The display can be easily confirmed because the
backing light addition even by a dark point.
| |
| 10. |
Heavy bass reproduction by which [it]
sticks to quality of sound |
|
| ･ |
X-BASS of a digital method can be adopted in the
heavy bass reproduction, only digital be enjoyed, and a
heavy bass with power be enjoyed.
| |
| 11. |
Abundant reproduction functions such as
convenient "Introduction reproduction" for the MDLP
reproduction are installed. |
|
| ･ |
The tune of the favor can be quickly retrieved from
the disk recorded for a long time in the LP mode by
"Introduction reproduction" function to reproduce each
tune automatically by about nine seconds. Moreover, a
variegated, convenient reproduction random to reproduce,
random to repeat, all tunes to reproduce the repetition
one can be had to be enjoyed.
| |
| 12. |
The (*wantatchiijekt*) mechanism with an
easy disk change is installed. |
|
| ･ |
Because the lid opens and the disk comes out
automatically if the opening button is done in the
slide, the disk change can be smoothly done.
| |
| 13. |
Strength in vibration from the outside,
and "音飛び(unknown word) guard memory" of about maximum 160
second (LP4 o'clock) |
|
| ･ |
Music can be pleasantly enjoyed without doing sound
飛び for about the maximum 160 seconds at the LP4 mode
even if intermitted vibration is received by installing
of 16 Mbits DRAM.
