| 1. |
The first in the world.
- Portable MD
recorder equipped with 1 'Mobility one bit
digital amplifier' |
|
| ･ |
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. [It] installed it in portable MD
recorder for the first time. |
| ･ |
Higher-order- An extremely a tone quality
deteriorated little, natural, clear tone quality is
achieved by inputting one bit digital voice 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 resolution of the sound is rapidly improved, and
the sound that "Resolution of the sound" by which the
speed and the smoothness of standing up of the sound are
reproduced in the high quality is high can be achieved,
and the high pitched sound quality sound be reproduced.
| |
| 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 (hope
retail price 3,300 yen) of "Four pole plug" type were
prepared as another goods for sale.
| ※ |
"Three pole plug" To enjoy it because a high
pitched sound quality "Mobility one bit digital
amplifier" original is demonstrated enough though
the use of the headphone of the type is also
possible, I will recommend use with the headphone
of "Four pole plug" type.
| | |
| 3. |
The longest in the world in portable MD
recorder. - About
one 120 during the
hour- For the reproduction and about 64 hours of a long
time of two- The
recording of two 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 <録(unknown
word)> 第(unknown word) <again> the tenth
generation LSI of the low consumption electric power
<-> type by which the Σ modulation circuit was
made one package. |
| ･ |
In using of the nickel hydrogen charge pond and one
high capacity AA alkali dry battery, together, longests
in the world. - One can
be recorded for long time of the reproduction and about
64 hours of a long time of about 120 hours. Moreover,
the recording of about 71 hours and reproduction/about
38 hours was achieved in the recording of about 42 hours
and reproduction/about 22 hours and the high capacity
alkali dry batteries of one (1.5V) on one charge pond
(Both at the LP4 mode).
| |
| 4. |
"MDLP group mode" adoption which is
recorded and can reproduced according to
group |
|
| ･ |
When recording, the group of each album and each
artist, etc. can be set in one mini-disc. Setting of the
group is possible up to 99 groups or less. If the group
is chosen and the tune which wants to be heard is
selected, a target tune can be speedily reproduced. The
feature of MDLP which four times or less a mini-disc can
be collected for a long time can be conveniently
enjoyed. |
| ･ |
In addition, various group edit functions that it
was able to be had to use it conveniently were adopted.
| (1) |
"Group change" where tune can be moved to
other groups |
| (2) |
"Group top move" where group which specifies
it can be moved to the first group of MD |
| (3) |
"(*guruupuireis*)" by which tune in group can
be collectively deleted |
| (4) |
"Group booking" which can make group
beforehand, and record to group later |
| (5) |
"Group arrangement" which moves tune by which
group is not set at the end of MD, and can hear it
with same 曲順(unknown word) even in equipment not
to be able to do group
reproduction | | |
| 5. |
An easy, convenient microphone recording
function is installed. |
|
'Trace backing recording'- It is possible even by
an analog connection.
| ･ |
When the microphone recording stops temporarily, the
recorded sound source is memory します(unknown word)
temporarily . in the main body if [it] sets it by the
menu beforehand. Because the memory されていた(unknown
word) sound source is recorded though the timing of the
recording start is delayed, the 録り(unknown word) delay
is prevented (It is possible to set it in either of five
seconds/ten seconds/30 seconds).
| 'Group improvement recording'
| ･ |
A new group can be easily made while recording the
microphone. For instance, because it is possible to
reproduce from the head of the subject for discussion if
a new group is made only by pushing the GROUP key when
the subject for discussion changes when the conference
is recorded, and the group reproduces, the part which
wants to search can be easily discovered.
| 'Microphone synchronized
function'
| ･ |
The recording starts automatically reacting on the
sound and the voice. Moreover, the disk can be used
without uselessness because a no sound of three seconds
or more is perceived and [it] stops temporarily.
| 'Twice recording function of
monaural length time'
| ･ |
It is possible to record by the twice at the disk
display time in the monaural mode.
| 'Auto mark function of time'
| ･ |
The point when the head putting out point can be
automatically recorded at constant intervals (3/10 step
of three minute/five minute/change), and [it] asks it
again later is easily searchable.
| |
| 6. |
Only the tune of the favorite is
installed and "Favorite reproduction" function that
registration & can be reproduced is installed.
|
|
| ･ |
Tunes of the favorite of each disk were specified up
to ten, and "Favorite reproduction" function that the
reproduction only of the tune was able to be enjoyed
anytime was installed. It is possible to specify easily
while reproducing the tune, and disks up to nine can be
registered as "Favorite disk". An automatic reproduction
of a favorite tune can be started only by inserting the
disk. | |
| 7. |
Abundant reproduction functions such as
convenient "Reproduction speed control" for the MDLP
reproduction are installed. |
|
| ･ |
"Reproduction speed control" function which can be
enjoyed at the reproduction speed of the favor is
installed. The reproduction speed is changeable in
-30%/-20%/-10%/+5%/+15% and [it] comes. The part not
caught easily by the microphone recording etc. can be
caught easily and [it] reproduce. |
| ･ |
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
convenient reproduction function random to reproduce,
random to repeat, all tunes to reproduce the repetition
one can be had to be enjoyed.
| |
| 8. |
*** Attachment <"Charge stand" which
can be charged easily in portable telephone
sense> |
|
| ･ |
*** It was easily attached <the charge stand
which was able to be charged> only by putting the
main body in the portable telephone sense.
| |
| 9. |
"Digital recording level control" is
installed. |
|
| ･ |
*** [It] tends <a recording level of CD different
respectively, and BS voice broadcasting and digital
communication satellite broadcasting, etc.>
<smaller than CD the recording level>. The disk
where the recording level becomes complete can be
edited, and when reproducing, music can be enjoyed by
the same volume if the recording level is adjusted when
such a digital sound source is recorded.
| |
| 10. |
"Heavy bass & high pitched sound
control" by which [it] sticks to the quality of the sound is
adopted. |
|
| ･ |
The high pitched sound quality clearly and with the
expansion can be enjoyed by adopting 24 bit operation
method and three dimension (axis direction/frequency
axis direction/time direction of the amplitude)
adjustment type (*bittoarokeishon'arugorizum*) in the
part ATRAC where [it] compresses/the sound which becomes
the nucleus of the tone quality of MD is extended.
|
| ･ |
Because X-BASS of a digital method is adopted in the
heavy bass reproduction, and only digital adjusts a
heavy bass with power by three stages, it is possible to
enjoy it. |
| ･ |
The “TREBLE" adjustment function of a digital
method that the high pitched sound part can be adjusted
to the interval of the favor is adopted at the same time
as a heavy bass's reproducing. It is possible to change
to upper and lower each of two stages.
| |
| 11. |
A convenient alarm function is installed.
|
|
| ･ |
The music under the reproduction will be (*myuut*)ed
if becoming set time, and I inform because of the alarm
sound. It is convenient for the riding past prevention
of the train etc.Setting after 99 minutes from one
minute is possible every minute.
| |
| 12. |
*** It is <liquid crystal remote
control of easy convenient &> attached by a slim
design. |
|
| ･ |
It is possible to operate it easily a slim 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.
| |
| 13. |
Portable MD recorder of portable compact
size |
|
| ･ |
A compact size of 78.9mm in width ×17.8mm in height
×71.9mm in the depth and about 140g(The charge pond
contains it) in mass was achieved by consolidating a
reduction in the number of parts and main parts.
| |
| 14. |
"Character stamp" function that character
information from MD to MD can be easily
edited |
|
| ･ |
After [it] records, the stamp of the sound of
character information on mastering MD can be wholly done
from MD to MD when editing it.
| |
| 15. |
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.
| |
| 16. |
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.
| |
| 17. |
"CD sound synchronized recording" of
digital/analog correspondence |
|
| ･ |
When recording from CD, an analog connection in
addition to a digital connection does the synchronized
to the sound of CD and starts the recording of MD.
Moreover, if the state of a no sound of three seconds or
more continues, [it] stops temporarily.
