Feature > of < MD-DS8

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 ƒ° 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 ‚«(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 ƒ° 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 "‰¹”ò‚Ñ(unknown word) guard memory" of about maximum 160 second (LP4 o'clock)
¥ Music can be pleasantly enjoyed without doing sound ”ò‚Ñ for about the maximum 160 seconds at the LP4 mode even if intermitted vibration is received by installing of 16 Mbits DRAM.

¦1 As of September 2, 2002
¦2 [It] develops jointly with the Lake technology company, and a virtual system (Dolby, a Dolby NR, and a double D sign are trademarks of (*dorubiiraboratoriiz*)) for the headphone with built-in LSI which the (*dorubiiraboratoriiz*) Co. recognized.
¦3 The continuous reproduction time (At the LP4 mode) when the attached charge pond is used together with the high capacity AA alkali dry battery.
