1. Realizes about 8 hours of continuous playback with the included lithium-ion rechargeable battery

  • The power-saving design of the mechanism, pickup, and LSI, as well as the power-saving design of each part, has enabled continuous playback of 8 hours with a single rechargeable battery.
  • We have adopted a high-performance lithium-ion rechargeable battery that does not have a “memory effect” and maintains stable performance even if it is recharged with the remaining battery capacity.
  • The low-voltage design enables playback for about 6 hours with a single high-capacity alkaline AA battery (1.5V). (When using the included AA battery case)
  • By using a lithium-ion rechargeable battery and AA batteries together, it is possible to play continuously for a long time of about 14 hours.
  • Since the main unit is equipped with a DC jack, there is no need to remove the rechargeable battery from the main unit to charge it.

2. Achieved a thin MD jacket size that does not add bulk even when put in a shirt pocket

  • New development of our original core parts has realized a thin type and a size close to that of an MD disc case.
  1. The mechanism is 75% smaller in area than the conventional machine.
  2. The chassis size of the mechanism is also reduced to 75% of the MD cartridge.
  3. Adoption of a thin rectangular lithium-ion rechargeable battery

3. Equipped with a 40-second “skipping guard memory” that is resistant to external vibrations

  • Equipped with a 16-megabit DRAM, which is four times larger than the current one, you can enjoy music comfortably without skipping for up to about 40 seconds even when subjected to intermittent vibrations.

4. Comes with a backlight that makes the display visible even in dark places, and a glowing LCD remote control

  • Adopts a stylish skeleton design that allows you to see through the contents.
  • You can select songs while checking the song name and song number clearly with the remote control even in the car or at night.
  • The headphone section is detachable, so you can connect commercially available large headphones to enjoy even more powerful sound.

5. “MD ⇒ MD edit” output correspondence that can edit voice and text information at the same time

  • In combination with our MD component (MD-X5/X8/X8PC/XL10/XV300), when editing from MD to MD, not only sound but also character information such as disc titles and song titles can be edited at the same time. It supports the output of “MD Edit”.
  • Connect to our components with the separately sold special cable <AD-M5AC>. (The edited sound will be analog.)

6. High-quality sound design that focuses on sound quality

  • The ATRAC (Adaptive TRansform Acoustic Coding) section, which compresses and expands the sound that is the key to MD sound quality, uses the 5th generation 24-bit arithmetic method, allowing you to enjoy clear and extended high-quality sound.
  • Digital X-BASS is used for deep bass reproduction, and you can enjoy powerful deep bass with little noise.

7. Equipped with useful functions unique to discs, such as high-speed song selection, random playback, all-track/single-track repeat, etc.

8. A wide variety of optional accessories are available for use in cars, etc.
