Features: Upper middle class home MD deck. ATRAC with Type-R DSP, MDLP recording modes, and Scale Factor Edit plus variable coefficient anti-aliasing filter. A new USB based PC-Link kit, the PCLK-MN10 (MSRP: ¥15,000), was announced with this unit for audio transfer (via the deck's digital optical input) and control (editing, titling, playback, etc.) from a PC (audio input from MD to PC is [still] not supported). TOC Cloning possible.

Specs: SNR > 100dB, Dynamic range: > 98dB, THD: <.003%, 24bit delta-sigma ADC, Current pulse DAC.

Improved over MDS-JB640:

  • Extra button on front panel: digital filter (no S.F. edit button, only accessible through menu system)
  • Recording level dial on front panel
  • Extra buttons on 5-column remote control: date recorded, date present, numeric 11-25, music scan, auto space, peak hold, filter, CD player pause, name (name, character, number), play modes (continue, shuffle, program), time.
  • Coaxial input appears on all models, as does 2 optical inputs.
  • Digital filter appears in display modes while stopped, playing and recording. Pitch level appears when stopped and playing.
  • Clock setting, and time/date stamp for recordings.
  • Bit-length switching. Used to improve the digital output quality, by changing the outgoing bit-length.
  • Digital filter changes the tone of the signal going through the analog output.
  • Aluminium front panel, and is also of QS design. This means that the circuitboards inside are on a slant, reducing standing waves (unwanted reverberation), and it gets a nice shiny QS sticker on it.

Anyone got any tips for this one, mine had just started to not eject discs, it tries but they go back in and just read again. Unit plays fine. If I remove the lid I can nudge the disc during the eject process and it will eject. Cant see what I need to tinker with to help the situation.

Sounds like the eject belt - it's an MDM7 series drive and there is a 17mm x 0.8mm belt that can go slack.

Get from Charles Holt cnh_03 on eBay (he had these made for this drive at my suggestion):
