MJ-D707 appears to be an export version, while MJ-D7 is the domestic version.

Uses a Pioneer developed ATRAC, which they call "ASRAC".

Pioneer ASRAC is in use only for analog signal record, it's an analog processed pre-equuilizing correction before passing the audio signal to standard Sharp 5 Atrac encoder. Digital recording uses pure standard Sharp 5 Atrac

Incorporates Pioneer's "Digital Noise Reduction" (already available on some Pioneer cassette decks) and "Legato Link Conversion" (which synthetically produces frequencies up to 40kHz). Digital recording level control (-48dB to +12dB). Time skip function allows quick movement through audio material at 30s or 60s per click. Medley playback function fades across track changes. Name clip function allows track titles to be duplicated and edited. Synchro start recording. Name clip (copy and paste?) function.
