|IN: line, optical, coax. OUT: line x 2, optical, (D7 may have coax out, but D707 definitely does not have coax out).||420 x 105 x 294mm, 3.9kg|
Features: Uses a Pioneer developed ATRAC, which they call "ASRAC" (apparently improves bit allocation by considering the bit requirements of all 3 frequency bands). 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.
Specs: freq resp.: 8-20kHz, SNR: 101dB (D7), 100dB (D707), Dyn. range: 94dB, THD: .005%

|In: line, mic, optical coax. Out: optical, line, hdphn.||Orig: 270 x 124 x 335mm 3.0Kg, MKII: 270 x 93 x 311mm, 3.1Kg|
Features: Sampling rate converter. Synchro recording (start recording when audio appears at input). Title search. Built in wall clock based timer for recording and playback.
Variants: Smaller (93mm wide) Sharp MD-R1MKII supercedes original unit. Upgrade apparently includes 24-bit ATRAC (and 20-bit wide processing LSI?)
Criticism: Sampling rate conversion is a very convenient feature. It will be a must for MD decks before long. But be careful to check the performance. I found the specs of Sharp's sampling rate converter in IEEE trans. on consumer electronics. They are .. S/N 90dB, Distortion 0.005% (1kHz) That's about 14-bit accuracy. I've not yet checked the sound quality myself, but I'm afraid that it will affect the sound quality of low level music [when sampling rate conversion is used]. -Takeshi SASAKI
