NEC CD-830DS (ca. 1989)
Surviving information on the NEC CD-830DS is thin - essentially one thorough laboratory test report. Stereo Review (May 1989, p.37) ran Julian Hirsch's Hirsch-Houck Labs equipment test of the CD-830DS, beginning on page 35. That review is nearly the whole record.
The CD-830DS was a compact disc player. Its standout feature was Auto Edit, which selected tracks on a disc to fit the recording time of a tape cassette. It could even prepare both sides of the cassette in a single operation, all from a single button press. A time button stepped sequentially through the disc, and the display showed the status of various control functions.
Stereo Review (May 1989, p.38) reported noise between -120 and -130 dB, with the largest component a 120-Hz power-supply hum at -100 dB. THD plus noise at the 0-dB level measured between -93 and -95 dB. The player was 17 inches wide, 12 inches deep, and 4⅜ inches high. It was also run through the severe error-correction and tracking tests of the Pierre Verany test disc #2, though the surviving copy of the report cuts off before that section's conclusion.
