Marantz DD-92
The DD-92's record has a genuine mix-up in it. The spec sheets describe a direct-drive turntable: 33⅓ and 45 rpm, a 30 cm platter weighing 1.0 kg, a static-balance tonearm with 232 mm effective length, and wow-and-flutter rated at 0.015% WRMS. But the period press that survives - Audio (March 1993, p.46) and HiFI-Stereo (April 1993, p.44) - reviewed the DD-92 as a Digital Compact Cassette recorder. That deck could record at sampling frequencies other than 44.1 kHz, and its D/A converters were capable of 18-bit resolution. So there are two entirely different machines sharing a model number. The Archive cannot yet say which is the "real" DD-92, or whether Marantz reused the designation across product lines.
The turntable documentation, corroborated by both Hifi-Wiki and Hifi Engine, points to a competent mid-range direct-drive design. Rumble is rated at -75 dB, tracking error is +1.5°/-0.5°, and stylus pressure range is 0-3 g. Suitable cartridge weight is 4-12 g, with an 8.5 g headshell. Power consumption is 15 W, dimensions are 440 × 165 × 360 mm, and it weighs 8.0 kg. There is one conflict in the record: Hifi-Wiki lists wow-and-flutter as both 0.015% WRMS and 0.045% in different sections of the same page. Hifi Engine corroborates the 0.015% WRMS figure, which is the value used here.
Beyond those specifications, almost nothing is documented. There are no production years, no original price, no bundled cartridge, no service history and no owner reports. If you have a DD-92 turntable - or a DCC recorder bearing the same name - the Archive would like to hear from you.
