Marantz CM1040 (1997)
The Marantz CM1040 is a CD/MD combination deck from 1997, part of Marantz's "Slim Series" line. It sold in Japan for ¥76,000 and came in two colors, green and titanium black. The CM1040 and the Marantz CM635 appear to be the same unit underneath, with different styling.
The CM1040's main trick was direct digital recording from CD to MD. You put a CD and a recordable MiniDisc in the same machine and dub digitally, with no analog stage in between. A synchronized dubbing function automates the process. The deck has a sampling rate converter that handles 32/44.1/48 kHz inputs, plus optical digital input and output and a coaxial digital input. Both the CD and MD sections use 1-bit D/A conversion, with ATRAC coding on the MD side.
The CD section is specified at 20 Hz-20 kHz ±0.5 dB, with 93 dB dynamic range, 95 dB S/N, and 0.01% THD at 1 kHz. The MD section matches the dynamic range and S/N figures but allows 0.05% THD. The deck has 20-track program/repeat/random play modes, a D-Bus system connection, and a wireless remote. A voice input of 250 mVrms stereo is also on the spec sheet. Power consumption is 12W, and the unit measures 422 × 76 × 309 mm and weighs 4.6 kg.
Period sources describe the CM1040 as "rare and stylish," and it appears to have been a Japan-market model. Most surviving listings are from Japanese auction sites, often paired with the matching Marantz SR1041F amplifier. The record is thin beyond that. No period reviews, production totals, or service history have surfaced in the Archive's files. The CM1040F variant designation appears on some units, and a Russian source lists a CM-1040/2A variant with a 1-bit DAC, but the relationship between these designations is not documented.
