Marantz DV4000 (1999)
The Marantz DV4000 (also written DV-4000 in some sources) was a DVD player released in 1999 at ¥85,000. It belonged to Marantz's C-series line. It was positioned as a player that brought the company's audio engineering into the then-new DVD format. The front panel used the scratch hairline finish aluminum treatment Marantz favored at the time.
The DV4000 played DVD (8/12cm), Video CD, CD-DA, and CD-R. The video section used a 27MHz/10-bit D/A converter. The audio side ran a 96kHz/24-bit converter. Video output included composite, S-video, and component (color difference) jacks. Digital audio came out through both optical and coaxial outputs. On the audio side, Marantz fitted its proprietary HDAM modules, the high-speed voltage amplifier modules used in its higher-end gear. It also separated the digital switching supply from the audio linear regulator to keep noise out of the analog stage. A digital filter switching function let you choose between sharp and soft roll-off characteristics. A Virtual Dolby Digital mode simulated 5.1-channel surround through two speakers.
Rated specs: signal-to-noise ratio and dynamic range both 100dB (EIAJ), total harmonic distortion 0.0025% (EIAJ). Frequency response ran 4Hz - 22kHz on 48kHz-sampled DVD, extending to 44kHz on 96kHz-sampled discs, and 4Hz - 20kHz on CD-DA/Video CD. The unit drew 19W and measured 440 × 88 × 333mm at 3.3kg. A wireless remote was included.
Picture adjustments covered sharpness, brightness, color, and contrast. A zoom function offered 2x or 4x magnification during playback. An auto power-off could drop the unit into standby after roughly 30 minutes stopped in the screen-saver state. A 56-page service manual exists and circulates among collectors, covering the DV4000/F1N/K1G/N1B/S1G/U1B variants.
