Nakamichi CD Player 4
Little is documented about the Nakamichi CD Player 4. The record shows a single-disc CD player built around a 1-bit DAC with 8x oversampling and a digital filter. It's a conventional single-disc design - no magazine changer here. It has 20-track programming, random and repeat play, and a remote control. There's no CD Text support and no headphone output.
The surviving spec sheet is thin but clean: frequency response rated at 5 Hz–20 kHz ±0.3 dB, signal-to-noise at 105 dB, dynamic range 97 dB, total harmonic distortion 0.003%, and channel separation of 95 dB. Analog output is listed at 2.0 V. It measures 435 × 98 × 326 mm. No weight, no original price, and no production years have surfaced in the available documentation.
Nakamichi's own advertising of the era pushed its higher-end MusicBank multi-disc models. Audio (October 1990, p.3) carried copy touting the CDPlayer2's Bessel-type active analog filtering and "musical accuracy." The CD Player 4 appears to have been the more modest single-disc sibling in that same generation. It shares the house approach to digital filtering but has no multi-disc mechanism. The circuitry and real-world performance are unrecorded in the public record.
