Mitsubishi CD-500
Little is documented about the Mitsubishi CD-500. The one substantial surviving record is a February 1998 buying-guide listing in HI-Fi-Stereo-Buyers (p.58), where the model appears as the M-CD500, a five-disc carousel CD changer in black. That listing is essentially the whole archive on this model, so here is what it says.
The changer uses a 1-bit D/A converter with 8× oversampling, an 18-bit digital filter and a 3-pole analog filter. Listed features are skip and search, random and repeat play, track, remaining-time and total-time displays, and remote control with system compatibility. The listing also notes that four discs can be changed, but the OCR cuts the sentence off there. Published figures: THD 0.006% at 1 kHz, S/N 96 dBA, dynamic range 90 dB, and channel separation 90 dB at 1 kHz. Price in the guide was $180.
Production years, design context and any formal review coverage are unrecorded in the sources found. The CD-500 / M-CD500 name difference comes straight from the guide. As far as the Archive is concerned it is the same machine, but the record is too thin to be certain about its history.
