NEC CD-607E (1985)
The NEC CD-607E is a compact disc player from the mid-1980s. Today it survives mainly in one period test report, in High Fidelity (September 1985, p.44), and that report gives us nearly everything concretely known about the machine.
NEC was among the first manufacturers to use oversampling at 88.2 kHz, and the CD-607E put the approach to work in a full-featured player. High Fidelity measured channel separation above 70 dB across the frequency range, far more than needed for good stereo imaging. The review also documents a 1 kHz square-wave response test. The player came with an infrared remote control that duplicated the front-panel functions, including a programmable memory for track sequences. Two display readouts handled remaining time: one for the current track, one for the total unplayed portion of the disc or programmed sequence.
The front panel measured 17 by 4 inches, with a chassis depth of 13 inches plus clearance. Beyond the September 1985 review, documentation is sparse. No production years, original price, or detailed service history have surfaced in the archive.
Known details from the period review:
- Channel separation: greater than 70 dB throughout the frequency range
- Oversampling at 88.2 kHz (NEC among the first to adopt it)
- Infrared remote control with full function duplication
- Programmable track memory with "remaining time" and "total remaining time" displays
- Front dimensions: 17 × 4 inches; 13 inches deep plus clearance
