NEC CD-500E
A single period test report is nearly all that survives of this mid-1980s NEC compact disc player, and it's a useful one, published in HiFI-Stereo (January 1987, p.40).
Overview
The NEC CD-500E is a compact disc player with one documentary source: a test report from Hirsch-Houck Laboratories in the January 1987 issue of HiFI-Stereo (p.40). Without that report there would be nothing to write. It describes a front-loading, three-beam-laser machine built at the height of the first CD boom.
The test report starts with the transport. The CD-500E used a three-beam laser pickup, the tri-beam tracking scheme most first- and second-generation players relied on before single-beam designs took over. Discs loaded through a front-loading motorized drawer, not a top-loading lid, which is the more convenient and more furniture-friendly arrangement. Fast track skip and search were both provided, so you didn't have to wait through a linear scan.
The feature set, as documented in the same HiFI-Stereo test (p.42), was broad for the period. The player had both fixed- and variable-level line outputs. The variable output meant the deck could drive a power amp directly with no preamp in the chain. A four-section OPERATION MODE display reported disc presence, repeat status, and whether a programmed sequence had been stored. There was programmable track memory, and a display of total time. The review also notes that the output could be multiplexed (switched) between the left and right channels, an unusual touch that let a listener check channel balance or isolate one side of a disc.
On the bench, the CD-500E behaved like a competent mid-1980s player. Hirsch-Houck reported that it tracked all of the calibrated defects on the Philips TS5A test disc without difficulty. That was the standard abuse test of the day, and passing it cleanly showed the transport's error correction and servo systems were sorted.
Beyond the January 1987 report, the record thins out. No production years, original list price, or detailed service history have surfaced in the archive's sources. The CD-500E appears in the period press essentially as a reviewed model and little else. The HiFI-Stereo test is the reference document, and the only substantial account of what the machine did.
