Compact Disc Player CD1

Cambridge Audio, CD1 Compact Disc player designed by Stan Curtis was the most elaborate and expensive player in the U.K. when introduced in 1985.

Great care was taken over the mechanical construction of the CD transport mechanism which was mounted on a lead beam suspension to reduce disc reading errors.

The CD1 also uses the ubiquitous Philips four-times oversampling system. The unit has a multiple conversion system, using three, 14 -bit D/A converters per channel in a "voting" arrangement, if one disagrees with the other two, its output is ignored. The filtering system uses three, linear-phase, shunt feedback filters. Switches allow selection of any filter or pair of filters, six choices in all, tailoring the sound to match the different filters used in recording various CDs. A volume control permits direct connection to a power amplifier, and there are serial and direct digital outputs.

It was also the first player to be split into two separate boxes, the upper half was where the disc tray and power supply were located. The bottom half housed the DAC.

Magazine reviews were outstanding, and the company found itself in the enviable position of being back ordered by six months even before the first unit was delivered.
