Yamaha CD-X1 Natural Sound Vintage Rare CD Compact Disc Player Tested Working
Yamaha’s “second-generation” Compact Disc player, the CD-X1, is than a third the weight, and about half the size of its first-generation predecessor, the CD-1. The styling is very clean and simple, the controls easy to use.
A major contributor to the CD-X1’s size “shrinkage” is the use of two high-density large-scale integrated circuits (LSI’s) designed by Yamaha specifically for this application. Together they replace many of the IC chips and other discrete components used in the CD-1, and they perform many of the most complex functions involved in playing digital discs—including control of disc speed, laser focus, and tracking servos as well as demodulation and error correction of the digital audio data stream. One of the chips also includes a digital filter stage operating at twice the standard sampling frequency, 88.2 kHz instead of 44.1 kHz, which makes it possible to use simpler analog-output low-pass filters to minimize noise, distortion, and high-frequency phase shift.
Besides the new LSI’s, the CD-X1 has a new three-beam laser pickup, and molded plastic parts have replaced many of the heavy, more expensive metal castings or stampings of the first-generation CD players. The unit’s outside dimensions are 13-3/8 x 11-3/8 x 3-5/8 inches, and its weight is just under 8 pounds.
