The DAD-001 was a pioneer of separate CD players, and was an impressive machine with excellent sound quality. This was possibly the world's first, separate CD player, Lo-D DAP-001/HDA-001. The processor HDA-001 was equipped with a 16-bit linear DA converter with independent left and right channels. The independent left and right 16-bit linear DA converter Prevents distortion that occurs when switching between positive and negative signals, which is equivalent to "switching distortion" in amplifiers. The laser pickup uses a two-axis orthogonal optical system that eliminates the effects of laser light reflection by a reflecting prism and further enhances tracking capabilities. In addition, tracking errors caused by disc eccentricity are handled by a three-spot method that detects errors by the difference in the amount of reflected light from three spots. It also contains the industry's first 5-fold correction signal LSI-equipped laser.
