Commentary
CD player with functions such as 32 sets random program.
High-performance optical deck is adopted for the mechanism part.
By taking advantage of our in-house development capabilities in semiconductor lasers, we have simplified the laser path and installed a laser pickup with a new support system for the objective lens actuator. In addition, two newly developed ICs are used in the servo circuit to perform precise focus and tracking servo along with the 3-beam astigmatic system.
The D/A converter uses a 16-bit D/A converter developed in-house.
The high-precision thin-film resistance element that serves as a reference resistance is further subjected to ultra-precision trimming with a laser beam, and by thoroughly pursuing the element, we have obtained a high accuracy of ± 0.002% or less for non-linear strain.
An 11th-order low-pass filter is used to cut unwanted high-frequency digital components (aliasing noise and sampling frequency) contained in the audio signal just output from the D/A converter.
Features include 32-step random access memory, 10-key direct access, music scan, search, index scan, auto pause, auto repeat, and more.
Equipped with FL display of bar graph and digital display.
Equipped with a level variable headphone port, timer play switch, synchronized recording port and accessory port.
There are 2 variations, black and silver.
