Commentary
A CD player developed with high sound quality and non-resonance technology similar to the high-end model.
In order to improve the phase difference of the photodetector that occurs when optical signals are converted into electrical signals and to generate high-precision RF signals, we have adopted an Accu-focus system.
A digital filter is used in the digital circuit to obtain low-distortion audio characteristics without a low-pass filter.
Uses a magnet clamp type disk stabilizer that fixes the disk by the attraction force of the magnet.
Because the disk vibration is non-contact, it is not directly transmitted to the pickup or other circuits, enabling stable signal reading.
It adopts a floating structure in which the optical system mechanism is lifted from the chassis, so that resonance is completely eliminated.
In addition, the ballast base that lowers the center of gravity of the mechanical chassis rather than the mechanism support part realizes stable signal reading.
Uses a honeycomb chassis with honeycomb ribs on the chassis bottom plate.
Equipped with an auto program edit function convenient for tape editing.
It uses a pause program function that allows you to insert a pause during the program of a song.
Equipped with a power on start function that enables timer start.
