Commentary
A CD player with full-fledged specifications for sound quality and a variety of editing functions.
It is equipped with an auto-edit function that automatically programs how many songs can be recorded within a specified time and an auto-space function that automatically sets a space of at least 4 seconds between songs.
It uses a 16-bit digital filter and uses oversampling to expand the interval between the music signal and the sampling noise to reduce the load on the analog filter.
The pickup section has been reduced in size and weight, and parts susceptible to vibration have been floated to eliminate unnecessary vibration.
In addition to the main laser light for reading signals, a 3-beam laser pickup with two sub-laser lights for detection shifted to the left and right is used for the pickup part, which detects tracking errors and prevents errors by servo.
It is equipped with introscan and 24 songs random program memory function.
Wireless remote controller with 10 keys is included.
