Commentary
A CD player with a variety of performance time editing functions.
It is equipped with an auto-edit function that automatically creates a program within the range of time specified at the beginning and plays the first song on the disc or the specified song in order. In addition, the manual edit function allows you to program freely within the specified range of time while checking the remaining time.
Equipped with an auto fade out function using the fade out key.
You can automatically set a gap of at least 4 seconds between songs to be played.
It is equipped with a function to display the number of songs that can be played within the remaining time of the tape by flashing in accordance with the remaining time.
In order to eliminate digital noise, digital and analog circuits are connected by optical transmission method.
Optical transmission systems are used Route 6 for L/R serial data, latch pulse signals, clock signals, control signals, etc.
A 16-bit oversampling digital filter reduces the load on the analog filter by increasing the distance between the music signal and the sampling noise.
In order to prevent digital noise from entering the analog section via the power supply circuit, it is separated from the power transformer winding and interference between digital and analog is eliminated.
Equipped with a digital output terminal.
In order to release the optical pickup system from the influence of vibration, an anti-vibration design optical chassis is adopted, and NEC's original floating suspension absorbs external vibration and internal vibration caused by motor rotation.
Equipped with 3 types of repeat function, index search, introscan, 24-track random program memory, 2-speed music search, and skip selection function.
Equipped with a headphone port with volume.
Equipped with a power on start function that can be played by timer start.
Equipped with two analog output terminals, variable and fixed.
Wireless remote controller with 10 keys is included.
