Direct DigitalSync System: Since the D/A converter converts the analog music signal back by changing the pulse density, a particularly exact Clock frequency is required. That's why Sony has integrated the Direct DigitalSync system into the new Pulse D/A converter. A high-precision quartz oscillator is connected directly to this in order to achieve minimum digital jitter and maximum conversion accuracy.
Digital Deemphasis: Some of the CDs on the market are recorded with preemphasis, i.e. with an increase in the highs to improve the signal-to-noise ratio. When playing the record, the heights are then lowered in a mirror image. Conventional systems use analog technology for this and are therefore not 100% accurate. The digital deemphasis function ensures that this process takes place with the required digital precision. So that losses or sound losses do not have to be expected, especially at high frequencies.

New Custom File/Custom Edit: New Custom File consists of a total of 5 programming functions: Program Bank, Disc Memo, Custom Index, Level File and Last Mode Memory. With the Programmbank function, you only need to program the track sequence of your CDs one more time. Because after inserting the CD, the player remembers everything that was once typed to him. For max. 185 CDs, up to 24 selected tracks can be programmed in any order. In addition, you can provide the CD with a 10-digit marking via Disc Memo. For example, with the name of the performer. The identifier is automatically displayed on the display when the CD is inserted. In addition, you have the option of using the Custom Index 10 function to program any starting points where your favorite passages begin. These can be called up directly with the program keys 1-10. A practical device, especially for CDs with longer classical pieces of music. With the level file function you have the possibility to save a special volume for each CD. During playback, the CD player then automatically sets the programmed value. And with Last Mode Memory, all operating states, such as repeat, fade time, auto space, etc., are stored. After inserting the respective CD, they can be retrieved and made available as desired. And if your tastes change over time – no problem. You can make changes and deletions for each CD, for each track individually. The Time Edit custom edit function makes it even easier to transfer to cassette. You simply enter the runtime of the cassette and press the Edit button. The titles of the CD are then selected so that they fit completely on a cassette. In addition, Time Edit offers 4 fixed programmed runtimes in addition to manual input: 46/54/60 and 90 minutes. The Priority Time Edit function allows you to select pieces that should be played over as a priority. And the Program Edit function allows you to compile programs manually and read the entire program time directly.

Just Edit/Link Edit: Just Edit works like Time Edit, but the track compilation is optimized to the time specification, without observing the track order. If the Time or Just Edit functions cannot completely fill a cassette page due to too few tracks, additional tracks, even from another CD, can be attached with Link Edit. Link automatically offers the titles that optimally fill the remaining time.

Variable Digital Fader: The Digital Fader consists of 3 subfunctions: the Manual Fader, the Time Fader and the Variable Fade. With the Manual Fader you can get off "softly" at any point of a running track of the CD. After pressing the fader button, the CD player lowers within 5 sec. the volume is continuously down to zero. After that, he goes to the pause function to wait for new instructions. For example, to fade back into the interrupted piece. In this way, it ensures optimal utilization of the tape material when transferring to cassette. With the Time Fader, you also have the option of programming the fading process to the exact second. You use the full length of the cassette without being surprised by sudden silence while listening. The variable fade function allows you to change the fade-in or fade-out time between 2 and 10 seconds in 1-second sections. This gives you the opportunity to implement particularly long or very short fade-out or fade-in processes.
