Commentary

A CD player with a 2 dac / 18 bit conversion system.

The D/A AC-18bit conversion system is used for the D/A converter.
In this circuit, a D/A converter is mounted on each Lch/Rch, and the data sent to each D/A converter is controlled by an 18-bit processor LSI to obtain a high resolution of 18 bits. Together with the high resolution of the 18-bit 4-times oversampling digital filter, the reproducibility of small signals is greatly improved.

A unique classAA method has been adopted for the output buffer amplifier of the audio circuit to realize stable waveform transmission without adverse effect of connection load.
In addition, a separate digital / analog power supply circuit is used for the power supply circuit to prevent adverse effects from the digital circuit to the analog circuit.

The optical deck is based on the BMC mechanism, which has heat resistance of 200 ℃ and excellent vibration damping characteristics, in order to suppress the adverse effect of external vibration. By floating this deck, high vibration damping effect is obtained.
In addition, a high-speed linear access system using a linear motor is adopted for the drive part of the traverse mechanism that moves the pickup, and high-speed access is realized by a unique control system using a microcomputer, and high durability and quietness are obtained.

Equipped with an edit guide function, you can automatically calculate the number of songs that can be recorded on the A side and B side of the tape, the number of songs, and the recording time by selecting the recording time (90 minutes, 60 minutes, 46 minutes) of the tape and display it on the display.
You can also program a song by specifying any recording time and checking the remaining time on the tape.

It is equipped with an auto-peak search function that automatically detects the peak level of all songs on the disc and programs, and then repeats the music for ± 3 seconds before and after the peak point. This function enables you to easily set the optimum recording level on the deck side.

It is equipped with a large FL multi-display which can display music matrix display and 4-mode time.

Equipped with coaxial digital output terminal.

It is equipped with functions such as repeat / A-B repeat, random play, music scan to play only the intro part of a song 15 seconds at a time, 2-speed manual search, skip and index search.

Equipped with a power-on timer, if a disc is inserted when the power is turned on, playback will start automatically.

Equipped with headphone port equipped with variable volume.

27-key full remote control is included.
