Commentary
MD recorder equipped with 20-bit D/A converter and sampling rate converter.
A 20-bit D/A converter is used for the D/A converter.
Equipped with a high-precision sampling converter, it can automatically convert 48kHz/44.1kHz/32kHz to 44.1 khz for digital recording by SCMS method.
In combination with a CS/BS tuner or DAT deck, digital to digital recording such as air check recording of satellite broadcasting or recording from DAT can be performed directly.
(Due to the SCMS method, digital recording between digital audio devices is limited to one generation for copyright protection.)
Equipped with input terminals for one coaxial system and one optical system, and output terminal for one optical system.
With the multi-jog dial, you can enter titles in alphabet / numbers / symbols / katakana.
Built-in editing functions such as move and program move, divide, combine, erase, and all-erase.
It is equipped with a sound-synchronized recording function, and recording starts when the device you want to record plays back.
It supports monaural long-time recording, which is convenient for long-time radio programs and English conversation learning.
