Commentary
MD recorder equipped with digital technology such as 20-bit D/A converter, ATRAC Ver4.5, sampling rate converter, etc.
High-efficiency coding technology (audio compression technology) ATRAC uses ATRAC Ver4.5, which performs 24-bit arithmetic processing.
Compared to the conventional type, the reproducibility of micro-level music is improved, and the dynamic range is greatly expanded.
A 20-bit D/A converter is used for D/A conversion.
In addition, it is equipped with a sampling rate converter in order to support recording of sources with sampling frequencies of 32 kHz and 48 kHz. All sampling frequencies are converted to 44.1 kHz, which is the sampling frequency of MD, and digital recording is possible by SCMS method.
Equipped with a multi-jog dial, you can enter artist names and song names easily with the multi-jog dial.
It is equipped with a sound-synchronized recording function and starts recording when the device you want to record plays back.
It is also equipped with convenient functions for recording, such as Auto Cut, which automatically stops recording when no sound is input during Sound Synchro Sound operation, Rec Auto Pause, which creates an unrecorded part and enters a pause state, and Auto Space, which keeps the distance between songs on a CD constant.
It is equipped with editing functions such as Move which allows you to move your favorite songs to your favorite places, Quick Move function which allows you to rearrange recorded songs in your favorite order, Divide which divides one song, Combine which combines two songs, Erase which erases only specified songs, Erase all songs, etc.
It is equipped with a monaural long-time recording function which is convenient for recording long-time radio programs and English conversation learning.
Wireless remote control is included.
