KENWOOD DM-7090

Commentary

This MD recorder was released as an improved version of the DM 7080.

The DM-7090 is equipped with a 20-bit REC D. R. I. V. E., which is an improved version of the D. R. I. V. E. system so that it can be used for recording.
This makes it possible to enjoy both recording and playback at 20-bit resolution, and analog sources can also be recorded and played at 20-bit resolution.

It is equipped with a sampling rate converter for recording and playback of digital sources other than CDs such as BS, CS, and DAT. The DM-7090 can automatically convert a j-value source at 44.1/32/48kHz to 44.1 kHz for digital recording using the SCSM method.

The A/D converter is equipped with a high-quality A to D converter with 1-bit 5th-noise shaping and 18-bit resolution.

It is equipped with new ATRAC. In this method, compared with the conventional ATRAC, the bit floating improves the calculation capability at the minute input, and the bit allocation algorithm at the time of compression is also revised.

Equipped with a quick erase function, you can divide and erase the part you want to delete simply by specifying the capacity of repeat A-B.
It is also equipped with functions such as Quick Move and Track Move for changing the order of songs one by one, Track Divide for dividing songs, Track Combine for connecting songs, and Erase.

It is equipped with an edit cancel function to restore the disc to its original state when editing by mistake.

It is equipped with a title search that can be played while checking the title of the music.

Equipped with a multi-jog dial for easy title input and track skip.

Equipped with 3-mode level meter.

The display uses a large 12-character dot FL tube.

Katakana characters are supported.

It has a preview function that allows you to fine-tune editing.

Supports monaural long-time recording.

A remote control is included.
