75,000yen(1998 release)

Description
@
micro-disk recorder which carries a variegated edit function.

In order to change both an analog / digital one into a high order accuracy more, a 20-bit D/A& analog-to-digital converter is carried.

The digital input carries two lines, an optical input and a coaxial input.
Moreover, the digital output carries optical 1 system.

The sampling frequency from which Convergence Sublayer/BS tuner, the DAT deck, etc. differ is automatically changed into 44.1kHz which is a sampling frequency of micro disk at the time of an input, and a digital recording is possible.
Moreover, the frequency of 32kHz of the digital input source/44.1 kHz/the 48 kHz is indicated by a main unit by light emitting diode.

As an edit function, Join which connects music, Divide which divides music, Move which moves music, Erase which erases music, All Erase which erases all the music, etc. are possible.
Moreover, intelligences, including a title name, a music name, an artist name, etc., can be inputted in an alphabetical character, a numerical character, and katakana. From a main unit, a jog dial can be scrolled and inputted and it can input direct from remote control.

The compact-disk synchro REC is possible by connecting with the compact disk player of an SANSUI.

The sound recording to micro disk carries the music synchro REC started automatically at the same time sound starts.

An operation of both the compact disk player made from an SANSUI and micro-disk recorder is possible with one remote control.

A maximum of 14 character representations are taken for a front display device, and the level meter and the music calender of 20 music are displayed on others.

Timer Rec in which the sound recording and alarm clock play at the time of going out are possible, and a Timer Play functionality are carried by the interconnection of an external timer.

The monophonic sound recording is supported.

Two kinds of colour variations, gold and black, occur.
