Equipped with multi-memory, this 6-string magazine type CD player enables smart & easy operation.

You can play 6 CDs continuously without choose your favorite songs from 6 CDs just by putting in the 6 CDs performance magazine (can store up to 6 CDs) without changing the disc.

Equipped with a large capacity multi-memory, it realizes smart & easy operation.
First, when you insert the magazine into the main body, it reads the data called TOC (Table of Contents) of 6 CDs. Then, it memorizes the program play (or delete) and attenuator levels. If you insert the magazine again, you can play with the same information as before regardless of whether the power is turned on or off.
Up to 20 magazines can be stored.

An 8 fs digital filter enables the use of a low-order low-pass filter and achieves hand-distortion characteristics with little phase rotation.
In addition, a real 18-bit left / right independent twin linear envelope D/A converter has been adopted to reduce the error generated at the MSB switching part by the linear envelope method and to measure low distortion factor.
In addition, a class A FET buffer is adopted at the final stage of the low-pass filter to reduce the load of the OP amplifier and to constitute a low-pass filter with low distortion factor.

The power supply section is equipped with a bifilar wound power transformer with high balance of output impedance and output voltage.
In addition, four independent windings and four independent power circuits are used for digital, servo, audio, FL display, D/A converter, and D/A converter to reduce mutual interference.

The chassis uses a honeycomb chassis with honeycomb ribs for increased strength.

Equipped with Delete Play and Delete Random Play functions that allow you to skip songs you don't like or want to listen to from 6 CDs.
It is also equipped with functions such as auto program edit, time fade edit and one touch fade.
