This model has been developed with thorough understanding of the basics of pre-main amplifier.

The power supply section is equipped with a 15,000 μ Fx2 large-capacity capacitor to provide a stable current supply.
In addition, consideration is given to the separation of the power supply circuit and the layout around the power supply to prevent contamination of noise.

To make the most of the characteristics of analog records, we have adopted a phono equalizer using a low-noise FET and audio IC. It is compatible not only with MM type cartridges but also with MC type cartridges.

There is a source direct switch which is connected directly to the master volume from the selector switch. This allows you to listen to all sources directly connected to the power amplifier.

The input terminals are Line 5, and the tape input / output terminals are 2 systems.
Apart from the usual source selector, the tape monitor switch allows for easy editing of tapes 1 to 2.

The master volume uses Marantz's unique resistance change characteristics to provide a natural sound volume as the knob rotates.
