The Integrated Amplifier which supplied the audio technology of the SANSUI.
It is the structure which inherited the technology of the high order model.

The large-sized transformer is adopted as a power-source part.

The amplifier part consists of semi- complimentary Darlington SEPP-OTL circuitries.
Moreover, the fuse for a power transistor protection is adopted.

Functionalities, such as the selector of tuner priority, a row / high filter, a loudness, a tapes monitor, a mode switch, and three kinds of speaker switchings, are carried.

The mic jack and the DIN termination are carried in the front panel.
The high impedance type mic is supported.
