Description
@
The Integrated Amplifier which carries the newly developed audio element in an output stage.

Newly developed audio element Service Advertisement Protocol (transistor containing temperature-compensation functional) that built the temperature detection and the corrective network in the output stage is carried.
This solved the fluctuation of the operating point by the time loss at the time of carrying out external to the conventional power transistor, and the dynamic behavior which performs temperature compensation in real time mostly and to which the operating point follows the strength of a music signal dynamically is acquired.
Since a distortion is not changed by an output, the nakedness property in the sound volume in small - is stable.

With arranging a transmit and an amplifying circuit with a sufficient balance, the ill effect which it has on a tone quality is reduced.

In order to realize a purer music play, the Source Direct which shortest-izes signal channels of communication is adopted.

37 key unified remote control is equipped standardly and the operationality is improved.
