The Integrated Amplifier which carries the newly
developed audio element in an output stage.
In the conventional case,
the temperature detection and the corrective network performed to the power
transistor by external, the time loss from which heat is transmitted by this
arose, and the operating point was swinging. The gap of an amplification factor
to a music signal occurred by this, and it had become a distorted cause
especially at the time of a small signal.
However, 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 was carried, and the dynamic behavior
to which the operating point follows the strength of a music signal dynamically
is acquired by performing temperature compensation in real time mostly.
Since a distortion is not changed by an output, the nakedness property in
the sound volume in small - is stable.
By arranging a transmit and an amplifying circuit with a sufficient balance,
disorder of the signal in a circuitry etc. has reduced various ill effects
which it has on a tone quality.
In order to realize a purer music play, the Source Direct which
shortest-izes signal channels of communication is adopted.
