Description
 
The Integrated Amplifier which pursued simple & straight thought further.

In order for wiring material, wiring, etc. to prevent having a bad influence on a music signal, proper arrangement of volume or switches is thoroughness-ized. This eliminated complicated leading about of the course to an input terminal or a speaker terminal, and shortest-ization of a signal course is realized.

The large-sized toroidal transformer is adopted as a power-source part.
A toroidal transformer is what rolled the coil and has the capability to have excelled in prevention of the stable supply of current, leakage flux reduction, and vibration etc. in the doughnut-like ring core compared with the transformer with conventional EI form and cut core.
Furthermore, this transformer is polished up with technology original with DENON, and it carries as a Super-Stable-Toroidal power source.

The New super optical ClassA circuit is carried in the power amplifier part.
By the newly developed bias control circuit, it amplifies as a pure Class-A to a general listening level, and is amplifying as a non switching Class-A which was excellent in the improvement of crossover distortion or switching distortion at the time of the Oide power.
While using the optical element for transfer of the control signal from a bias control circuit to a bias circuit and eliminating completely the mutual intervention between the main signal system and a bias controlling circuit, high speed-ization of bias control is realized.

Low impedance volume is adopted and the signal to noise ratio in a general listening level and a frequency response are raised by lowering the impedance of a volume control circuit.

The Source-Direct function is carried and a simple signal course is realized by bypassing control circuits, such as Bass, Treble, Balance, Loudness, and Subsonic, if it turns ON.
