Description
 
The wide-range DC Integrated Amplifier which went back to the origin of amplifier, strove for the modification of a nakedness property, and adopted the circuitry which devoted in tone-quality serious consideration by the repetition of the audition.

Operational stability was realized not only to super-low-pass one but to the super-high region, and frequency characteristic DC-200kHz is attained.

The equalizer part of a high-order-accuracy 8 stone stream composition

The power-source part of a right-and-left independency of a large-sized 2 power transformer using is adopted.

Protection network loading of a hi-reliability design.

A tone control functionality with a tone selector

High precision 4-unit Detent volume

A pre-main separation possible / DC-AC main-amplifier input.

A unique tapes functionality.
