Commentary
Pre-main amplifier of the point component series that adopts UHC-MOS.
Inheriting the design philosophy and technology of the S1 Series, we adopted a high-current amplifier UHC-MOS and composed of a single push-pull circuit in order to achieve both high sound quality and speaker drive performance with the smallest unit amplifier.
Left and right independent structure is adopted by independent amplifier circuit and heat sink layout.
This reduces interference between the left and right channels.
It is equipped with a source direct circuit. By turning on the source direct switch, the tone control circuit is bypassed and direct playback is possible.
It comes with a remote control that can turn the power on/off, adjust the volume, and switch the source.
The ease of use is improved by storing the infrequently used keys in the slide door.
