Description
 
The Integrated Amplifier of the point component stereo series which adopted UHC-MOS.

In order to inherit the design philosophy and technology of S1 series and to aim at coexistence of high-quality-sound-izing and speaker drive capability with the magnification element of the minimum unit, large current type magnification element UHC-MOS is adopted, and it constitutes from a single push pull circuit.

Right-and-left independent structure is adopted according to the amplifier circuit of right-and-left independence, and a heat sink layout.
This is suppressing interference between channels on either side.

The sauce direct circuit is carried, a tone control circuit is bypassed by turning ON a sauce direct switch, and a direct play is possible.

on/off of a power source, volume regulation, and the remote control that can perform the change of sauce are attached.
The ease of using is raised by storing a key with little frequency in use into a slide door.
