Super C4This is a pre-main amplifier that incorporates the technology used in high-end products such as.
Super C for the first stage amplifier which is easily affected by noise4For more information.
Pure amplification of the signal is achieved by operation that does not mix power noise etc.
MOS-FET is adopted in the driver stage of the power part.
Since the MOS-FET has a high input resistance and little distortion that occurs when switching between the driver stage and the final stage in a conventional class AB amplifier, it has ideal characteristics such as good high-frequency characteristics and linearity of small-signal amplification.
An f-shaped slit is installed to reduce the natural vibration caused by the material of the volume mount part.
The vibration characteristics of the mounting part have been improved and unique coloring has been proposed.
The NEW signal ground line is used to prevent noise contamination.
By unifying the reference points of the ground lines of various circuits that handle audio signals, it is possible to eliminate the ripple of the AC power supply and various noise components. This allows pure signals to flow through the main ground line, reducing the influence on audio signals.
Logical flow construction and relay type input selector are adopted.
Source Direct is installed.
