1.It is carefully designed in all directions, and the interior of the machine is designed with an integrated and ultra-high degree of integration.It brings together the difficult technical design of weak-signal analog amplifier circuit, digital logic circuit, vacuum tube high-voltage amplifier circuit, low-signal transmission circuit, and stabilized power supply circuit.
2.The volume attenuation method adopts the highest fever specification design-purely mechanical switching of signals.All use original imported Japanese OMRON ultra-low signal special relays, and only a single relay is strobe for each level of volume to ensure that the audio signal loss is minimized.This effect is far better than the common carbon film sliding potentiometer or multi-resistance sliding potentiometer volume attenuation method, which can be said to be a world of difference!
3.The output coupling capacitor uses 4 original imported German Mundorf M-CAP capacitors.The Mcap series completely combines the characteristics of sound quality with the advantages of film capacitors, which in turn shows a very noble sound quality, with a calm and calm performance, a clear and quiet background.The application in the system will show better details and transparency, and richer music details will be obtained.
4.The shell panel is simple and generous, with a remote control and LCD screen display, and the interface is friendly.Each channel can set and store parameters separately, and has functions such as fast switching of input channels, loading selection of input channels, adjustable output positive and negative phase, adjustable display brightness, and silent boot protection delay.
5.Use 4 12AU7/ECC82 tubes with strictly matched parameters to ensure that the vacuum tube amplifier circuit keeps working in the best condition.
6.The CPU processor core running the embedded software system uses the enhanced high-performance ST ST's ARM Cortex-M3 STM32F103VET6 to ensure sufficient processing performance.
7.The AC input terminal uses a high-purity oxygen-free copper OFC-wound conjugated filter inductor to isolate clutter interference from the external power grid and improve the audio effect..
8.Each phase of the power supply is all supplied by a high-precision regulated power supply to ensure that the voltage ripple is minimized and the audio characteristics are optimal.In addition, each digital circuit and each analog circuit are completely separated from the transformer coil power supply, minimizing the crosstalk of various circuits to achieve the ultimate performance effect..
