The biggest feature of this machine lies in the design of power supply and output cattle.
Power transformer: it adopts high-quality Z11 iron core wound large margin transformer with sufficient margin reserve to ensure sufficient power supply when playing large dynamic and sub-low frequency. In addition, the front stage filament, the left channel rear stage filament, the right channel rear stage filament, the front stage high voltage and the rear stage high voltage all adopt independent windings, and the working voltages do not interfere with each other.
Output transformer: it is wound with high-quality Z11 iron core and unique 4-layer winding method. Make the effective output frequency band reach 15Hz ~ 30kHz. It can effectively show the tone and details of music.
Inductance: there are two inductors wound with high-quality Z11 iron core. Compared with other poor merchants who castrate the choke or adopt one inductor, the smoothness of power supply and low-frequency submergence of sound quality cannot be compared with our design.
Power supply: the rear stage and the front stage adopt independent power supply, and their independent inductors and 7 large capacitors are used for filtering and energy storage. It is rare to find all over the whole network. Compared with the mainstream, the full sound and low-frequency low sense of a large capacitor will be greatly improved.
Pure rear stage: This machine can be used as a pure rear stage function and can be connected to this group of input ports through the front stage (Note: when receiving pure rear stage input, the volume potentiometer of this machine will not work).
Balanced input: This machine supports balanced input and can be connected with the balanced output of high-end sound sources. It is characterized by larger dynamics and clearer background.
Working point adjustment and monitoring function: this function can accurately adjust the working point of each high-power tube, which is very practical when upgrading the electron tube.
Power monitoring meter: one for each channel. The dynamic power monitoring meter can monitor the power transfer out status of each channel in real time.
The machine adopts large signal shed + small signal PCB wiring, with less interference and more stable performance. Large signal shed reduces internal resistance, small signal PCB wiring interference is small, and product consistency is better. It is a natural and perfect matching method. After careful design and proofreading by professional listeners in Hong Kong and Macao, the machine has fine sound quality, rich, sweet and full hall sound, and has a stronger sense of leaving the box and being on the spot in large dynamic situations.
