All items ONE-YEAR WARRANTY !!!
We can Declare the Value of the Order as Customer's Remark!!!
Low-distortion reverse Darlington circuit: the signal uses relay switching input (the whole machine is equipped with 5 fever-class relays) to make it reach the power amplifier without attenuation;
It adopts six 10000uF/50A (capacitors produced by the British old capacitor factory NOVER, its characteristics are excellent, the tangential loss angle is small, the internal resistance is small, the distortion is very low (third harmonic distortion -98dB), the current is large (the instantaneous discharge capacity is strong) ,long lasting.
The capacitor sounds clean, the sound is mellow, the tone is neutral and sweet. The large filter capacitor and the 50A high current bridge stack (Sanken) make it get enough energy supply;
1 pair (2SA1295/2SC3264 Sanken patented LAP technology, high-frequency multi-emitter transistor, 200 watts, high-power, high-frequency, low-frequency, full-flexibility, high-pitched, high-pitched, non-rich, and not sturdy) Sanken high-power tube and Push tube, 8 Japanese ELNA10uF/100A coupling capacitors, Japanese ALPS potentiometer, clock mysterious high-quality high-power transformer, high-purity binding posts, etc.
The overall sense of hearing is small distortion, fast speed, wide and stable sound field, transparent sound, accurate positioning
1, the circuit uses the return to Darlington circuit, small distortion and other characteristics
2. The relay switching mode input is adopted, and the signal is attenuated to reach the power amplifier.
3, the volume control uses the Japanese (ALPS) potentiometer to make the music more pure and true
5, the power supply uses six 10000UF/50V large filter capacitors, so that there is more energy
6, the use of high-power transformers, make the circuit more stable, the sound field is more open, the human voice is more pleasant 7, the speaker terminal, the use of high-purity copper speaker seat
8. The machine phase adopts the shock-absorbing rubber material machine foot to make it work more stable.
9. The volume remote control adopts the traditional aluminum alloy remote control of Zhongshen, showing the noble and generous
