Feature:
1. Class a design
2. Internal split power supply layout
3. Rear stage dual mono design
4. Strong current driving force, easy to drive low sensitivity speakers
5. Short cut signal, low loss, less noise pollution, and careful sound adjustment
1. The front stage of the British horseshoe gall bladder is used as the model, and the field effect tube and gall bladder are mixed to form the front stage
Level amplification circuit, restore sweet and full music.
2. The front stage adopts constant current source stabilized power supply, with stable voltage and low internal resistance, fast current supply,
Make music details clear and harmonic rich.
3. The distribution of circuit wiring and ground wire is extremely exquisite, and the mutual interference is small and the loss is low. Fine tuning
The feedback and coupling capacitance of the circuit make the frequency characteristic smooth and comfortable.
4. Designed with the concept of split power supply, the left and right rear stages, the transformer and the front stage are all independent section amps
Put an end to all kinds of interference from the design, and the music is pure and pleasant.
5. Set the equal loudness switch, and when listening to music at a low volume,
To compensate for the loudness of the high and low sounds, the music is also full.
6. Set two levels of class a power, - level is environmental protection and low-carbon sound, - level is the pursuit of excellence
The mellow sound of.
