Description：
● Adopting Class A power amplifier circuit with full balance, full symmetry, differential input to differential BTL power output:
●The input stage adopts common emitter and common base amplifier circuit;
●The circuit has the characteristics of large dynamic, high conversion rate, small harmonic distortion, low noise, good transient response, high linearity, wide frequency response range, etc.;
● The voltage amplifier stage adopts common base circuit to further improve the open-loop gain of the power amplifier and widen the high-frequency response to the extreme;
●The output stage adopts three-stage Darlington drive, and high-power audio dedicated tubes are output in parallel, which greatly improves the damping coefficient of the power amplifier;
●The power amplifier front and rear stages adopt the power supply mode of high front and low back, which gives full play to the advantages of the circuit and further improves the performance of the whole machine;
●It uses a 600W high-quality ring transformer, up to 80,000 microfarad audio-specific custom capacitors, and high-power audio-specific famous tubes in parallel output to provide a large current output capacity;
●Each channel outputs 165W/8Ω high power, with abundant power reserves, easily taming major brand speakers;
●Adopting Tianyi's classic independent cavity isolation structure design, the mutual influence of left and right channel signals is reduced to a minimum;
●Perfect power amplifier protection circuit (short circuit protection, overheating protection, DC protection, etc.);
●The high-frequency sound quality is clean and delicate, soft and smooth, the mid-frequency is thick, and the texture and analytical power of the music are quite excellent, the elasticity and weight of the low-frequency are quite accurate, and the low-frequency dive is bottomless.
