★Features:
1. Adopt fully balanced, fully symmetrical, differential input to differential BTL power output Class A power amplifier circuit:
2. The input stage uses a cascode amplifier circuit
3. High circuit dynamics, high conversion rate, low harmonic distortion, low noise, good transient response, high linearity, wide frequency response range, etc.
4. The voltage amplifier stage adopts a common base circuit, which further improves the open-loop gain of the power amplifier and broadens the high-frequency response to the extreme.
5. The output stage adopts a three-stage Darlington driver, and the high-power audio dedicated name tube is output in parallel, which greatly improves the damping coefficient of the power amplifier.
6. The front and rear stages of the power amplifier adopt the power supply method of high front and low back, giving full play to the advantages of the circuit and further improving the performance of the whole machine
7. Using a 600W high-quality ring cow, up to 80,000 microfarads of audio dedicated custom capacitors, high-power audio dedicated name tubes parallel output, providing maximum current output capability
8. Each channel outputs 165W/8Ω high power, and the power reserve is abundant and rich, which can easily tame the speakers of major brands
9. Adopt Tianyi's classic independent cavity isolation structure design to minimize the mutual influence of left and right channel signals
10. Perfect power amplifier protection circuit (short circuit protection, overheat protection, DC protection, etc.)
