Description

Product details:

PA-80 is a stereo amplifier with high output power and extremely low power consumption. It follows the HIFI design concept and performs well in practice, with stable and distortion free high-power output.

All aluminum alloy chassis+large radiator. Thick and elegant.
800W pure copper wire winding transformer, with strong power.
High dynamic amplification.
Symmetrical layout of left and right channels.
Circuit feedback circuit.
The performance remains stable even at high power output, allowing music to be perfectly presented.
Innovative design with VU meter, combining lighting effects and dynamic display, adding music fun.
1 pair of 2SA1941/2SC5198 transistors per channel drives 4 pairs of high-power 2SA1943/5200 transistors. The high dynamic performance is even better.
The collector current is 15A. It has strong current output capability and can provide sufficient power drive for the load.
The maximum breakdown voltage of the transmission can reach 230V, ensuring the stability and reliability of the power amplifier circuit during operation.
NAD10000uf/100V high-capacity array electrolytic capacitor improves the purity of the power supply, enabling the amplifier to obtain smooth and stable current.
F1 operational amplifier preamp circuit. High and low voltage can be independently adjusted.
Equipped with a power soft start circuit, effectively reducing the transient surge current during power on/off, minimizing the impact of power amplifiers on the power grid, and extending the lifespan of switches.
