The power filter adopts six 50V3300UF Nikon capacitors, and the rectifier adopts a 25A imported rectifier flat bridge.

 

The PCB is made of 1.6mm thick double-sided sheet metal, with a thickness of 2.0A copper and a full process of tin spraying, ensuring good performance in passing large and small currents

 

Fully enclosed dust-proof Potentiometer, more stable performance, more durable than ordinary Potentiometer!

 

Add the currently advanced UPC1237 speaker protection circuit to make your horn safer.

All components of this product are original, simple and unadorned, with pure quality; The use of high-quality original components is not only a guarantee of safety and quality, but also a strong guarantee of achieving design goals in actual performance. The pursuit of high-quality products is our consistent goal.

 

A high-power new laser dark word TDA7294 integrated circuit with field transistor output, developed by SGS-THOMSON Microelectronics Company in Europe in the 1990s, is adopted. It has a rather daring taste. It has completely changed the sound quality of integrated amplifiers in the past, including raw, cold, and hard, and is widely used in the HI-FI field. The design of this chip focuses on sound quality. It has high voltage resistance, low noise, low distortion, soft and durable playback sound, as well as short-circuit current and overheating protection functions

 

 

Fever component assembly, subwoofer part composed of two new TDA7294 BTL outputs, low-pass filtering is designed according to the frequency adjustable design of home cinema (50-150Hz), with strong power! The left and right channels are respectively composed of two TDA7294, and the input coupling capacitor is made of WIMA 2.2UF coupling capacitor imported from Germany, making the sound sweeter! The signal-to-noise ratio of the board is also extremely high, and even if the ear is close to the speaker, no communication sound can be heard! It's the choice to upgrade the 2.1 amplifier!
