Product features:

Special note: the radiator must be installed!! Otherwise, it will heat up seriously and cause burning or frying! 1. This circuit is an official standard circuit, stable and reliable. 2. The filter adopts large electrolysis with a withstand voltage of 50V and a capacity of 2200uf. 3. Power supply voltage: double 12-36V ring, double 32V ring is recommended 4. Output power: 85W * 1 undistorted rated power, peak power 100W 5. Speakers above 100W can be easily pushed. Speaker impedance: 4-8 Ω 6. PCB size: 50 * 50mm Notes for use: The transformer with three wires must be used, and the double 12-32 can be used. The heat sink must be pasted by yourself Don't ask why not! Don't talk about theory! DC and battery are not good! Connect and explode! Double DC and double batteries are not good either. They burn when they are powered on.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
