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 * 50m

This version has included rectification and filtering lines, so you must use a transformer with three lines. Double AC 12-32V can be used, and DC power supply is not allowed. You must remember to burn it when you install it! Remember! Remember!

Pay special attention to the following 5 points:

1. The chip is very hot. In any case, a sufficiently large radiator must be installed when it is powered on.

2. The chip must be insulated from the radiator, otherwise it will burn.

3. It is a good choice to use a standard ring transformer as the power supply, instead of using an adjustable power supply.

4. All wires shall not be connected reversely or wrongly, or the chip will be burned.

5. Electrolytic capacitor and diode pins can be positive or negative, and cannot be reversed.

6. This baby is mono, and it needs to buy two sets of dual channels.
