The features are as follows: 1. Using SMT high-speed placement machine to mount, high temperature reflow soldering, the performance is very stable, and the non-manual soldering process can be compared. Equipped with 4 sets of gain adjustments (note that technical support can be provided for batch orders, if it is a single chip, don't ask how to change it, the gain of this board is adjusted to the maximum by default). The ultra-small 70X57MM can be used for repairing, polishing active speakers, improving sound quality, or using multi-block multi-channel power amplifiers or 2.1 power amplifiers, which has many uses

• It has built-in output short-circuit and over-temperature and overload protection, and prevents the shock of switching on and off, which is rare in other 50W power amplifier boards
• Precautions for use: When the speaker impedance is 4 ohms, the working voltage must be less than 18V; when the speaker impedance is 6 ohms, the working voltage cannot exceed 24V; when the speaker impedance is 8 ohms, the working voltage cannot exceed 26V, and the polarity of the power supply should not Reverse
