---------------------- ❤Product Introduction ❤-----------------------

1. This product has complete functions and high performance, especially suitable for high power HIFI music amplifiers.
2. This audio amplifier module has very high index parameters, the maximum modulation frequency is 1.2MHZ, and the distortion is less than 0.1%.
3. Red gray ring inductor +684 film capacitor, with low loss, high bandwidth, HiFi and other characteristics.
4. Support AUX and audio input and potentiometer to adjust the volume, easy to use.
5. Adopt copper DC female head and shed fence terminal, bear high current, no heat, no damage to the circuit, good wiring, and no short circuit.
6. Using 5.0 version, it has higher transmission efficiency and longer transmission distance.

Note:
1. The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low‑power standby state. Turn off the power completely or unplug the DC plug on the machine for a long time.

2. Do not use it outside the range of voltage and current.3. Only when the audio input is sufficient and the power supply voltage/current is sufficient, will there be sufficient output power. The higher the power supply voltage, the greater the power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative power.
