1. Silent fan: reduce the overall temperature of the module, for the power supply, amplifier chip, filter capacitors and other heat dissipation, reduce the temperature rise and the impact of temperature rise on the sound quality, to ensure that the components of the long-term stability of work
2. Dial keys: easy to operate
3. Bluetooth version: 5.0 (no cover, 15 meters)
4. Input mode: AUX+Bluetooth+USB (dial-wheel button to switch modes and songs)
5. Number of channels: 2.1 channels (left channel + right channel + subwoofer)
6. Amplifier chip: TDA7498E
7. Adaptable power supply: DC 15-36V (below 9V undervoltage protection, can also support 12V power supply)
8. Adaptable speakers: 30-200W, 4-8 ohms.
9. Output speakers: less than 160W for left and right channels, less than 220W for subwoofer
10. Protection mechanism: anti-reverse connection/under-voltage/overheating/short-circuit protection
11. Size: about 14.5 x 12.6 x 2.8cm
12. Weight: about 327g

Attention:
1. Sufficient output power will only be available if the audio signal input is large enough and the power supply voltage/current is high enough
2. The higher the power supply voltage, the higher the output power, the lower the speaker impedance, the higher the output power, please ensure that the power of the adapted power supply is greater than the actual working power of the amplifier

1. 静音风扇：降低模块整体温度，为电源、功放芯片、滤波电容等散热，减少温升以及温升对音质的影响，确保元件长期稳定工作
2. 拨轮按键：操作简单方便
3. 蓝牙版本：5.0（无遮挡，15米）
4. 输入方式：AUX+蓝牙+USB（拨轮按键切换模式和歌曲）
5. 声道数：2.1声道(左声道+右声道+低音炮）
6. 功放芯片：TDA7498E
7. 适配电源：DC 15-36V（低于9V欠压保护，也可支持12V供电）
8. 适配喇叭：30-200W，4-8欧姆
9. 输出喇叭：左右声道小于160W，低音炮小于220W
10. 保护机制：防反接/欠压/过热/短路保护
11. 尺寸：约14.5 x 12.6 x 2.8cm
12. 重量：约327g

注意：
1. 在音频信号输入足够大，电源电压/电流足够大的情况下，才会有足够的输出功率
2. 电源电压越高输出功率越大，喇叭阻抗越小输出功率越大，请确保适配电源功率大于功放实际工作功率
