1. Stereo audio, wide frequency response, high efficiency, low distortion and low noise, good sound effect
2. There is a volume adjuster, easy to adjust the sound
3. With power reverse connection protection, short circuit protection and overheat protection
4. Wide supply voltage and two input modes, higher efficiency
5. Material: PCB circuit board
6. Power supply voltage: DC 5-24V
7. Bluetooth version: 5.0
8. Transmission distance: about 15 meters (visible and unobstructed)
9. Number of channels: two channels (stereo)
10. Output power: 20Wx2 12V 4 ohms, 30Wx2 16V 4 ohms, 30Wx2 21V 8 ohms, 40Wx2 24V 8 ohms
11. Adapter speaker (40-200W): 4 ohms (5-16V power supply), 8 ohms (5-24V power supply)
12. Module protection mechanism: power reverse connection/short circuit/self-recovery overheating protection
13. Size: about 5.08x3.8x1.815cm

Precautions:
1. Keep a safe distance from the router to avoid wifi interference
2. It is recommended to use 5-24V DC power supply voltage, higher than 26V chip will burn
3. The power supply should be within 16V when connected to a 4-ohm speaker, and within 24V when connected to an 8-ohm speaker
4. The power supply current is recommended to be more than 2A
5. The speaker cable should not be too long, it is recommended to be within 1m
6. Pay attention to electrostatic protection. Before touching the power amplifier board, you need to release the static electricity on your hands to avoid the breakdown of the chip by static electricity. The Bluetooth chip is more sensitive to static electricity.
7. It is recommended that the rated power of the speaker is 40W and above to avoid the speaker being overheated and burned

1. 立体声音频，频率响应宽，效率高，低失真和低噪音，音效好
2. 有音量调节器，轻松调节声音
3. 具有电源反接保护、短路保护和过热保护

5. 材质：PCB 电路板
6. 供电电压：DC 5-24V
7. 蓝牙版本：5.0
8. 传输距离：约15米（可视无遮挡）
9. 声道数量：双声道（立体声）
10. 输出功率：20Wx2 12V 4欧，30Wx2 16V 4欧，30Wx2 21V 8欧，40Wx2 24V 8欧
11. 适配喇叭(40-200W)：4欧(5-16V供电)，8欧(5-24V供电)
12. 模块保护机制：电源反接/短路/自恢复过热保护
13. 尺寸：约5.08x3.8x1.815厘米

注意事项：
1. 与路由器保持安全距离，避免wifi干扰
2. 建议使用5-24V直流供电电压，高于26V芯片会烧毁
3. 接4欧喇叭时供电需在16V以内，接8欧喇叭时供电需在24V以内
4. 供电电流建议2A以上
5. 喇叭线不要太长，建议1m以内
6. 注意静电防护，接触功放板之前需先释放手上的静电，避免静电将芯片击穿，蓝牙芯片对静电比较敏感
7. 建议喇叭额定功率40W及以上，避免喇叭发热烧毁
