1. Bluetooth version: 5.0 2. Operating voltage: DC8-24V 3. Transmission distance: 15 meters (visible and unobstructed) 4. Number of channels: dual-channel (stereo) 5. Adaptable speaker power (30W-150): 4 ohms (8-12V power supply), 8 ohms (8-24V power supply), 16 ohms (8-24V power supply) 6. Module protection mechanism: reverse power supply protection, short-circuit protection, self-recovery overheating protection 7. Note: to improve the performance of the module, it is recommended to work more than 20W x 2 application scenarios under the amplifier chip plus heat dissipation 8. Anti-static bag packaging, acrylic panels have a protective film, please tear off when assembling 9. Module size: about 5 x 3.3 cm Operating instructions: 1. After turning on the power, the blue indicator light will flash quickly to enter the Bluetooth mode 2. Enter pairing mode and wait for pairing after announcing the beep 3. Mobile phone bluetooth search to XY-P15W (amplifier board device name), click XY-P15W connection 4. After successful connection, play the tone, the indicator light will be on, you can play the music on your cell phone, and the indicator light will flash slowly when playing the music 5. Bluetooth disconnect the amplifier board to prepare for the next pairing, and play the tone after entering the pairing mode waiting for the pairing Precautions for use: 1. Amplifier board to use as far away from WIFI signals (router) 2. Recommended power supply voltage DC 8-24V, more than 26V, the chip will be burned 3. Connect 4 ohm speakers when the power supply does not exceed 12V, connect 8 ohm speakers when the power supply does not exceed 24V 4. Recommended power supply current is more than 2A 5. Module working power more than 20W x 2, need to add heat sinks 6. The speaker cable should not be too long, ensure that 1 meter or less is suitable 7. Pay attention to electrostatic protection, contact the amplifier board before the need to release the hand of static electricity, to avoid static electricity will chip breakdown, bluetooth chip is more sensitive to static electricity 8. It is recommended to adapt to the speaker rated power 30W and above, to avoid burning the speaker heat
1. 蓝牙版本：5.0 2. 工作电压：DC8-24V 3. 传输距离：15米（可视无遮挡） 4. 声道数量：双声道（立体声） 5. 适配喇叭功率（30W-150）：4欧姆（8-12V供电）、8欧姆（8-24V供电）、16欧姆（8-24V供电） 6. 模块保护机制：电源反接保护、短路保护、自恢复过热保护 7. 注意：为提高模块性能，建议工作超过20W x 2的应用场景下功放芯片加散热 8. 防静电袋包装，亚克力面板上有保护膜，组装时请撕掉 9. 模块尺寸：约5 x 3.3 cm 操作说明： 1. 接通电源之后，蓝色指示灯快闪，进入蓝牙模式 2. 播报提示音后进入配对模式等待配对 3. 手机蓝牙搜索到XY-P15W（功放板设备名称），点击XY-P15W连接 4. 连接成功后播放提示音，指示灯长亮，即可播放手机音乐，播放音乐时指示灯慢闪 5. 蓝牙断开连接后功放板准备下一次配对，并播放提示音后进入配对模式等待配 使用注意事项： 1. 功放板使用尽量远离WIFI信号（路由器） 2. 推荐供电电压直流8-24V，超过26V，芯片会烧毁 3. 接4欧姆喇叭时供电不超过12V，接8欧姆喇叭时供电不超过24V 4. 供电电流推荐2A以上 5. 模块工作功率超过20W x 2，需要加散热片 6. 喇叭线不要太长，保证1米以内合适 7. 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 8. 建议适配喇叭额定功率30W及以上，避免喇叭发热烧毁
