100W+100W Bluetooth Audio Digital Amplifier Board Module AUX USB External Sound Card(Silver)

1. Amplifier output can only be connected to independent speakers or passive speakers2. The product does not include a power supply, you need to provide their own power supply DC9-24V, pay attention to the quality of the power supply, you need a pure DC power supply, with a complete rectifier filter, such as directly separate transformer will burn out3. In the case of sufficient audio input, power supply voltage/current is sufficient, there will be enough output power4. The higher the power supply voltage, the higher the output power, the lower the impedance of the speaker, the higher the output power5. Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifierParameters:1. Bluetooth version: 5.02. Transmission distance: 15 meters without blocking3. Signal-to-noise ratio: greater than 95dB4. Input mode: USB+AUX+bluetooth5. Number of channels: left and right dual-channel (stereo)6. Amplifier chip: TPA3116D2 (with AM interference suppression)7. Adaptable power supply: DC9-24V/5A or above (the higher the voltage, the higher the output power)8. Adaptable Speaker: 20-200W, 2-8Ω9.
