1. Chip solution: TPA3116D2 (with AM interference suppression function)2. With or without filter: Yes (the sound is more mellow and clear after filtering)3. Adapted supply voltage: 5~27V4. Adapted speakers: 30W~200W, 4ohms, 8ohms5. Number of channels: left and right dual channels (stereo)6. Bluetooth version: 5.07. Bluetooth transmission distance: 15 meters (unobstructed)8. Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection9. Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the greater the ohms of the speaker, the lower the relative sound power, please pay attention!10.
