Bluetooth 5.0 Amplifier Board Stereo Audio Receiver- 50WPlus50W Digital Audio Amp Module- Dual Channel DC 5V-24V for Home Passive Speakers

The HiFi Bluetooth Amplifier Board with HIFI Excellent Sound With AUX and Bluetooth two audio input methods. Chip: TPA3116D2 (With AM interference supperession) With or Without Filter: Yes (Filtered sound is more round and clear ). Adaption Supply Voltage: 5-27V (Optional 9V/12V/15V/18V/24V, high power recommended high voltage). Speaker: 30W-200W, 4ohm-8ohm Number of Channels: Left and right stereo (Stereo) Transmission Distance: 15m (Without occlusion) Protection Mechanism: overheating, undervoltage, overheating, DC detection, short circuit protection. Power Supply Voltage 12V--8ohm speaker / 12W(Left channel)+12W(Right channel), 4ohm speaker / 20W+20W; 15V--8ohms / 18W+18W, 4ohm / greater than 30W+30W; 19V--8ohms / 32W+32W, 4ohm / greater than 45W+45W; 24V--8ohms / 38W+38W, 4ohm / greater than 55W+55W. The heat sink needs to be pasted onto the chip by yourself. The hotter the glue, the better the thermal conductivity. It is recommended to use 18v19v2v power supply with current above 3a. If there is only 9v12v or 1a and 2A power supply, it can also be used, but the power is small. Note that the maximum volume amplification may affect the sound quality.
