ماژول آمپلی فایر بلوتوث AP50L:
XY-AP50L Mini Bluetooth 5.0 50W+50W Wireless Audio Power Digital Amplifier Board Stereo:
Product name: 50W+50W bluetooth stereo digital power amplifier
Product model: XY-AP50L
Supply voltage: DC: 5-24V (the higher the voltage, the higher the output power)
Bluetooth version: 5.0
Transmission distance: 15 meters (without obstacles)
Number of channels: left and right dual channels (stereo)
Adapted speakers: 30W-200W 4Ω 8Ω 16Ω

Note: The output power of the power supply must be greater than the output power of the amplifier, otherwise it will affect the sound quality
12V → 8Ω/15W + 15W, 4Ω/20W + 20W
15V → 8Ω/18W + 18W, 4Ω/over 30W + 30W
19V-→ 8Ω/32W + 32W, 4Ω/over 45W + 45W
24V → 8Ω/40W + 40W, 4Ω/more than 50W + 50W
Precautions for use:
1. Please use the power amplifier board as far as possible from the WIFI signal (router)
2. The recommended power supply voltage is DC 5~24V, if it exceeds 26V, the chip will burn out.
3. It is recommended that the power supply current exceeds 2A.
4. The speaker cable should not be too long and make sure it is suitable within 1 meter
5. Pay attention to static electricity protection. Before touching the power amplifier board, you must first release the static electricity on your hands to prevent the static electricity from breaking down the chip. Bluetooth chips are more sensitive to static electricity.
6. It is recommended to adapt the speaker with a rated power of 40W and above to prevent the speaker from heating up and burning
