Blue tooth 5.0 20WX2 Stereo Power Digital Amplifier Board Module AMP Amplificador Home Theater 12V 24V 3.5mm AUX USB XY-AP15H

Description:
Product name: 20W+20W stereo blue tooth digital power amplifier
Product model: XY-AP15H
Supply voltage: DC: 8-24V (the higher the voltage, the greater the output power)
Blue tooth version: 5.0
Transmission distance: 15 meters (unobstructed)
Number of channels: left and right dual channels (stereo)
Adapted speakers: 30W-200W 4Ω 8Ω 16Ω
Protection mechanism: power supply reverse connection protection, short circuit protection, self-recovery overheating protection

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, the output power is greater than 20W+20W to add heat sink
12V→8Ω/10W+10W, 4Ω/16W+16W
16V→8Ω/15W+15W, 4Ω/more than 20W+20W
20V→8Ω/20W+20W, 4Ω/more than 20W+20W
24V→8Ω/30W+30W, 4Ω/more than 30W+30W
Precautions for use:
1. Use the power amplifier board as far away as possible from the WIFI signal (router)
2. The recommended power supply voltage is DC 8~24V. If it exceeds 26V, the chip will burn.
3. The power supply does not exceed 12V when connected to a 4Ω speaker, and does not exceed 24V when connected to an 8Ω speaker
4. The power supply current is recommended to be above 2A.
5. The working power of the module exceeds 20W*2, and a heat sink is required
6. The speaker wire should not be too long, and ensure that it is suitable within 1 meter
7. Pay attention to static electricity protection. Before touching the power amplifier board, discharge the static electricity on your hands to prevent static electricity from breaking down the chip. The Blue tooth chip is more sensitive to static electricity.
8. It is recommended to adapt the speaker with a rated power of 30W and above to avoid the speaker from heating and burning
