Product name: 20W+20W stereo bluetooth digital power amplifier
Product model: XY-AP15H
Supply voltage: DC: 8-24V (the higher the voltage, the greater the output power); Bluetooth version: 5.0; Transmission distance: 15 (unobstructed); Number of channels: left and right dual channels (stereo); Adapted speakers: 30W-200W 4 ohm 8 ohm 16 ohm
Protection mechanism: power supply reverse connection protection, short circuit protection, - overheating protection
Note: The output power of the power supply must be the output power of the amplifier, otherwise it will affect the sound Quality, the output power is 20W+20W to heat sink 12V-8 ohm/10W+10W, 4 ohm/16W+16W
16V-8 ohm/15W+15W, 4 ohm/more than 20W+20W
20V-8 ohm/20W+20W, 4 ohm/more than 20W+20W
24V-8 ohm/30W+30W, 4 ohm/more than 30W+30W
Precautions for use:
1. Use the power amplifier board as 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 12V when connected to a 4 ohm speaker, and does not 24V when connected to an 8 ohm speaker
4. The power supply current is recommended to be above 2A.
5. The working power of the module exceeds 20W x 2, and a heat sink is required
6. The speaker wire should not be too long, and that it is suitable within 1 meter
7. Pay attention to static electricity protection. touching the power amplifier board, discharge the static electricity on your hands to prevent static electricity from breaking down the chip. The Bluetooth 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
