Understanding the XY-P15 Digital Audio Bluetooth 5.0 Stereo Amplifier



  • 100% brand new and high quality.
  • Made of high quality material, this power amplifier chip has high fidelity and two-channel stereo sound quality.
  • It have back-connection protection of power supply, short circuit protection and self-recovery overheat protection, safe to use.
  • It also can be directly connected to smartphone, MP3 player.
  • Most mainstream music format can be decoded, and it has an effective transmission distance with 15 meters unobstructed connection.
  • It also comes with a volume adjustment function, which rotates the chirp potentiometer clockwise to zoom in and counterclockwise to decrease.


  • Working voltage: DC8-24V
  • Bluetooth version: 5.0
  • Transmission distance: 15m (Visible occlusion)
  • Number of channels: 2 Channels (Stereo)
  • Output power(@1KHz): 16W x 2 @12V 4Ω, 10W x 2 @12V 8Ω, 15W x 2 @16V 8Ω, 20W x 2 @20V 8Ω, 30W x 2 @24V 8Ω(Need to add radiator)
  • Adapted horn: 4Ω(8-12V Power supply), 8Ω(8-24V Power supply), 16Ω(8-24V Power supply)
  • Modular protection mechanism: Back-connection protection of power supply, Short circuit protection, Self-recovery overheating protection
  • Size: app.50 x 33 x 14mm/1.97 x 1.30 x 0.55in

Use precautions:

1. Use power amplifier board as far away from WIFI signal as possible (router).
2. Recommended supply voltage is 8-24V, over 26V, the chip will burn out.
3. The power supply shall not exceed 12V for 4 ohm speakers and 24V for 8 ohm speakers.
4. Power supply current recommendation more than 2A.
5. The working power of the module exceeds 20W x 2, and the radiator is needed.
6. Horn line should not be too long to ensure that 1 meter is suitable.
7. Pay attention t oelectrostatic protection, contact between power amplifier boards need to release the hand electrostatic, to avoid electrostatic chip breakdown, Bluetooth chip is more sensitive to electrostatic.
8. It is suggested that the rated power of the horn is adapted to 30W or more to avoid the burning of the horn due to heat.

How to use the XY-P15 Digital Audio Bluetooth 5.0 Stereo Amplifier

1. After the power is turned on, the blue LED indicator light flashes quickly which means it enters the Bluetooth mode.
2. After the “Beep”, the amplifier board is waited for pairing.
3. Searching for “XY-P15W”(the power amplifier board device name)with mobile phone Bluetooth, then clicks “XY-P15W” to pair.
4. After connected, it will “Beep” and the LED indicator is always light up, you can play the music of the mobile phone, and the indicator flashes slowly when playing music.
5. After the Bluetooth is disconnected, the power amplifier board will “Beep” and prepares for the next pairing.


Wrapping up

The XY-P15 Digital Audio Bluetooth 5.0 Stereo Amplifier is a good thing to have. You can use rechargeable batteries to supply it and mount in metal holder on one of your speakers.
