Note:

In order to improve the performance of the module, it is recommended to add a heat sink to the power amplifier chip in the application scenario of more than 20W*2

Instructions

• After the power is turned on, the blue indicator flashes quickly and enters the blue-ooth mode;

• after the "prompt tone" is broadcast, it enters the pairing mode and waits for pairing;

• the mobile phone Blue -tooth searches for "XY-P15W" (the name of the power amplifier board), click "XY-P15W" Connect, after the connection is successful, the "prompt tone" will be played, and the indicator light will be on for a long time, and the mobile phone music can be played.

• When the music is playing, the indicator light will flash slowly; after the Blue-tooth is disconnected, the power amplifier board is ready for the next pairing, the "prompt tone" will be played and then enter Pairing mode is waiting for pairing. The connection is as shown below

Precautions for use:

• Use the power amplifier board as far away as possible from the WIFI signal (router)

• The recommended power supply voltage is DC 8~24V. If it exceeds 26V, the chip will be burned.

• The power supply does not exceed 12V when connected to a 4Ω speaker, and the power supply does not exceed 24V when connected to an 8Ω speaker

• The power supply current is recommended to be more than 2A.

• The working power of the module exceeds 20W*2, and a heat sink needs to be added.

• The speaker cable should not be too long, and ensure that it is suitable within 1 meter.

• Pay attention to electrostatic protection. Before touching the power amplifier board, you need to release the static electricity on your hands to avoid the breakdown of the chip by static electricity. The blue-ooth chip is more sensitive to static electricity.

• It is recommended to adapt the rated power of the speaker to 30W and above to avoid the speaker from being overheated and burned.
