Operation specification
Supply the module, the blue LED is on, and it goes into Bluetooth mode;Waiting for pairing after playing the audio tone; Turn on phone Bluetooth,"XY-P40W"will be searched and display; Click the
"XY-P40W",it will connect to the board. It connects successfully with an audio tone; After this you can play the music. The power amplifier board will prepare for the next pairing with an audio tone, When the Bluetooth is disconnected.
NOTE:
- Keep 2 meters away from router to avoid WIFI interference
- 5~24VDC is recommended; upper than 26V, it will be damaged.
- Driving 4Ω load, power supply must be under 16V; and driving 8Ω load, supply must be under 24V.
- The supply current must be 2A at least.
- The line connecting speaker with module should be within one meter.
- ESD protection, please release ESD on your hands before you contact the module.
- 40W and upper power speakers is recommended.
Fault Check
- Check the power supply if the LED is not bright.
- If the LED is on, but Bluetooth device "XY-P40W"is not searched, check if the router is in the near, and keep away from the router.
- The speaker tapped when power on.
- Check that the speaker load is so small that the current through the speaker is enough for chip goes into DC protection. Try to lower the supply and restart.
- Check that if the power supply is low that cannot drive the speaker. 2A power supply current is ok.
- Floor noise in speaker when playing
- Play another music to verify the noise is not related with music itself.
- Replace the speaker to check If the noise is caused by speaker itself.
- Replace the power supply to check If the noise is caused by unstable power.
- It plays intermittently
- Check if the temperature of the board is high, and it goes into thermal protection.
Check if the Bluetooth is unstable, adjust the angle between the connected device; And Check if a WIFI source is in the near
