NOTE:If supply power is low and output power is big, noise may be caused, turn down the volume and a bigger supply will be better
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,inchXY-P40Winchwill be searched and display; Click the inchXY-P40Winch,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.
1. Keep 2 meters away from router to avoid WIFI interference
2. 5~24VDC is recommended; upper than 26V, it will be damaged.
3. Driving 4Ω load, power supply must be under 16V; and driving 8Ω load, supply must be under 24V.
4. The supply current must be 2A at least.
5. The cable connecting speaker with module should be within one meter.
6. ESD protection, please release ESD on your hands before you contact the module.
7. 40W and upper power speakers is recommended.
1. Check the power supply if the LED is not bright.
2. If the LED is on, but Bluetooth device inchXY-P40Winchis not searched, check if the router is in the near, and keep away from the router.
3. 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.
4. 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.
5. 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.
