This product adopts PAM8406 digital power amplifier, 2 channels of 5W power amplifier, good quality, excellent sound quality, suitable for Bluetooth transformation of 3-5W small speakers. Product name: Bluetooth digital power amplifier module Product model: XY-P5W Power supply voltage: 3.7~4.2V lithium battery/Micro USB DC5V Bluetooth version: 5.0 Transmission distance: 15 meters (visible and unobstructed) Number of channels: two channels (stereo) Output power (@1KHz): 3W*2 @5V 4Ω 5W*2 @5V 2Ω Adapter speaker: 2 ohm 5W 4 ohm 3W 8 ohm 2W protection mechanism: Reverse power protection Overheating protection Instructions: After the power is turned on, the blue indicator light flashes quickly and enters Bluetooth mode; after the "beep tone" is broadcast, it enters pairing mode and waits for pairing; the mobile phone Bluetooth searches for "XY-P5W" (power amplifier board device name) and clicks "XY-P5W" Connect, play the “prompt tone” after the connection is successful, the indicator light is long, you can play mobile phone music, the indicator light flashes slowly when playing music; after the Bluetooth is disconnected, the amplifier board is ready for the next pairing, and enter the “prompt tone” after entering Pairing mode is waiting for pairing. Matters needing attention when using 3.7V lithium battery: 1. When using battery power, the decoder board automatically shuts down when the battery voltage is lower than 3.3V. It needs to be re-powered or fully charged to short-circuit the on/off contact for 2 seconds to work properly. 2. When using battery power, if the battery voltage is too low, there may be "sizzling" noise. In this case, the battery needs to be charged. 3. Since there is no lithium battery charging protection circuit on the decoder board, it is recommended to use a lithium battery with a protection board. 4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to charge the battery directly. 5. The power of the power supply must be greater than 10W. It is recommended to use a power supply of more than 20W. If the power supply is not enough, the sound quality will be affected.
