When the power supply is seriously insufficient, the speaker will make a “dida” sound, even without heavy.It is recommended to connect 2 channels of 4 ohm 3W (5W) speakers; if you connect 2 ohm speakers, the power amplifier chip will heat up, causing the chip to burn.Pay attention to stable electricity protection. It is easy to generate static electricity when the weather is dry. In the process of using the user, please use the static electricity on the conductor to operate the decoder board to avoid the decoder chip being destroyed by static electricity.During use, the mobile phone and the bluetooth decoder board should not be blocked by obstacles such as walls, and should be kept away from the metal shield as much as possible; blocking will reduce the transmission distance, and in serious cases, the music will be stuck and intermittent; the decoder board can be properly adjusted. The angle of the phone adjusts the optimum state of the connection signal.Instructions:After the power is turned on, the blue indicator light is on and enters the Bluetooth mode; after the “Beep” is broadcast, the pairing mode is entered to wait for pairing; the mobile
Use for home, office and industry electrical
LED indicator : bluetooth mode blue unclouded is on
On-board stereophony Class D power amplifier module, maximum output 5W+5W
The decoder board supplies 3.7-5V, if it is higher than 5.5V, the chip will be burnt. Do not reverse connect the positive and negative poles of the power supply. The reverse will burn the chip.
Support bluetooth version 4.2, 3.7-5V power supply, support robotlike connection function
