Product description How to Select the Audio Input Mode This amplifier board has two input modes: Bluetooth and 3.5mm AUX.The default setting is Bluetooth connection mode.If you need to use the AUX mode, please make sure that the Bluetooth connection is disconnected.If you need to use Bluetooth mode, first make sure there is only one device connected to the Bluetooth of the amplifier board, and make sure there is no signal input to the 3.5mm AUX, or unplug it directly. Parameter: Chip: TPA3116D2*2Input Mode: Bluetooth / 3.5mm AUXWork Voltage: DC 5V-24V (Recommend 12V or more, 5A or more)Channel: 2 channel Stereo OutputBluetooth version: Bluetooth 5.0Bluetooth transmission distance: 50 FtMAX Power Output: 100W x 2Match Speaker: 50 - 300W, 4 - 8Ω NOTE Only when the audio input is sufficient and the power supply voltage/current input is sufficient, can there be enough power output.The higher the power supply voltage, the greater the output power;The smaller the impedance of the speaker, the greater the output power. It is recommended to use a 4Ω speaker.Finally, please make sure that the power of the adapted power supply is greater than the actual working power of the AMP to ensure the maximum output power.Use a device with Bluetooth 5.0 or higher to connect to the amplifier; otherwise, Bluetooth may not function properly. Dual TPA3116 D2 Amplifier IC The maximum modulation frequency can reach 1.2MHZ, and the high-power output distortion is less than 0.1%, ensuring high-quality sound output Extra-large Heat Sink The extra-large heat sink can provide good heat dissipation for the continuous high-power output of the AMP, thus preventing the chip from being burned. Easy to Connect The universal 5.5mm*2.1mm DC power interface can be compatible with most of the DC power adapters. Supports 3.5mm audio input. Quick-connect terminal blocks make wiring easier Warm Reminder: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug it for a long time, you can unplug the DC plug on the machine.Properly increasing the voltage or reducing the speaker impedance can effectively increase the output power.It is recommended to use a power supply of 12, 5A or more, and the speaker power is 50-100W for the best effect! Package Includes: Bluetooth Power Amplifier Module * 1 Acrylic shell * 216mm Copper column * 49mm Screw * 820cm power cable * 1 Screwdriver * 1, Knob * 1
