1. This audiopower amplifier module has two audio enter strategies: one is Bluetooth enter, theother is AUX enter, Bluetooth mode is most popular.
2. The powersupply with the board is essential. The ripple of the chosen powersupply have to be small. An influence provide with a big ripple will trigger the bottomnoise of the ability amplifier board to extend and there shall be present noise.
3. Generally usedspeakers are usually 4-8 ohms and can be utilized.
4. The sound isdistorted, please flip down the overall quantity or change to a better voltageadapter energy provide.
5. TheMAIN—VOLUME knob is used to regulate the principle quantity. Proper-handed major volumeincreases, left-handed major quantity decreases.
6. The soundquality isn’t solely associated to the ability amplifier module, but in addition associated tothe energy provide, sound supply and the complete sound system.
Bundle Consists of: 1 pcs x Amplifier Board
Undertake TPA3116D2 chip with AM anti-interference operate. Bluetooth and AUX operate: Bluetooth model 5.0, lengthy transmission distance.
Bluetooth model: 5.0 (unshielded, 10m), enter sensitivity: 500mV, audio enter: AUX + Bluetooth, channel: 2.1, chip: TPA3116D2 (with AM anti-interference operate), energy: DC12-24V / 5A.
Adapter speaker: 20 -100W, 4-8Ω.Output energy: ≤50W (R and L channels), ≤100W (subwoofer).
This Amp Board Has Overheat Safety, Reverse safety, Circuit Safety, Over-voltage and Underneath-voltage Safety.
Notice:When the audio enter is ample and the ability provide voltage/present is ample, there shall be ample output energy.The upper the ability provide voltage, the upper the output energy, and the smaller the speaker impedance, the upper the output energy. Please be sure that the ability of the adaptor is bigger than the precise working energy of the amplifier.
