1pc DP1 TPA3116D2 2.1 digital amplifier board 50W*2+100W subwoofer Bluetooth 5.0
Buyers please be aware:
95% of the people said that the power is enough, 5% of the people labeled power is not enough, please test the power of the power supply in their hands.The power of the power supply in their hands, if you only get 12V 2A power supply with the board, so that the evaluation is definitely insufficient power. 12X2A = 24W. power supply is not powerful, the amplifier can not output enough energy, remember, it is recommended to get enough power power supply to 19V 4.7A or more can be, thank you!
Product Description:
1 The total capacitance is increased to nearly 10,000UF (4700UFX2), which allows for a better signal-to-noise ratio, good low frequency strength, and a constant source of energy.
2 rich adjustment options, adjustable subwoofer frequency, left and right channel high and low adjustable
3 redesigned low-pass filtering, subwoofer thrust more powerful
4 audiophile low loss red ring inductor output
5 4 pieces of NE5532 audiophile op-amp as a preamp, low-pass amplification, etc.
This board does not contain an external power supply, you need to match their own. You can also use the laptop power supply.
Main parameters:
Power supply: DC12-25V
Interface: outer diameter 5.5MM inner diameter 2.5MM
Power: 2X50W+100W subwoofer (tested under DC24V)
Line board size: 95x150MM
The output power varies under different voltages.
Operating voltage range: DC 9-25V (current 3-4A or more, if you want more power, it is recommended 19-24V/4-5A or more)
Audio input sensitivity: 500-800mV, frequency response range: 20Hz-20KHz.
Speaker impedance: left and right channel speakers: 3.5-8 ohms, bass speaker impedance: 2-8 ohms.
Maximum output power: 50W (left channel) + 50W (right channel) + 100W (bass channel)

Notes on operation:
1. Before turning on the power, rotate the knob to the leftmost side, and then go to the input DC power supply, so that the power on completely without impact
2. Shutdown do not first directly unplug the input DC power, but first turn the volume knob left to the minimum and then unplug the DC power, so that the shutdown without any impact
3. The board's leftmost power access light, always on, not controlled by the switch.
4. This board is designed specifically for home and car 2.1 system, with passive 2.1 speakers, you can get a very shocking and realistic live effect, but also to achieve high-fidelity 2.0 HIFI music playback.
5. The core of the board is super quiet, but this board because it does not come with an enclosure, so a good power and signal cable is essential. It is best to wear on the knob or connect the signal ground, otherwise direct manual touch the board or touch potentiometer will sense interference sound.
6. It is best not to use the wood shell to do the chassis, wood shell heat dissipation is not good, there is no silent shielding effect.
7. If you feel that the standard power is not enough, please detect the power of the power supply in their own hands, if you use a 12V 2A power supply with the board, that is absolutely underpowered. 12X2A = 24W. power supply is not powerful, the amplifier can not output enough energy, remember, it is recommended to get enough power supply to 19V 4.7A or more
