TPA3116D2 2.1 Channel Power Amplifier Board 2X 50W+100W High Power BT 5.0 Subwoofer Class D Amplifier Board DC8V-24V

1. TPA3116 series subwoofer high-fidelity 2.1 power amplifier board, onboard Bluetooth 5.0 chip, supports the installation of AUX (audio input) and USB (playing U disk and card reader), and can also be installed with IR (remote control function) and AD_KEY ( button control)!

2. USB can support all lossless format audio file playback (WAV FLAC APE WMA MP3, etc.) a variety of audio formats!

3. TPA3116D2 power amplifier board output power: 2*50W+100W4Ω, power supply is 24V8A. (Amplification gain is 36dB for subwoofer + 32dB for left and right channels)

4. The gain of the bass channel of the power amplifier board is 36dB. The output power is relatively large, please try to connect a subwoofer speaker with a size of 6.5 inches or more and 4 euros and below 100W!

5. The gain of the left and right channels is 32dB, and it can be connected to a 3-6.5 inch high and low frequency speaker power amplifier board within 8 ohms and 30W. The power supply requirements are 8-24V (8V can be turned on, not 8V power supply can reach 2*50+100W) 24V5A power supply above To achieve the best output value, (buyers who use power below 21V are not responsible for the output effect) please use a power supply above 24V5A!

Specification:

Product name: 2.1 channel bluetooth power amplifier board

Power amplifier chip: TPA3116D2*2

Bluetooth version: 5.0

Amplifier channel: 2.1 three-channel

Supply voltage: DC8V-24V

Supply current: 3A-10A

Output power: 2*50+100W

Output Impedance: 4 ohm

Amplification gain: 36db-32db

Distortion ratio: THD-1%

Product size: 96 x 40mm

Wide voltage power supply: 8V-24V DC power supply (can not be connected to a transformer)

Different voltage outputs different power: voltage X current = power (the conversion rate of this board is 90%)

The digital power amplifier voltage activated output current parameters are as follows:

8V power supply maximum 3A current = 24W (total power) 90%

12V power supply maximum 5A current = 60W (total power) 90%

18V power supply maximum 6A current = 108W (total power) 90%

24V power supply maximum 8A current = 192W (total power) 90%

That is to say, in the state of 8V power supply, the maximum current is 2A, that is, 3X8=24W and so on!

Colour:black+green

Material:PCB+Metal
