2.1 Channel Power Amplifier Board TPA3118D2 2X30W 60W High Power Bluetooth5.0 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. TPA3118D2 power amplifier board output power: 2*30W 60W8Ω, power supply is 24V5A. (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 the subwoofer speaker with a size of 6.5 inches or more and 4 euros and below 60W!
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*30 60W) 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: TPA3118D2*2
Bluetooth version: 5.0
Amplifier channel: 2.1 three-channel
Supply voltage: DC8V-24V
Supply current: 3A-10A
Output power: 2*30 60W
Output Impedance: 8 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 activatedoutput 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!
