USB can support all lossless format audio file playback (WAV FLAC APE WMA MP3, etc.) a variety of audio formats!
TPA3156D2 power amplifier board output power: 2*70W+140W4Ω, power supply is 24V10A. (Amplification gain is 36dB for subwoofer + 32dB for left and right channels)
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)
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)
1. Wide voltage power supply: 8V-24V DC power supply (cannot connect to transformer)
2. Different voltage outputs different power: voltage X current = power (the conversion rate of this board is 90%)
3. The digital power amplifier voltage activation output current parameters are as follows:
8 V 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!
Note:
When the AUX audio input and USB cable are used to shoot the bare board, please contact customer service if you need it (the bare board is a pure Bluetooth power amplifier board. Buyers who solder AUX and USB after the test are not guaranteed!! !)
