Testing the XY-S350H App Control 220Wx2+350W 2.1 Amplifier Board using the Texas Instruments TPA3251

Texas Instruments TPA3251D2 Ultra-HD Class-D Audio Amplifier
Texas Instruments TPA3251D2 Ultra-HD Class-D Audio Amplifier is a high-performance class-D power amplifier that enables true premium sound quality with class-D efficiency. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra-low distortion across the audio band and superior audio quality. The device can drive up to 2x175W into 4Ω load and 2x220W into 3Ω load. It features a 2VRMS analog input interface that works seamlessly with high-performance DACs such as TI's PCM5242. In addition to excellent audio performance, the TPA3251D2 achieves both high power efficiency and very low power stage idle losses below 1W.

Note:
1)The XY-S350H power amplifier board uses two TPA3251 power amplifier chips.
2)Support wide voltage input:18-36V, power up to 220W*2+350W (PMPO).
3)TREBLE & BASS CONTROL If you are tired of an amplifier with only one volume knob, then you feel right, because you have further requirements for audio.
4)By adjusting the high and low frequency knobs of the XY-S350H power amplifier board, you can make the sound more layered and make the bass more shocking.
5)HIGH COMPATIBILITY The DC adapters on the market (plug size 5.5mm*2.1mm) can basically meet the needs of the XY-S350H Bluetooth power amplifier board.
6)If you don't have a DC plug, please don't worry, you can also directly connect the positive and negative poles of the wire to the power socket of the amplifier board.
PROTECTION FUNCTIONXY-S350H Bluetooth power amplifier board has multiple protection mechanisms to ensure its safe operation.
7)With short circuit protection, under voltage protection, overvoltage protection, clipping protection.
8)IMPORTANT REMINDER the working voltage of the power amplifier board must be above 18V.
DC voltage lower than 18V will fail to start the power amplifier board.
