Adopting TPA3255 chip, audio power core, high efficiency, low power consumption, high-definition sound quality, and comprehensive protection mechanism. <br/>2. With protection function, reverse power protection is safer. <br/>3. Easy to use, independent tuning of high and low frequencies, more convenient to use. <br/>4. Low loss, using digital amplifier specific inductors for lower losses. <br/>5. Multiple decoding options, supporting Bluetooth audio decoding and USB flash drive decoding.</p><p>Product Introduction: <br/>This model is designed with 2 original imported TPA3255 amplifier chips, with dual cores for greater stability. TPA3255 is a high-performance D-class power amplifier that has D-class efficiency and can deliver truly high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath HD). This technology enables devices to maintain ultra-low distortion across the entire audio frequency band while showcasing high-definition sound quality.</p><p>Parameter: <br/>Product Name: Bluetooth Audio Amplifier <br/>Product Model: XY-AS21HPA <br/>Power supply: DC19-51V/10A or above <br/>DC socket interface: 5.5-2.5mm <br/>Bluetooth version: 5.2 <br/>Audio input: Bluetooth+AUX+USB flash drive+USB sound card <br/>Bluetooth audio decoding: AAC SBC <br/>USB decoding: WAV, FLAC, APE, MP3 <br/>Left and right channel output power: <br/>30W+30W @ 8Ω/24VDC <br/>70W+70W @ 4Ω/24VDC <br/>80W+80W @ 8Ω/36VDC <br/>160W+ 160W@4 Ω/36VDC <br/>160W+ 160W@8 Ω/50VDC <br/>300W+ 300W@4 Ω/50VDC <br/>Subwoofer output power: <br/>30W @ 8Ω/24VDC <br/>70W @ 4Ω/24VDC <br/>150W@2 Ω/24VDC <br/>80W @8Ω/36VDC <br/>160W@4 Ω/36VDC <br/>350W@ 2Ω/36VDC <br/>160W@8 Ω/50VDC <br/>300W@4 Ω/50VDC <br/>600W@ 2Ω/50VDC <br/>Size: <br/>Integrated potentiometer: 124 * 124 * 32mm <br/>Integrated shell: 124 * 142 * 44mm <br/>External potentiometer: 124 * 124 * 32mm</p><p>Package include: <br/>1X power amplifier board(including accessories)<br/><br/></p></div></div><p><br/></p>
