Product introduction:
1: This product integrates the current TPA3255 power module with very low distortion and the Bluetooth decoder module QCC5125 that supports LDAC and APTX, and integrates the PCM5102A high-end decoder chip. Other materials are not considered cost, so the listening performance, low frequency and strong, human The sound is warm and the high frequency penetration is very good. And with 2 high and low bass adjustments, easy to use
2: The price of this product is relatively high, because Bluetooth is the top QCC5125 with independent decoding, and the output inductor is also an expensive black crystal common mode inductor!
3: TPA3255 is a high-performance class D power amplifier chip, which has class D efficiency and can bring real high-end sound quality circuits. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath™ Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device works in AD mode. When the THD is 10%, it can drive up to 2 315W/4R loads and 2 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface that supports high-performance DAC (For example, TI's PCM5242) seamless connection. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle loss (less than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this solution can significantly reduce idle loss.
4：Bluetooth is very simple to use, turn on the mobile phone Bluetooth, find the Bluetooth device, and pair the link. After disconnecting the Bluetooth, you can connect to the 3.5MM stereo audio wired input
