In addition, the independent decoding chip PCM5102 enables the Bluetooth output sound quality to be comparable to that of CD player input, making it very convenient to use. The TPA3255 chip from Texas Instruments features an advanced integrated feedback design and a proprietary high-speed gate driver error correction function (PUREPATH Ultra HD). This technology allows the chip to maintain ultra-low distortion across the entire audio frequency band while delivering perfect sound quality.The D3S can not only adjust the bass and treble of the left and right channels to adapt to different speakers, but also independently adjust the volume and cutoff frequency of the subwoofer output. This enables it to connect well with the left and right channel speakers, making the overall sound field positioning more natural and the low frequency cleaner and more elastic.
