This product is designed for the most demanding and high fever musicians. It integrates the TPA325 5 power module with very low distortion and the QCC3095 Bluetooth decoding module that supports LDAC and APTX, as well as the PCM5102A high-end decoding chip. Other materials are also cost-effective, resulting in excellent listening performance, rich low frequencies, warm vocals, and high frequency penetration. And it comes with two adjustable high and low frequencies for easy use. (Power statement: The output power of this product is closely related to the matching power supply. If your speaker is not large, you can use a small 19V power supply. If it is a 10-12 inch or dual 8-inch speaker, it is best to use a 36V-48V DC power supply to achieve maximum effect.). Please do not evaluate the output power as insufficient when paired with a power supply of less than 100W. As long as there is a power supply with sufficient power, the absolute effect will be explosive
The price of this product is relatively high because Bluetooth is the top of the line Bluetooth 6.2QCC3095, which also comes with independent decoding, and the output inductor is also an expensive black crystal common mode inductor!
TPA3255 is a high-performance Class D power amplifier chip that has Class D efficiency and can deliver truly high-end sound quality circuits. This device features a unique integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology enables devices to maintain ultra-low distortion throughout the entire audio frequency band while showcasing sound quality. This device operates in AD mode and can drive up to 2 315W/4R loads and 2 150W (uncut power)/8R loads at a THD of 10%. It also features a 2VRMS analog input interface that supports seamless connection with high-performance DACs such as TI's PCM5242. In addition to its audio performance, TPA3255 also has two advantages: power efficiency and ultra-low power idle loss (less than 2.5W). This can be achieved through an 85 mRMOSFET and an optimized gate driver scheme. This scheme can significantly reduce idle losses compared to traditional discrete implementation schemes.
