<div>Welcome to our store! We hope you have a wonderful shopping experience!</div>

<ul><li>Now it is the latest version, which completely improves the common problem of high-voltage protection. It is completely normal to use 50V, and the materials used are also more heated. The auxiliary power supply uses a Class A linear power supply, which is more dynamic and significantly improves the sound quality! It can perfectly drive 2-16 ohm speakers!TPA3255 is a high-performance Class D amplifier chip with Class D efficiency, which can bring a true high-end sound quality circuit. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power consumption level idle loss (less than 2.5W). This can be achieved with 85mR MOSFET and optimized gate driver solution. Compared with traditional discrete implementation solutions, this solution can significantly reduce idle loss.<br>
Amplifier IC:TPA3255 chipInput method:3.5M stereo wired socket interface (3P)Work efficiency:Greater than 90% The upgrade board has Bluetooth 5.1 input methodOutput power:315W/4 ohms, distortion 1.5% 185W/8 ohms, distortion 1.5%, 260W/4 ohms, distortion 19%, 150W/8 ohms, distortion 19%Frequency response:20Hz to 20KHzDynamic range:Greater than 100dBSignal-to-noise ratio (SNR):Greater than 111dbColour:BlackMaterial:Plastic<br>
