TPA3255 Bluetooth 5.0 Power Amplifier 325Wx2 Bluetooth QCC3034 APTX Stereo Audio Amp Sound Amplifier Speaker 

 1. Using TPA3255, QCC3034 Bluetooth 5.0 chip; The main filter electrolytic capacitor uses 1000UF / 50V imported from Japan to ensure strong power support. 

2. Adopt special high-current inductance of red and gray ring for audio to ensure the sound is crisp and powerful. 

3. PCB adopts 1.6mm thick double-sided board, 2.0 ounces copper thickness, and full tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality. 

4. All-aluminum chassis is adopted, and the surface of the chassis is processed by wire drawing oxidation coloring process! 

5. Input mode: analog and Bluetooth input function. When both modes are input at the same time, Bluetooth input takes priority. After Bluetooth connection, RCA input is automatically disconnected; when analog input is required, please turn off the Bluetooth function of the mobile phone before switching
