Features: Use original TPA3255 (5.0 Bluetooth uses QCC3003 chip)The main filter electrolytic capacitor uses 1000UF/80V to ensure strong continuous power supportThe red-grey ring high-current inductor is used to ensure the sound is clear and powerfulPCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB qualityThis machine adopts an all-aluminum chassis, and the surface of the chassis is treated with drawing oxidation coloring processInput mode:analog and Bluetooth input function. When the two methods are input at the same time, the Bluetooth input has priority. After Bluetooth is connected, the RCA input is automatically disconnected; when analog input is required, please turn off the Bluetooth function of the mobile phone to switch.Working method:Class DWorking voltage:DC30V-48VSize:180*100*40mm, antenna length 105mmThe total output power when the total harmonic distortion
