TPA3255 QCC3003 300W*2 Professional Stereo bluetooth 5.0 Digital Power Amplifier Class D HiFi Amplifiers

Features:Using original TPA3255,QCC3008 Bluetooth 5.0 chipThe main filter electrolytic capacitor uses 1000UF/50V imported from Japan to ensure a strong source of continuous power supportAdopt special high-current inductance of red and gray ring for audio to ensure the sound is crisp and powerfulPCB adopts 1.6mm thick double-sided board, 2.0 ounce copper thickness, full tin spraying process to ensure good passing performance of large and small currents. First-class PCB qualityThe machine adopts all-aluminum chassis, and the surface of the chassis is processed by brushing oxidation coloring processInput 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 switchingSpecification:Working method: Class DWorking voltage:DC24V-42V(recommended DC36V,excessive voltage and severe heat)Size: 160 x 126 x 42mm, antenna length 105mmTotal output power when total harmonic distortion+noise(THD+N)is 1% (240W/4Ω)*2, Total output power when total harmonic distortion+noise(THD+N)is 10% (325W/4Ω)*2TPA3255 2.0 Stereo Bluetooth Digital Amplifier D90(bluetooth 5.0APTX 300W+300W)Package Included:1 xTPA3255 Amplifier
