The TPA3255 is a high performance Class D power amplifier with Class D efficiency and true to high-end sound quality. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePathTM Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the audio band while delivering perfect sound quality.
1. Using original TPA3255 digital power amplifier chip, PCM5102 decoder chip, Qualcomm QCC3003 5.0 Bluetooth chip
2. The main filter electrolytic capacitor is 1000UF/50V, which ensures strong and continuous power support.
3. The red-ash ring high-current audio special inductor is used to ensure the sound is crisp and powerful.
4. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. First-class PCB quality.
5. This machine adopts all-aluminum chassis, and the surface of the chassis is all processed by wire drawing oxidation coloring process!
6. Bluetooth 5.0 version uses all-aluminum precision knob.
7. Input method: analog and Bluetooth input function.
Bluetooth input takes precedence when both modes are input at the same time.
After the Bluetooth connection, the RCA input is automatically disconnected; when the analog input is required, Please turn off the Bluetooth function of the mobile phone to switch
