Description:

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. Adopt TPA3255, (5.0 Bluetooth adopts Qualcomm QCC3003 )

2. The main filter electrolytic capacitor uses 1000UF/80V to ensure strong and continuous power support.

3. Use red and gray ring high current inductance 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 current.

6. Adopt all-aluminum chassis, the surface of the chassis is all treated with oxidation process!

7. Two input methods: analog and Bluetooth input. (Bluetooth input is preferred when both modes are input at the same time. After 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)
