2x175W Class D HiFi Digital Power Amplifier Board TPA3251 2-Channel Stereo Amplifier Module

Note:
- This power amplifier board has two input methods: single-ended input/balanced input; please leave a message for the input method you need before payment.
- Input Method 1: single-ended input (i.e. commonly used audio signal input method, with a total of three pins, namely left channel audio signal terminal, ground, and right channel input terminal)
- Input Method 2: balanced input (i.e. high-performance audio signal input method, with a total of six pins, namely the positive, ground, and negative terminals of the left channel audio signal terminal, and the positive, ground, and negative terminals of the right channel input terminal)

Features:
- HiFi power amplifier chip, low-noise power supply design, rigorous power amplifier board design, luxurious materials, and added dedicated protection chip.
- The PCB uses TG150 high-temperature characteristic board, and the immersion gold process makes the product more beautiful and durable; Matte blackboard looks better (note that the color of the board does not affect its performance).
- HiFi grade electronic materials: low-temperature drift high-precision resistors are used for the sound path patch. All surface mount capacitors are made of at least X7R material. Large volume MLCC capacitors for power supply, for WIMA/RIFA/NICHICON/MUSE/KZ capacitors and for ELNA series ultra low impedance capacitors are used.
- The whole machine adopts plug-in re-soldering technology, with smooth and firm solder joints, reducing the interference effect of the tip and making the sound quality purer.

Package Included:
- 1 x Power Amplifier Board
