2x60W High Power 2-Channel Stereo TPA3221 Power Amplifier Board HiFi Digital Audio Amplifier Module

Specification:
- Power amplifier type: class D HiFi digital power amplifier board
- Power amplifier chip model: for TI advanced TPA3221D2DDVR high definition class D power amplifier IC
- SNR: 108dB
- Distortion: <0.02%, THD+N 1kHz
- Gain: 30dB
- Supported speaker impedance: 4 - 8ohms
- Output power: max. 2 x 60W
- Channel number: 2-channel stereo
- Power supply voltage/current: DC9 - 17V, 3A above (The charger is likely not functioning properly, please use a power adapter or switch power supply.)
- Audio source input: XH2.54
- Size: 80 x 39.5mm

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 NIPPON ultra-low impedance large capacitors and for Siemens film capacitors are used.
- Using audio specific copper strip inductors, the sound is clear and transparent.
- 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
