120W High Power Mono Stereo Class D TPA3221 Power Amplifier Board HiFi Digital Audio Amplifier Module

Specification:

- Power amplifier type: mono 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: 2 - 8ohms

- Output power: max. 1 x 120W

- Channel number: mono 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 37mm

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, for WIMA, EVOX and other HiFi 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
