Power Amplifier Board Digital 2 Channel Potentiometer Module TPA3221 GEO
- The use of special magnetic ring inductance for audio ensures that the sound is clear and powerful.
- Small size, easy to carry and store, convenient to use and with good performance.
- The whole process of spraying tin to ensure good passing performance of large and small currents.
- Using 1.6mm thick PCB double‑sided board, strong and durable, has a long service life.
- The resistors are high-accuracy chip resistors to ensure a good signal-to-noise ratio of the whole machine.
