1. and high-quality products.
2. Made of high-quality materials, and practical.
3. Fine workmanship and good performance.
4. Long service life.
5. A special amplifier board for electret microphones powered by 48V phantom power, universal and single-point electret microphones.

By matching the microphone with different parameters, it can be used for karaoke, recording, conference speech and so on.
The bottom noise of the amplifier board has a lot to do with the microphone. It is recommended to use a low-noise electret microphone to achieve the desired effect.
