Design principles:
1. The Audio Grounding Box removes interference (EMI/RFI) from the sound system in an independent and direct manner, bringing this value to 0V. Improves the loudspeaker sound quality.
2. Audio Grounding Box provides a unified reference point for the entire sound system, reducing mutual interference between equipment. The sense of music is strengthened.
3. With passive design, Audio Grounding Box itself does not have any tone, it will not change the balance of the system.

Audio effects

1. The sound system background becomes darker and more quiet;
2. The details increase, the sound is clean without losing fullness, and the high frequency is round;
3. After the sound field moves backward, the instrument has higher separation degree, better dynamics, and the sound field becomes three-dimensional.

Before use

2.Audio Grounding Box can be used in at least 48 hours to achieve the design effect; use the product for a period of time to comment.
