1. Parts Selection: Two audio are used, and the transformer material is from aerospace materials.
2. High sensitivity and high reduction, 10-20DB higher sensitivity than similar low-end , full tone, quality.
3. Line design: stereo two-channel design, circuit board specifications: 45MM X 30MM, very small, suitable for small cars and other interior installations.
4. Connection : Two connection methods, which can be input and output through a 3.5MM headphone jack, or can be directly wired through two blue wiring jacks.
5. Main function: Eliminate current sound. A common ground-isolated audio transformer eliminates current noise from the AUX common ground. The output and output ground lines are isolated by the transformer and there is no common ground.
