WHAT IS NEW IN THE ATS MINI V.4 UPGRADE:
1. A shielding cover is added to the receiving part of Si4732 to suppress electromagnetic interference; An ESD device is added to the antenna input end to protect the chip's safety.
2. The Hi-Z circuit was moved to the front end of the antenna path and a more stable VCC_RADIO power supply was adopted to retain signal resonance and reduce noise.
3. A new function of using wired headphones as FM antennas has been added (headphones are not included in the shipping list. Please prepare them by the buyer; they need to be used in an environment with strong FM signals and the headphone cable should be relatively long to achieve better performance).
4. The left and right channels have been swapped. At the same time, readjust the parameters of the power amplifier and speakers to enhance the sound quality.
5. More expensive and superior accessories were replaced: a more sturdy and durable telescopic antenna, and a more comfortable and anti-slip knob hat
6. A version of the CNC housing has been added as a new option
