Feature：
1. Solid structure, stable and reliable performance, easy operation, and perfect sound presented.
2. Adopt PLL phase-locked loop multi-channel frequency synthesis technology.
3. Super anti-interference ability, can effectively suppress noise interference and co-channel interference caused by the outside.
4. Provide 200 preset channel options, true diversity reception, effectively avoid frequency interruption and extend the receiving distance.
