UHF Dual-Channel Wireless Microphone: Pro-Level Anti-Interference Transmission Powerhouse
LEYE-SU202L, SU202A, SU202B, SU202E, SU202H, SU202T
The LEYE-SU202L UHF Dual-Channel Wireless Microphone System is engineered for professional AV scenarios, operating in the UHF 470-698MHz band (compliant with 520-830MHz national standards), delivering 200 adjustable channels and intelligent digital circuitry for rock-solid frequency stability and robust anti-interference. It tackles traditional wireless mic pain points: signal disruption, frequency drift, and short range. Dual LCD displays monitor RF/AF signals, channels, and ACT status in real-time, with auto-frequency matching and three-level anti-static/lightning protection—ideal for conferences, performances, and broadcasting. Up to 80-100m range (open areas) via FM modulation and high-sensitivity antennas for crystal-clear, noise-free audio.
Product Features
- Uses UHF (Ultra High Frequency) band transmission. Available in A, B, and C frequency groups, each with 200 adjustable channels. Mixed use of multiple groups and channels can meet the requirements of various scenarios.
- Adopts high-precision PLL frequency synthesis and intelligent digital circuitry, offering higher frequency stability. Multiple channels and professional functions can be achieved in one system.
- Strong anti-interference ability to effectively suppress external noise and co-channel interference; features three-level anti-static and lightning protection technology.
- Supports automatic frequency matching technology with auto search and ACT (Automatic Channel Targeting) functions.
- Equipped with high-performance, wide, and clear dual LCD displays showing all operations. Display content includes: RF signal strength, AF signal strength, channel and frequency, ACT status, etc.
