GEN4 1Key 3S Re-Pair Cuts 93% Hassles Anti-inteference, Portable Wireless Microphones SA310-H37 for Singing, Karaoke, Meeting, Stage Performance

RELIABLE HISTORIES OF YEAMIC - 22 years of company & brand reputation, 33 years of wireless microphone technology development experiences for stage performance, YEAMIC independent industrial park spanning over 13,000 square meters in Guangdong, CN. Yeamic has spent millions of dollars and five years to develop Gen4 and Gen5, automated maintenance technologies capable of handling signal interference and pairing. Compared to other UHF singing microphones on the market during 2014-2025, Gen4 and Gen5 technologies can save 93% (Gen4) and 99.9% (Gen5) of the time and cost for signal maintenance in stage usage. YEAMIC SA-310 HOST SERIES Built-in YEAMIC GEN4 Technology - AUTOMATIC PAIRING & AVOIDING INTERFERENCE BY A KEY WITHIN 7 SECONDS; WORK EFFICIENCY INCREASED BY 15 TIMES* (compared to mainstream UHF singing & stage MICs on market during 2024 to 2025); Max Transmission Distance 60 to 80 meters (but suggest to use it within 1/5 of MAX TRANSMISSION for stability) Microphone Parameters Frequency Range: UHF (537MHz-589MHz) Avaiable Channels: 480 channels with adaptive adjustment Frequency Stability: ±10ppm Frequency Modulation: FM Radio Frequency Power: 10~30mW adaptive adjustment Audio Frequency Response: 40~18000Hz Distortion: ≤1% Speech Head: Dynamic, Cardioid Polar Pattern Battery: Rechargeable 1200 mAh / per microphone, total 2400mAh.

• UNIQUE GEN4 TECH: YEAMIC smart chips built-in, frees you from manual frequency pairing. Every time the mic is powered on, it will automatically complete interference avoidance, frequency scanning, best frequency selection and re-pairing -- all within 2 seconds (normal IR-Paired UHF Mic needs about 100 seconds, Gen-4 saves 93% of you time on signal setup). No extra manual intervention required, drastically cutting down setup and tuning time so you can focus on your event, not your gear.
• UHF TRANSMISSION: Designed exclusively for stage performance and singing. Latency under 3ms delivers smooth vocal sync. Resists obstruction and signal interference steadily. （Common 2.4G, 5G and Bluetooth technologies have weaker obstacle penetration, prone to interference, with latency ranging from 8 to 20ms.）
• Portable Size - They can be put into handbags or backpacks
• SOUND QUALITY: YEAMIC is committed to delivering reliable, crystal-clear audio performance. This model is specifically optimized for frequent use in school halls, KTV rooms, and social gatherings. With its integrated analog reverb processing, it delivers a warmer, more balanced vocal presence, making it a dependable workhorse for both commercial and private environments.
