Cut 93% Signal Maintenance Time & Cost | Stackable SA300 Wireless Mics GEN4 Tech Automatically Optimize Signal to Pair Within 2 Seconds After Power on for Church, Karaoke, Party, PA

Why Choose Us? SA300 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. Max Transmission Distance (open area): 80 meters / 262.5 ft to 100 meters / 328.1 ft . Practical Transmission Distance: To ensure stability, suggest to estimate as "MAX Transmission Distance"/5 (80meters/5=15 meters) Microphone Specifications: Frequency Range： 537MHz-589MHz Available Channels: 480 Auto-Adaptive Frequency Stability: ±10ppm Speech Head: Dynamic, Cardioid Polar Pattern Audio Frequency Response: 40~18000Hz Distortion (THD): ≤0.8% Radio Frequency Power: 10~30mW adaptive adjustment Battery of Microphone: AA size battery x 2 per mic (not included in the device) Battery Duration: 4~8 Hours depending on the mAh of your AA battery Receiver Specifications: Frequency Range： 537Mhz-589MHz Available Channels: 240+240 Auto-Adaptive Oscillation Mode: Phase-Locked Loop (PLL) Frequency Synthesis Frequency Stability: ±10ppm Receiving Mode: Superheterodyne Double Receiver Sensitivity: -103dBm Audio Frequency Response: 40~18000Hz Distortion (THD): ≤1% Signal-to-Noise Ratio: ≥100dB Audio Output: Φ6.35 Socket Mixed Unbalanced DC Adapater: DC12V/1000mA Power Consumption ≤8W

• UNIQUE YEAMIC GEN4 TECHNOLOGY BUILT-IN: Reducing maintenance costs by 90% compared to manual RF Pairing UHF Mic system during 2014 to 2025- Restart POWER button to complete INTERFERENCE AVOIDANCE, FREQUENCY SCAN, BEST FREQUENCY SELECTION and RE-PAIRING within 7 SECONDS, WORK EFFICIENCY INCREASED BY 15 TIMES* (compared to mainstream UHF Manual IR Pairing Mics on market). -- We are glad to cooperate with other branded microphone companies with this technology; welcome to contact OFFICIAL YEAMIC.
• UHF Transmission - Sound delay < 0.001ms (electroacoustic transmission and conversion at the speed of light, imperceptible to humans); Long transmission distance; Strong resistance to dead zones; Strong ability to overcome obstacles (human body and walls); adjustable frequency to avoid signal interference. Max Transmission Distance 80 meters / 262.5 ft to 100 meters / 328.1 ft (but suggest using it in 1/5 of MAX TRANSMISSION for stability).
• Stackable installation in standard full-size cabinets
• Optimized sound effects more suitable for the general public singing rather than professional singers.
• Because we cannot guarantee 100% QC inspection results, we offer a 3-month return and refund service, please contact seller if you need this.
