Core Technology & Performance Highlights

1. Professional UHF Wireless Transmission Performance

• Frequency Range: 663.1-694.1MHz UHF frequency band with pure and stable signals, effectively resisting interference from Bluetooth, Wi-Fi and other devices.
• Oscillation Mode: DSP chip frequency locking ensures stable signal without frequency drift and delivers strong anti-interference capability.
• Frequency Stability: ±10ppm, no frequency offset during transmission for continuous and stutter-free audio output.
• RF Power: 10dBm, supporting an effective transmission distance of 30-50 meters, free of restriction for stage, outdoor and large-space scenarios.
• 2×16 Channel Design: Each of the two microphones supports 16 switchable channels to avoid co-band interference, suitable for multi-device simultaneous operation.
• Automatic Frequency Calibration: Automatic frequency matching upon power-on for plug-and-play use with no manual debugging required, easy for novice operation.

2. High-Fidelity Dynamic Pickup Performance

• Pickup Type: Dynamic microphone cartridge with cardioid directional design, accurately capturing front vocals and effectively suppressing lateral and rear ambient noise.
• Frequency Response: 70Hz~18kHz, covering a wide range of vocal and instrument frequency bands. It delivers full low frequency, transparent mid-range and crisp high frequency, ideal for singing, speeches and instrument sound pickup.
• Ultra-Low Distortion: Total harmonic distortion ≤0.1%, ensuring no sound breakage or distortion even during loud vocal performances and high-pitched singing to restore natural vocals.
• High Sensitivity: The dynamic cartridge finely captures vocal details, clearly recording soft singing and breath sounds.

3. User-Friendly Operation & Low-Latency Experience

• Independent Volume Adjustment: Dual microphones support separate volume control to adjust sound output according to singing styles and scenario demands.
• Low-Latency Transmission: Advanced UHF transmission technology realizes lag-free audio transmission, keeping sound and image synchronized for smooth singing and live streaming experience.
