Advantage
Professional recharging UHF wireless microphone system - high sensitivity transmission, stable anti-interference
This UHF wireless microphone system adopts advanced PLL (Phase Locked Loop) frequency synthesis technology, providing 200 adjustable frequency points, covering a wide frequency range of 460-950MHz, supporting dual channel reception, and meeting the needs of multiple devices for simultaneous use. The system has excellent anti-interference ability. Through antenna grading design and "noise locking" function, it effectively shields environmental RF interference, ensures signal purity and stability, and is suitable for professional scenarios such as performances, conferences, and teaching.
Advantages
Intelligent frequency synchronization
One click [IR] infrared synchronization function, press to automatically synchronize the receiver frequency to the transmitter, eliminating the tedious manual frequency modulation and ensuring efficient and accurate operation.
High stability transmission
± 0.0005% ultra-high frequency accuracy, combined with PLL phase-locked loop control, eliminates frequency deviation problems, with a maximum frequency deviation of ± 45KHz, ensuring no frequency interruption or delay in sound.
Long distance high fidelity
In an open environment, the transmission distance can reach 100 meters. The dynamic directional microphone unit, combined with FM modulation, has a frequency response range of 45Hz~18KHz (± 3dB), with a total harmonic distortion of<0.4%. The sound quality of human voice and instruments is clear and delicate.
Stable Performance and Energy-Friendly and Energy-Saving
Compared to other microphones that use disposable or traditional rechargeable batteries, lithium batteries have a higher energy density and offer longer battery life. With repeated use in the charging case, the battery life can reach up to 20 hours.
Lithium batteries are rechargeable, reducing the use of disposable batteries and environmental pollution, thus aligning with environmental protection.
Lithium batteries provide stable voltage and current, ensuring consistent microphone performance and reducing noise, distortion, and other issues caused by unstable power sources.
