Advantage
Professional UHF wireless microphone system - high fidelity 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.
Core 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.
Professional parameter configuration
√ Receiver: Dual channel design, sensitivity>105dB, supports 80MHz bandwidth, suitable for multi scene signal reception; 100-240V wide voltage supply, compatible with global power standards.
√ Transmitting end: optional 8mW/12mW RF power, flexible to meet different environmental requirements; Powered by 2 AA batteries, the battery life can last up to 8 hours, and the low-power design (120mA) extends the usage time.
√ Safety compliance: Harmonic radiation<-63dBm, in compliance with electromagnetic compatibility standards, to avoid interference with other devices.
