This UHF wireless microphone system adopts advanced PLL (Phase Locked Loop) frequency synthesis technology, providing 200 adjustable frequency points. Covering a wide range of 460-950MHz, it supports dual-channel reception, meeting the needs of multiple devices simultaneously. The system features antenna grading design and "noise locking" functions to shield environmental RF interference.
Equipped with a one-click [IR] infrared synchronization function. Simply press to automatically sync the receiver frequency to the transmitter, eliminating tedious manual modulation and ensuring efficient, accurate operation for professional stage or conference environments.
±0.0005% ultra-high frequency accuracy combined with PLL phase-locked loop control eliminates frequency deviation. With a maximum deviation of only ±45KHz, the system ensures zero interruptions or signal delays during critical performances.
In open environments, transmission reaches up to 100 meters. The dynamic directional microphone unit provides a frequency response of 45Hz~18KHz, with total harmonic distortion under 0.4%. Experience clear, delicate sound quality for both vocals and instruments.
Utilizing high energy-density lithium batteries, this system offers up to 20 hours of battery life with repeated use in the charging case. Lithium batteries provide stable voltage and current, reducing noise and distortion while aligning with environmental protection goals by reducing disposable battery waste.
