Features
● Employs true diversity UHF technology with superior anti-interference ability, eliminating the worry of frequency interruption during use.
● True diversity receiver with independent selection system for each channel, minimizing the occurrence of signal dropouts.
● Dual-channel independent SC frequency automatic search function, quickly scanning and locking onto the least interfered frequency in the working environment.
● Each channel has an independent digital display for channel and frequency, allowing users to understand the operation of the host at a glance.
● The receiver host features a high-definition LCD screen with clear content display.
● The receiver and transmitter sync with a dedicated frequency pairing technology, allowing one-touch synchronization.
● Professional performance-level phase-locked circuits, combined with noise lock quiet control and digital pilot technology, mute the AF signal to suppress noise when the transmitter is off, ensuring effective isolation against interference signals.
● The high-definition display indicates RF and AF signal strength, frequency, frequency group, channel, and other working statuses.
● CPU bus control, combined with a digital LCD interface display, offers smooth operation and outstanding performance, with multiple noise monitoring circuits and a special ID code verification system for superior anti-interference capabilities.
● Feedback howl suppression function, effectively reducing feedback howls.
● The true diversity wireless system is designed specifically for fixed installation purposes, providing the highest reliability, sound quality, and transmission stability.
● Open usage range of 200 meters; compatible with a variety of microphones including handheld, headset, lavalier, and desktop gooseneck microphones.
