Feature Highlights:
1. Our company’s UHF, 200-channel series of wireless microphones employs advanced DPLL digital phase-locked loop multi-channel frequency synthesis technology along with automatic noise-control techniques. Operating within a 50 MHz frequency bandwidth at 250 kHz intervals, this series offers up to 200 channel options, complete with lockable control features and adjustable wireless gain connectivity. Additionally, its infrared-based automatic channel-tracking and system-locking functions ensure seamless frequency matching between any transmitter in the series and any receiver—making it especially ideal for use with multiple sets of equipment in the same venue.
2. The display screen shows communication information; the spacious, clear, 2.5-foot HD LCD screen allows you to monitor the wireless unit’s battery level, frequency signal, signal strength, audio power, and other status indicators.
3. The frequency-display screen features color-changing functionality, while the product’s front panel incorporates a dual-layer, two-tone design. Additionally, an external RF signal indicator light and an AF audio level indicator have been added, providing clearer visibility of the receiver’s operational status. The buttons are fully encased in silicone for enhanced light transmission, ensuring a clean and well-organized display.
4. Features a simultaneous output design with both 6.3mm unbalanced and XLR balanced outputs, making it easy to connect to various audio processing devices.
5. Gently turn the VOLUME knob left and right to easily adjust the microphone volume up or down.
6. Equipped with the [AFS] automatic search function, which identifies clean, interference-free frequencies in the actual environment. Simply press and hold SET to automatically scan and lock onto a channel that operates smoothly without interference in your working environment.
7. Equipped with manual frequency adjustment functionality—simply press the ▲▼ buttons briefly when no operation is being performed to fine-tune to the desired frequency point.
8. Equipped with an [IR] infrared automatic frequency-matching function, simply press the SET button briefly. When the display screen flashes "IR," align the IR lights of the transmitter and receiver directly facing each other—this will instantly enable the transmitter to automatically and precisely lock onto the receiver’s operating frequency.
