Equipped with a special wide UHF frequency band design to prevent frequency interference from other electronic industries. The multi-channel digital phase-locked loop (PLL) frequency synthesis technology provides up to 200 selectable channels, making it convenient to avoid various types of interference even when multiple units are used simultaneously.
Features advanced infrared synchronization for automatic frequency matching. Even if the transmitter and receiver settings become chaotic, a simple push of a button will automatically lock the transmitter frequency to match the receiver. This quick and simple operation includes a lock function to prevent accidental misuse during performances.
The high-definition LCD screen provides clear visibility of core parameters including current channel, volume level, battery status, and signal strength. Users can monitor the device status at a glance. Real-time feedback during channel switching or volume adjustment ensures precise control and avoids operation errors.
Equipped with premium high-sensitivity cartridges that offer powerful sound pickup, high output levels, and efficient noise resistance. It ensures smooth, undistorted vocal transmission, making it ideal for outdoor performances, conference rooms, classrooms, bars, KTV, and professional stages.
The typical operating range is between 80 to 100 meters in open space, thanks to its stable UHF frequency transmission.
The system utilizes PLL frequency synthesis technology to provide up to 200 individual channel selections.
The system features an Auto Infrared frequency match. Simply press the sync button, and the receiver will automatically lock onto the transmitter's frequency.
The transmitter uses two AA batteries, providing approximately 8 hours of continuous operation depending on usage conditions.
