TRAIS UR750 Dual-channel True Diversity Wireless Performance Microphone
Product Features:
● Application Type: Small and medium-sized stage performances, multi-function halls, etc.;
1. Adopting advanced digital pilot technology, stable PLL phase-locked oscillation circuit, combined with "noise detection" mute control function, can effectively block the noisy radio frequency interference in the environment;
2. True diversity four-way antenna system, single-channel AB intelligent reception, effectively enhance dead point handling, achieve continuous frequency reception over long distances, can cope with various complex performance environments;
3. System 50KHz step design, manual frequency adjustment allows up to 100 frequency points per single channel to be adjustable, a total of 200 frequency options for dual channels, enabling you to adjust the frequency more precisely and increase the frequency utilization rate;
4. All series products adopt full-color high-definition 2.0-inch TFT display, dual-color display settings, capable of displaying orange and green;
5. The system has real-time sweep frequency function, full-band scanning search for frequencies, can detect the on-site environment and display the existing frequencies and intensities in the space, can intuitively select clean working frequencies in the spectrum, making frequency adjustment visualized and more intuitive and accurate;
6. The receiver has 30 levels of audio output gain options, which can be selected according to the on-site requirements for the appropriate audio output volume;
7. The host has dual-band dual-mode function, can be switched to another frequency point with one click, can be set as handheld, waist bag, conference, making it easier and more convenient to use.
