TRAIS UR2D Dual-channel True Diversity Wireless Performance Microphone

Product Features:
● Application types: Tour, large-scale stage performances, large-scale mobile performances, indoor concert halls, multi-function halls, etc.
1. Adopting advanced digital pilot technology, each channel has an independent ID code to prevent frequency crossover; stable PLL phase-locking oscillation circuit, combined with "noise detection" mute control function, can effectively block environmental noise radio interference;
2. True diversity four-way antenna system, built-in antenna distribution system, single-channel AB intelligent reception, effectively enhances dead point handling, realizes continuous frequency reception over long distances, can cope with various complex performance environments;
3. The host provides 5 levels of SQ sensitivity selection, customers can choose the reception sensitivity according to actual usage conditions;
4. System 50KHz step design, manual frequency tuning can adjust up to 500 frequency points for a single channel, a total of 1000 frequency options for dual channels, allowing you to adjust the frequency more precisely and increase frequency utilization rate;
5. All series products adopt full-color high-definition 2.0-inch TFT display, support Chinese/English menus, can quickly switch system languages, system interface provides visual settings for machine number, output gain, group selection, spectrum analyzer, network frequency division, system settings, etc.;
6. The system has real-time spectrum monitoring function, full-band scanning search frequency, 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 tuning visual and more intuitive and accurate;
7. Each channel of the system provides 20*25 preset groups, after third-order intermodulation, can simultaneously call the frequencies within each group for 12 hosts, in the same venue when multiple hosts share, can retrieve the multi-machine frequency table, quickly plan the mutually non-interfering frequency groups, achieving high-efficiency multi-machine usage;
8. The host has channel number setting function, can separately set the number of each channel, after the microphone is frequency-locked with the host, the corresponding channel number is synchronously displayed, avoiding channel confusion, improving on-site operation efficiency;
9. Has network frequency division function, the system provides 20*25 preset groups for each one, after third-order intermodulation, using the data transmission network port, can call all multi-machine frequencies with one click, up to 14 hosts can be supported simultaneously;
10. The host has 10 levels of audio output gain options, can select the appropriate audio output volume according to the on-site requirements;
11. The handheld microphone adopts 0.96-inch TFT screen design, has 3-level gain adjustment, high and low power switching, Chinese/English menu selection and mute function, can prevent accidental operation during use;
12. The host has two independent audio monitoring channels, can choose single channel or select two channels for simultaneous monitoring.
