TRAIS UR2D Dual-channel True Diversity Wireless Performance Microphone

Product Features:
● Application Type: Tour, Large-scale stage performance, Large-scale mobile performance, Indoor concert hall, Multi-function hall, etc.
1. Adopting advanced digital pilot technology, each channel is equipped with 16-bit independent ID codes, eliminating the phenomenon of co-frequency crosstalk; stable PLL phase-lock 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 enhances dead point handling, enabling continuous frequency reception at long distances, capable of coping with various complex performance environments;
3. Receiver provides 5 levels of SQL mute threshold selection, allowing customers to choose the reception sensitivity according to actual usage conditions;
4. The system is designed with 50KHz step size, with manual frequency tuning, each channel can have up to 500 frequency points adjustable, and a total of 1000 frequencies for dual channels, allowing you to adjust the frequency more precisely and increase the frequency utilization rate;
5. All series products adopt full-color high-definition 2.0-inch TFT display screen, supporting Chinese/English menus, allowing for quick system language switching, and visual settings for machine number, output gain, group selection, spectrum analyzer, network frequency division, SQL, system settings, etc.;
6. The system has real-time spectrum monitoring function, full-band scanning search for frequencies, capable of detecting the on-site environment and displaying the existing frequencies and intensities in the space, allowing for intuitive selection of clean working frequencies, making frequency tuning visual and more intuitive and accurate;
7. Receiver has channel number setting function, allowing for individual setting of each channel's number. After the microphone and the receiver are frequency-aligned, the corresponding channel number is synchronously displayed, avoiding channel confusion and improving on-site operation efficiency;
8. It has a network frequency division function, with the system providing 20*25 preset groups for each channel. Using the data transmission network port, all multi-channel frequencies can be called at once. A single frequency group can support up to 15 receivers to be called simultaneously, quickly planning mutually non-interfering frequency groups, avoiding third-order intermodulation, achieving high-efficiency multi-channel usage, and in the same frequency band, up to 40+ channels can be used;
9. Receiver has 10 levels of audio output gain options, allowing for selection of the appropriate audio output volume according to the on-site requirements;
10. Receiver has built-in transmitter function preset: it can preset the power value and pickup sensitivity of the transmitter in the receiver;
11. Handheld microphone adopts a 0.96-inch TFT liquid crystal screen, using the current advanced full-coating technology, allowing for clear and seamless display of content, with 3 levels of gain adjustment, high and low power switching, Chinese and English menu selection, and mute function, preventing accidental operation during use;
12. Receiver has two independent audio monitoring channels, allowing for selection of single channel or simultaneous monitoring of two channels;
13. Receiver has a one-click mute function. By simply pressing the power switch, Receiver system directly goes into mute mode, facilitating the control personnel to mute all the microphones that are not in use.
